One of humanity's greatest triumphs is the eradication of smallpox. Many doctors and scientists thought it was impossible to eliminate a disease that had been around for millennia and killed nearly 1 in 3 people infected. Smallpox is the first and only human disease to be wiped out globally.  

KFF Health News held a web event Thursday that discussed how the lessons from the victory over smallpox could be applied to public health challenges today. The online conversation was led by Céline Gounder, physician-epidemiologist and host of “Eradicating Smallpox,” Season 2 of the Epidemic podcast.

Gounder was joined by:

Helene Gayle, a physician and epidemiologist, is president of Spelman College. She is a board member of the Bill & Melinda Gates Foundation and past director of the foundation's HIV, tuberculosis, and reproductive health program. She spent two decades with the Centers for Disease Control and Prevention focusing primarily on HIV/AIDS prevention and global health.

William “Bill” Foege was a leader in the campaign to end smallpox during the 1970s. An epidemiologist and physician, Foege led the CDC from 1977 to 1983. He appears in the virtual learning series “Becoming Better Ancestors: Applying the Lessons Learned from Smallpox Eradication.” Foege is featured in Episode 2 of the “Eradicating Smallpox” docuseries.

TRANSCRIPT  

[The video trailer for season 2 of the Epidemic podcast, “Eradicating Smallpox,” begins to play] 

Céline Gounder: Bangladesh 50 years ago, we were on the cusp of something big, something we had never done before. We were about to wipe smallpox off the planet. It's one of humanity's greatest triumphs. One public health has yet to repeat. I'm Dr. Celine Gounder. I'm a physician and epidemiologist. 

This season of Epidemic, we're going to India and Bangladesh, where smallpox made its last stand, to understand how health workers beat the virus. The question I'm asking, “How can we dream big in public health again?” From KFF Health News and just human productions, Epidemic, eradicating smallpox. Listen wherever you get your podcasts. 

[Video trailer ends]  

Céline Gounder: Good morning everyone, and thanks for joining us today. I'm Dr. Celine Gounder. I'm editor-at-large for Public Health at KFF Health News and I'm the host of the Epidemic Podcast. In today's conversation, we're going to talk about lessons to be learned from the eradication of smallpox and how those can be applied to public health challenges today. The eradication of smallpox is one of humanity's greatest triumphs. Many doctors and scientists thought it was impossible to eliminate a disease that had lasted for millennia and killed nearly one in three people infected. Smallpox remains the first and only human disease to be wiped out globally. 

Just a few logistical details before we get started. The briefing is being recorded and the link to the recorded version will be emailed to everyone later today.

I'd like to move forward with introducing our panelists today. Dr. Bill Foege is an epidemiologist and physician and was a leader in the campaign to end smallpox during the 1970s. Foege is featured in episode two of the Eradicating Smallpox docuseries, and he's also featured in the Nine Lessons series produced by the Becoming Better Ancestors Project. The Nine Lessons, available at ninelessons.org, is a virtual learning series about how the lessons from smallpox eradication could be applied to COVID and other public health and societal challenges. 

Also, joining us today is Dr. Helene Gayle, who's also an epidemiologist and physician. She's the president of Spelman College. She's also a board member of the Bill & Melinda Gates Foundation and past director of the Foundation's program on HIV, Tuberculosis and reproductive health. She spent two decades with the Centers for Disease Control and Prevention, focusing primarily on HIV AIDS prevention and Global Health. 

So welcome and thank you for joining us today, Bill and Helene. I'd like to start with talking about some of the challenges we face in science communication. And as we've seen during the COVID pandemic, one of the big challenges is balancing reassurance with uncertainty. And before I ask you my questions, I'm going to play a clip of Dr. Tony Fauci speaking about this as part of the Nine Lessons series. So let's give that a listen. 

[Video clip from the Nine Lessons series begins to play] 

Tony Fauci: If you have a static situation with nothing changing and you get one opinion one day, and then a week later you change, that's flip-flopping. When you have a dynamic situation that's evolving week to week and month to month, as a scientist, to be true to yourself and to be true to the discipline of science, you have to collect data as the situation evolves, which almost invariably will necessitate your changing policy, changing guidelines, changing opinion. And that's exactly what happened with things like mask wearing. We didn't know until weeks and weeks into the outbreak that a lot of the transmission was by people who were without symptoms. It was that that made the CDC and all of us say, “We really don't need to be wearing masks.” As soon as we found out that, A, there was no shortage, B, we were getting good data, that outside of the hospital setting masks did work, and three, we found out that 50% of the infections were transmitted from someone who had no symptoms. When you put all those three things together, then the science tells us everybody should be wearing a mask. 

[Video clip ends]  

Céline Gounder: Bill, how did this play out in the smallpox eradication program, specifically this idea of scientific certainty, uncertainty, and science communication? 

Bill Foege: This is actually a balance that goes far beyond public health and medicine and almost everything we do. And on the one hand, you have to have enough certainty in order to get other people to follow you. There's a book by Gary Wills on Leadership, and it's entitled Certain Trumpets. He takes this from the Bible verse that says, “If you hear an uncertain trumpet, who would gird for battle?” 

So you have to have enough certainty. The other side of that though is Richard Feynman, the physicist who said, “Certainty is the Achilles heel of science.” If we believe something is true, we stop looking for other answers to why this is happening. And I think in smallpox, we always tried to present certainty in what we were doing. And all the time we worried about what could go wrong, what if we lose political support? I didn't see HIV coming, but boy, if I had, that would've been a big problem to deal with. 

Céline Gounder: Helene, don't you think public health officials should still be confident in expressing, particularly in an emergency, what we know and their recommendations for managing a public health crisis, and how do you balance that confidence and reassurance with the lack of certainty? 

Helene Gayle: So I think, and building on some of the things that Bill said, I think part of it is building the confidence in the communicator. And I think one of the things, and I point to Tony Fauci, is one of those people who I think Americans developed a sense of confidence with him because of his willingness and ability to say when we were wrong and what we know and when we knew it. And so I think recognizing that a lot of this is about building trust and building trust in the message as well as in the messenger. I think that's where some of the ability to be confident, letting people know that you're trying to give them the information as soon as you have it, but also being honest that this is evolving. 

A message is just a slice in time. And I think it's important that we remember that we're creating a narrative every time we open our mouths and thinking about what's the narrative that we're creating and being consistent in that narrative. So I think the consistency, building that trust, being able to say what you know and what you don't know is what really I think builds the confidence in the messages. I think what we saw through this pandemic as well, the COVID pandemic as well as past, are people who are unwilling to admit what they know and what they don't know, unwilling to go back and explain why we said something when we said it and why we're making that explanation of why we're now changing, as I think Tony Fauci did very clearly about mask wearing. 

So I think all of those things that really are about building trust and confidence are what can make us better in our communication as public health officials. 

Céline Gounder: So it still amazes me that the global health community decided to take on smallpox eradication. We often hear about sustainability, cost-effectiveness, those kinds of economic concepts. What does it mean, Helene, for a program to be sustainable? And when we say sustainable, for whom? 

Helene Gayle: Well, I think what we hope when we talk about sustainability is that efforts that are important for the short run can be sustained over the long run. And I think what we see so often in public health is that we have this massive surge of resources, personnel, effort, that then we let go of in between times. 

So each time we have a pandemic, we have to create this big surge all over again. What we need in public health is to be able to have that kind of long-term, sustainable approach, understanding that there will be times when we have to have those surges, but not letting everything go in between time. When you say for whom, it's really about how do we create a system and have a system that is in place that gets us not only at the times of great need and crisis, but is there for the public's health for the long-term. And that's what I hope we can move to as we think about public health in America and around the world. 

Céline Gounder: Bill, does that sound like that's a “sustainable goal” and should we be setting our public health goals based on what some think is sustainable or not? 

Bill Foege: Well, sustainability is a problem that I often had because people require evidence of sustainability before they'll fund something, but you don't know what is sustainable until you try and do it. One of the lessons that I learned in the seventies was, in this country, the appropriations for measles would go up when there were lots of measles cases and they would go down when cases were reduced. 

And inevitably, when they would go down, then the numbers had come up again. And so we had these variations. And we made a decision in the 1970s what would happen if we could interrupt transmission once, and that changes everything. Now the norm would be no transmission, and you could sustain the appropriations and it worked. We finally did that. So sustainability is something that bothers me. The pragmatists demand this, and I understand where they're coming from, but there was a fellow by the name of Harlan Cleveland who was an American diplomat. He was our ambassador to NATO for many years. And late in his life, he became interested in global health and he was astonished at what happened with so few resources. And he came to the conclusion that global health workers are fueled on unwarranted optimism. And I like that phrase, because that is in fact what we do, is we become very optimistic and we make something happen that could not have been foreseen, that it would happen. 

Céline Gounder: So this also reminds me about a conversation we had on the podcast with, believe it or not, a science fiction writer. Her name is adrienne maree brown, and we spoke with her about how she imagines world's, possibilities different from our own. So let's hear a short clip of that now. 

Where do you find the inspiration to think up, to dream up the world's that are so wildly different from our present reality? 

[Audio clip from episode 1 of the “Eradicating Smallpox” begins to play] 

adrienne maree brown: Saying that stuff is just the way it is. That's one of the greatest ways that those who currently benefit from the way things are keep us from even imagining that things could be different. For centuries in this country, we were told that slavery was just the way things are and that it could never be any different. And yet there are people in those systems who said, “This isn't right, this isn't fair. Something else is actually possible.” 

So a lot of the work of radical imagination, for me, is the work of saying, can we imagine a world in which our lives actually matter and we structure our society around the care that we can give to each other, the care that we need. 

[Audio clip ends]  

Céline Gounder: Bill, you just talked about unwarranted optimism and you told me once, in fact, I think more than once to bet on the optimist. But to go back to what you were saying about the pragmatist, doesn't it make more sense on some level to be pragmatic and realistic if you want to get things done? And how would realism have gotten in the way of efforts to eradicate smallpox? 

Bill Foege: Well, I think realism would have kept us from trying many things that we've tried. And the clip you just showed about an imagination that goes beyond realism is so important. If I would be director of CDC again, if I had a problem, I would try to get six comedians to come to CDC and I present them with the problem because they think in a different world than realism. And so I think it just makes sense to be unrealistic that we can do these things. 

Céline Gounder: Helene, what about you? How did you balance thinking big versus being pragmatic when you were leading public health programs over the course of your career? 

Helene Gayle: Well, I didn't bring in comedians, but I think maybe I missed the boat on that. I love that idea. I like to think that I was able to combine the two. I think if you don't think big, you will only achieve small progress. So I think you have to have big goals, but big goals can also be chunked into bite-sized pieces. So I think mixing the practical of what are the short-term games that are necessary to get to those big goals, both, give you a sense of what's pragmatic and possible, but also keeps you inspired towards the bigger goal. 

I think it's also the case in public health where oftentimes we are operating with very difficult political situations. And again, sometimes you have to be the realist and understand what the limits are, but at the same time not give up on what's your ultimate goal, what's your ultimate vision, and keeping that front and center, it's incredibly important, particularly as we think about how we inspire, back to the unwarranted optimism, how we inspire public health workers to keep going. People don't get inspired by the short term, “Did I get my stock in today?” They get inspired by, “I'm part of eradicating a disease or stopping a pandemic.” So I think we have to combine the two. 

Bill Foege: I might say that in India, we would have a meeting every month in the endemic states and go over what we had learned that month, and we would end the meeting by setting goals for the next month. We never once reached those goals until the last month. They were always beyond what we could do, but they gave us a vision of what we hoped we could do. 

Céline Gounder: So this also reminds me of another aspect of goal setting. In another episode of the podcast, we spoke with a global health expert, Dr. Madhu Pai at McGill University, and he pointed out that historically it's been white men in Europe and in the United States who've really driven the agenda in global health. Here's just a short clip from Madhu. 

[Audio clip from episode 2 of the “Eradicating Smallpox” begins to play] 

Madhukar Pai: We need to flip the switch and recenter global health away from this, what I call default settings in global health, to the front lines. People on the ground, people who are Black, indigenous, people who are in communities, people who are actually dealing with the disease burden, people who are dying off it, people who have actually lived experience of these diseases that we're talking about, having them run it is the most radical way of re imagining and shifting power and global health. 

[Audio clip ends]  

Céline Gounder: So Bill, who set the smallpox eradication goals? Was this local or global experts or both? Was it local communities and how were those different perspectives weighed and balanced in the program? 

Bill Foege: Well, the global goal was set by WHO. It was originally conceived by the Soviet Union and presented to WHO, and it got only three votes the first time. Later, when the Soviet Union and the United States combined their efforts, they were able to convince the World Health Assembly and WHO took this on. So the global goal was set by WHO, but countries had the ability to say no. And Ethiopia went for a long time not becoming part of the program, they had other priorities. And these are legitimate priorities that World Bank once had a discussion on whether we should get into polio eradication or not. And I agreed to be part of the debate, even though I hate debates. I agreed to be part because I wanted to know what were the strongest arguments against polio eradication. And for me, there were two of them. 

One was that this would distract from other global health efforts. People would focus on this. But the other one came from an African leader who said, “This is neocolonialism. You're telling us how to spend our money on a disease problem and not allowing us to make that decision.” My counter to that was, “I understand that, but I also understand when Gandhi said his idea of the golden rule was that he should not be able to enjoy what other people could not enjoy.” And so I said, “If I can enjoy the fact that my children, my grandchildren, and now my great-grandchildren are free of polio, I have an obligation as a parent to share that with everyone.” 

Céline Gounder: Helene, very often it's scientific experts, physicians, epidemiologists who really lead the goal setting. Is there anything wrong with this technocratic approach to public health goal setting, and isn't that just “following the science?” 

Helene Gayle: Well, it's obviously following the science at a macro level, but I think, while it's important to set these global goals and these big overarching goals, it's also very important to listen to the people whose health we're actually trying to have an impact on. And I can remember, during the HIV pandemic, where once people realized how important it was to mobilize resources, there was an unprecedented amount of resources available for HIV, and we got from several countries around the world, the pushback just as Bill was talking about, because they said, “Malaria is a bigger problem for me. We have more people who die from malaria, from measles, from other infectious diseases. So where are our resources for the things that are making the biggest difference for our people?” 

So I think it's great to set the global goals and to be able to have these big overarching goals, but we can't do that in the absence of also listening to the national and local needs and making sure that we're thinking flexibly about how we use our resources so that what we do really meets the greatest needs of people on the ground. 

Céline Gounder: Bill, you once quoted Einstein to me who said, “Perfection of means and confusion of goals seem, in my opinion, to characterize our age.” So are government officials and public health leaders somehow confused about public health goals while being overly focused on perfecting public health tools? 

Bill Foege: I think so. You can't stop scientists from trying to enlarge their area of knowledge. This is what scientists do. They try to figure out what is right and what is wrong. And so yes, we do confuse this. And it doesn't matter whether you're talking about a person, a state, a nation or the world, we devalue health until the day we lose it, and then suddenly it becomes so important. And so this idea of conveying what should happen ahead of time so we don't lose health is problematic. But yes, it's much easier to concentrate on the specifics and lose our sight of where we're actually going with this. 

Céline Gounder: Can you just give an example of this attempt to perfect a public health tool? 

Bill Foege: Well, with vaccines, you see that people keep improving the vaccines, but don't improve how to get them to everyone. The clip you showed on white people, mainly white men, making the decisions on global health in the past, is so true. And I've just finished reviewing the history of global health, and I think the one thing that was most destructive of global health was colonialism. Some people try to justify it on the basis of it brought new science and so forth, but just think of this country and the fact that colonialism killed off so many people that the slave trade became so important. 

And so today, we're still operating with the effects of colonialism in this hemisphere. Not seeing the vision of the big goal and concentrating on small things, it's easier for all of us to do. 

Céline Gounder: Helene, do you agree that public health officials are confused about the goals? And if so, why and how? 

Helene Gayle: Well, I think it's hard to talk about public health officials as a monolith, and it's part of the challenge, particularly in this country, is that we have such a disjointed public health system. And I think we would benefit from having a much different public health system, such that people can individualize their roles, what they want to focus on, et cetera. But at a national level, and I would argue even at the global level, that there is a system that is consistent about what's most important and what's most important to deliver on. 

So I do think that there's a lot of inconsistency in our system. I think we have a fragmented public health system, and we would really benefit by having something that really had a much more of a network that is coordinated than what we have today. 

Céline Gounder: I just got back actually from vacation in Morocco and I happened to be staying in the Medina in Marrakesh the night of the earthquake. And it's now been estimated that nearly 3,000 people have died in that earthquake or from that earthquake, to date. I felt it, but the building where I was staying sustained hardly any damage. And to date, I haven't heard of any tourists or expats having been reported dead or seriously injured. Now, this was not an infectious disease outbreak, but it is a public health crisis of a kind, and some are more likely to be hurt and die than others. What does this tell us about, Bill, how to build resilience into the system and how was this done in the context of smallpox? 

Bill Foege: Well, the resilience is a difficult thing because we think locally. Well, wherever you are in the world, you're both local and global. So I keep telling students, wherever you're working, you're working on global health. And so start thinking that way of how do we incorporate all these people. And see, you're absolutely right. It doesn't take an infectious disease. It takes a disaster to show what the social problems are that are causing this. Michael Osterholm once said, “One of the best fire departments we have is at the Minneapolis airport.” He said, “If we go 10 years or 15 years without a crash, no one will reduce their budget.” This is the kind of resilience that we need in public health. The last appropriations hearing that I had as director of CDC was chaired by Senator Hatfield from Oregon. He was the chair of the entire Appropriations Committee, but he asked permission, as a favor to me, to actually share this last one. 

He asked me a question that I was not expecting, which is the one you just asked. He asked, “If you were in charge, how would you improve the sustainability of public health?” And I told him that there were three things I would do. Number one, I would identify any program that has a positive benefit cost ratio, that is, for a dollar invested, you save more than a dollar, plus you improve health. Because if you don't do that, you're agreeing to spend money and have the disease both. And I said, “If you took these programs,” and I said, “In order to avoid infighting between the Congress and the executive branch, I put this totally in charge of Congress.” You decide when a program has a positive benefit cost ratio. And now it doesn't compete with other things in the budget, it becomes something that's an entitlement. We need this because it is cheaper and it improves health. 

Number two, I said, “I would index public health to healthcare expenditures, because the ratio of public health to healthcare keeps going down every year.” I said, “I would accept whatever it is right now and say we have to index our public health spending to that.” 

And the third, I would come up with mechanisms to improve and reward programs that benefit outcomes. Today, we benefit access and process, but not outcomes. And so, if we could benefit outcomes, it would change the way the insurance companies work and other programs work. So those three things I think would provide sustainability and public health we don't have now. 

Céline Gounder: Helene, how was resilience built into the system in the context of HIV and or TB? 

Helene Gayle: I'll answer that in a minute, but I just want to add on and taking from the example that you gave from Morocco that I think in many cases we're talking about sustainability and resilience, but we're also talking about equity. At the end of the day, the reason you probably were less likely to get impacted was you were probably staying in a building where the construction had been done in a way that it was as sustainable and not prone to the conditions of earthquake. And the people who are likely to have lost their lives were probably living in substandard building situations. So I think every time we think about sustainability and resilience, we also have to think about equity and are we making sure that the way in which we design our programs take equity into consideration, because that's ultimately what is going to make populations and people have the kind of resilience that's necessary. 

I think when I look at the programs like tuberculosis and HIV, I think what we tried to really do was to build up systems as we went along, because the best way to make sure that our efforts were sustainable and had resilience built into them was to actually build systems, not just focus on the program or the effort that we were doing. 

So in HIV, clearly when I look back on the public health infrastructure that was built, the human capacity that was developed as a result of HIV, that's what starts building in resilience because you're not just building for the HIV pandemic, but you're really using those dollars in ways that can help to strengthen systems. And that's what I think we have the kind of resilience and sustainability that we're talking about. 

Céline Gounder: Lately, I've been thinking a lot about this concept of “Wicked problems.” And for people who are not familiar with this term, it goes back to the management literature several decades ago. And these are complicated, they're messy, they're context specific problems. People may not agree that there is a problem or what the problem is, they disagree on what caused it. And with wicked problems, there's no one right solution, just some that might be less bad, might often create new problems. And so, these are very much about values and not just science. Bill, how would you apply this idea of wicked problems to public health challenges like smallpox or COVID? 

Bill Foege: Well, wicked problems turns out to be a good expression of, a great picture of this. And when I think of vaccines, for instance, in the beginning, in 1796 of the smallpox vaccine, and how they've improved in numbers and types, when I was born, my baby book shows I have got only two vaccinations. Children today will get 18 or 19 or 20 different vaccinations. And you look at the future of this, we now have two vaccines against cancer, one against liver cancer and one against cervical cancer. We're going to see more vaccines against neoplasms. You look at the possibility of having vaccines in the future for certain heart diseases or even for addiction, alcoholism and drug addiction, and the possibilities are so great. And yet at the same time, we have more and more people who don't trust science, don't trust government, and they become anti-vaxxers. 

So this is the real challenge of vaccines. It will continue to be the foundation of global health, but we have to figure out how to get people incorporated in the solutions. Vashon Island in Puget Sound had a reputation for very low immunization uptake, and many of the people on the island were the hippies of the sixties and they didn't trust government and so forth. The New York Times actually had a front page article on the rate of immunization in children, and I think about 19% were not being immunized. 

Now, they would not listen to the health officers of Seattle or anyone else of authority coming in, but two parents who had been Peace Corps volunteers started their own program of finding out from people what would it take for you to change your mind. What is it that you don't know that you wish you knew? The vaccination rate decreased from 81%, or increased from 81% up to 88%, 89%. They were doing something at a grassroots level that we could not have done from the top down. And so, there are solutions to wicked problems, but they sure do require energy and organization and the ability to respect culture. 

Céline Gounder: Helene, is there a way we can better align people who have different sets of values around some of the same public health goals or strategies when it comes to some of these wicked problems, whether that is COVID or some of the other problems facing us today, whether it may be climate change or disinformation. Bill mentioned some of the challenges with anti-vaxxers and anti-science. 

Helene Gayle: Well, this is another time where I think we should bring in the comedians, but I do think, maybe not the comedians, but to take a point from what you were saying earlier, Bill, I do think looking at how do you find the common ground? And sometimes there's only 5% of common ground, but you can start with that and continue to grow from there. I think oftentimes, we approach these things that are adversarial in a counter adversarial way. So if somebody's hostile, we up the hostility, instead of thinking, “All right, where can we find common ground? What are the things that we all agree upon?” 

And sometimes it's just the simple fact that we agree that saving lives is a high value and you can start from there and begin to develop the proof points that make nonbelievers believers. So I think we don't do enough of thinking about where we find common ground, and instead, go to our corners and think by continuing to insist on what we believe and think that that's what's going to convince people, versus starting from where we all have a common belief and building from there. I don't know any other way to do it. It's not a magic bullet. It won't work all the time. But I also think there has to be a point at which you recognize there are some people who you will never get on your side, and if you continue to try to wait for that to happen, you'll get stuck and not move forward. 

So there's always a certain point when you just need to keep moving forward, understanding that if you demonstrate effectiveness, that may be the most likely way of bringing others along. 

Bill Foege: When I've had an opportunity to meet with anti-vaxxers, I always start with the fact that I know no parent does this, withholding vaccines, to hurt their child. 

Helene Gayle: Exactly. 

Bill Foege: They do it only because they believe it's the best thing for their child. And so if you can start there, you're in a different position than if you just say, “Well, don't you read the literature? Don't you listen to…?” So I think understanding that there's a reason why people feel this way is the beginning. 

Céline Gounder: So earlier we were talking a bit about public health tools and this desire to perfect public health tools, but at the same time, innovations in medical technology were in fact key to eradicating smallpox, especially a simple little tool called the bifurcated needle. Here's a clip of some smallpox eradication workers discussing this tool from episode four of the podcast. 

In the early 1970s, smallpox was still stalking parts of South Asia. India had launched its eradication program more than a decade before, but public health workers couldn't keep up with the virus. Enter the bifurcated needle. 

[Audio clip from episode 4 of the “Eradicating Smallpox” podcast begins to play] 

Tim Miner: It was a marvelous invention. In its simplicity, it looks like a little cocktail fork. 

Céline Gounder: You dip the prongs into a bit of vaccine. 

Tim Miner: And you would just prick the skin about 12 or 15 times until there was a little trace of blood, and then you'd take another one. 

Céline Gounder: It barely took 30 seconds to vaccinate someone. And it didn't hurt. 

Yogesh Parashar: No. 

Céline Gounder: Well, it didn't hurt too much. 

Yogesh Parashar: It was just like a pin prick rapidly done on your forearm. You had a huge supply with you and you just went about and dot, dot, dot, vaccinated people. Carry hundreds with you at one go. 

Tim Miner: And you could train somebody in a matter of minutes to do it. 

Céline Gounder: Easy to use, easy to clean, and a big improvement over the twisting teeth of the vaccine instrument health workers had to use before. The bifurcated needle was maybe two and a half, three inches long, small but sturdy enough for rough-and-tumble field work. 

Yogesh Parashar: It was made of steel, and it used to come in something that looked like a brick. It was just like one of those gold bricks that you see in the movies. 

Céline Gounder: And maybe worth its weight in gold. 

[Audio clip ends]  

Céline Gounder: So, Bill, public health officials say, in the context of COVID, that we now have the tools to diagnose and treat and prevent COVID, but are these tools enough for us to declare victory over COVID when not everyone has access to those tools? And in the context of smallpox, how did non-biomedical tools compliment biomedical innovations like the bifurcated needle? 

Bill Foege: Well, going back to what Helene said, we have to be thinking of this globally and everyone and realize that these tools for smallpox, that is the vaccine, at least some way of giving it, existed long before WHO decided to have a program. But the people that were getting smallpox were the ones who were disenfranchised. They were the ones who were unemployed, in poverty, who had bias, that sort of thing. And so, it was very important to include the non-technical things. And in smallpox, I can tell you that every school and every church and every chief of a village and every volunteer that became involved was part of the solution of this. 

Now, on the other hand, I can't quite give up on smallpox eradication, even now, 40 plus years later. And I keep thinking of ways we could have improved. Nowadays, I would train dogs to pick up the scent of smallpox, because sometimes you would have beggar communities, people actually at the railroad station covered with a cloth with smallpox, but nobody knew that, but a dog would've picked that up right away. I've even come to the conclusion, if we were well enough organized, we could get rid of smallpox without vaccine and without the technical tools, the bifurcated needle, the jet injector and so forth. You would simply get people who are sick with smallpox and you would isolate them immediately and then you would follow all of their contacts. And the first symptom in a contact would get isolated and so on. And if you were organized well enough, you could get rid of smallpox without vaccine. So the tools are very important, but they're not the last word. 

Céline Gounder: Well, and in fact, that's the approach that was used for Ebola. And now we have a vaccine. But most of the Ebola control efforts during the West African epidemic were really about that, identifying and isolating. 

Helene, are we overly reliant on biomedical tools? And if we are overly reliant, should we pave the way for greater use of non-biomedical tools? 

Helene Gayle: Well, as we know, the social determinants of health contribute more to health status than access to healthcare itself. So access to healthcare, including all the biomedical advances is necessary but not sufficient. I think we have to continue to think about why do we have some of the gaps in health that we know already exists. We look at the COVID pandemic as an example, where we know that the populations that were at greatest risk outside of age are people who lived in houses that were overcrowded or who had jobs that put them at risk, low wage earners, et cetera. So I think we have to think about both things. And I think back to your earlier question that is about people's trust and mistrust, part of the trust in people being willing to access some of our biomedical tools comes from feeling that the rest of their needs are also being taken care of. 

So if we just think of populations as we've got these great tools and we are going to give you these tools when your greatest challenge is whether or not you're going to be able to feed your children at night or whether or not you're going to have a roof over your head, you're not going to be as eager and the uptake of our biomedical tools will not be as great. So I just think it's about combining both and making sure that we're thinking about some of these root causes that will also be part of helping to enhance, focusing on those will also be part of enhancing people's trust and belief in some of the other approaches, that biomedical approaches that we know also make a huge difference. 

Céline Gounder: Public health is different from clinical medicine, in that it focuses on the public or the ‘we' so to speak, while clinical medicine focuses on the ‘I' or the patient. There seems to be very little appetite in this moment for thinking about the ‘we.' 

Bill, is there anything wrong with that? And if so, how do we shift that perspective that thinking about ‘we' and public health and beyond? 

Bill Foege: People often say clinical medicine deals with the numerator, the people that come to clinics and hospitals for care, while public health deals with the denominator. That's simplistic because the denominator includes the numerator. And so, public health really is concentrated on everybody, on the ‘we' and how to get everybody together on this. 

There are two things from history that always impressed me. Confucius was asked by a student once, “Could you tell us in one word how best to live?” And Confucius said, “Is not reciprocity that word.” And so, this is ‘we' that everybody's dealing with each other. And then Gandhi said, his idea of the golden rule was that he should not enjoy something not enjoyed by everyone, the ‘we.' 

So we keep hearing this from the wise people of history to stop thinking about just ourselves. Gandhi also said, “We should seek interdependence with the same zeal that we seek self-reliance.” And then he added in a soft voice, “There is no alternative.” And this is true. There is no alternative. And we've just got to take that approach in school, that's much of school is built around how to improve your self-reliance, how to develop, how get money in the future and so forth. And we have to figure out how to teach interdependence. 

Céline Gounder: Helene, should we be moving from an ‘I' to a ‘we' framing? And if so, how do we do that? 

Helene Gayle: I think we have to. I think we recognize, and when we have pandemics, it's very obvious. You can't just think about what's happening to you as an individual without recognizing that if we don't stem transmission for something like a COVID, all of us are at risk. 

So I think this sense of reciprocity is critical as we think about it. And it's more broadly in our society. We can't think that crime happens in one part of the city and it won't also impact our economy, the economy of the city overall and ultimately impact other neighborhoods. I think we continue to think that we can wall off problems when we have to realize how interconnected we are, whether it's health, whether it's our economies, whether it's the issue of climate change. I think as a species, we're at a point where the ‘I' thinking is having huge impacts for all of us. And unless we start having that ‘we' mindset, we really are not going to be able to tackle some of these difficult wicked problems. 

Bill Foege: If I could add one thing that Will Durant once said, ‘We will never do things globally unless we fear an alien invasion.” And what we've come up with are surrogates for alien invasions. So we see nuclear weapons as threatening of all of us. So we think ‘we.' But there are other things. Our synthetic biology might be another one of these. Climate change may be a third one. We have four or five things that could totally eliminate people and we should be thinking ‘we' in order to solve those problems. 

Céline Gounder: So I'm now going to shift gears a little bit and take some of the questions our audience has been sending in. The first comes from Paurvi Bhatt who asks, “As we try to deal with new pandemics and eliminate older ones, how can we balance attention spans, science and safety in a world where “failing fast” and disruption define how we think about innovation?” 

Helene, do you want to take a stab at that one? 

Helene Gayle: Well, I just think we have to stay the course and continue to find ways. And we started out talking about health communications. I think we need to get better at our communications and in keeping people engaged in issues, because we are living in this 24/7 news cycle and a new issue coming up all the time. I think we as health professionals have an obligation to make sure that we are keeping these issues that are front and center in people's minds and continuing to share what progress is happening. I think when people recognize there's progress and you're not just telling the same old story, I think you can keep people engaged, but I think it's on us to do a better job in that regard. 

Céline Gounder: Bill? 

Bill Foege: I tell students now, and it took me a long time to reach this conclusion, that whenever they're faced with these big problems, to think of three things. 

Number one, try to get the science right. We've talked about you can't always do that and you have to apologize and go back, but try to get the science right. 

Number two, add art to the science. Will Durant says, “The first scientist that we know by name was Imhotep in Egypt, who was a physician and an artist and designed the step pyramid.” Because he said, “Then you get creative common sense at its best.” It was Huxley that says science is simply common sense at its best. So you get creative common sense at its best. 

And then I go back 700 years to Roger Bacon who did a report for the Pope. And he said, “One of the problems with science is it has no moral compass.” And so you have to develop scientists with a moral compass. And when you do this, now you have moral creative common sense at its best, and this is a great approach to wicked problems. 

Céline Gounder: Is public health science with a moral compass? 

Bill Foege: It's supposed to be. And sometimes we see it drifting off, but in general, public health people have a social mind that they're trying to do this with a moral compass, including everyone. 

Céline Gounder: Our next question comes from Merina Pradhan. Can you touch upon how the message needs to be as simple and brief as possible? Dr. Fauci's message was very on point from a public health point of view, but how many in the general population would be able to assimilate that? Helene? 

Helene Gayle: I would just say we have to tailor the message to the audience. When I saw the background that Dr. Fauci was talking against, I think he was talking to an audience of people who could incorporate that message. I might be wrong, but I think regardless, the point is if you're sitting and talking to a group of public health professionals, you have one message. If you're talking to the general public, you have another. 

And I think it is true that we sometimes get confused with our own language because there's so many nuances to public health that we put out these messages, that by the time we're done, it's hard to know. Do you believe yes, or do you believe no? So I agree. I think we have to keep it simple, but I think we also have to keep it truthful. And sometimes that's a real challenge with the nuances of public health messaging. But I think again, tailoring it to the different audiences and recognizing that hopefully you have more than one bite at the apple, if you will, to make it short and concise, but then have other opportunities where you can explain it in greater detail. 

Céline Gounder: Bill, this question is for you, from Mark Rosenberg, one of the new epidemics is the public health crisis of gun violence, now the leading cause of death for children and teens in the United States. Are there lessons from the eradication of smallpox that could be applied to help solve this new epidemic? 

Bill Foege: I think all of the lessons from smallpox, knowing the truth, having coalitions, making sure that you progressing in the right way, having respect for culture, all of these things do apply. But I would end that answer, with becoming better ancestors, we're saying that the ultimate expression of love from any of us is to become a better ancestor. And we certainly can do better on gun violence. And don't put up with the discussion that says this is due to mental health problems and this and that, when other countries don't have the same problem and they have just as much mental health problems as we do, but they don't have the guns available. 

Céline Gounder: Helene, this is a question from Ayo Femi-Osinubi. “Bill mentions that we don't know what is sustainable till we try. How would you approach sustainability for pandemic preparedness in the midst of trying to prioritize basic health service delivery?” 

Helene Gayle: Well, I think that the two aren't necessarily in opposition. I think we need to have basic health services and building on basic services, making sure that we are thinking about how are those services available and sustainable so that when we have crises, public health crises, those systems are there and functional in a way that allows us to ramp up for public health emergencies. 

So I think those things are not in opposition. It's what I was talking about earlier. I think we need a more clear and comprehensive public health system that doesn't just get ramped up every time we have a crisis, that it's there, that it's stable, that we have the kind of workforce that we need, that we have the kind of tools that we need, and that those are in place and that we build upon those than the other services that are important for individual care. 

So again, I go back to a lot of this is about how we build systems that can be sustained and that are flexible and nimble so that they can respond when we have these public health crises. 

Céline Gounder: So one last question. I'm going to give this one to Bill from David Torres. “I teach my global health students about the history of smallpox eradication. Given the coercive nature of the final push to vaccinate some people for smallpox and today's resistance to and mistrust of public health measures, including vaccination campaigns and masking for COVID, would the elimination of smallpox be conceivable today? And if so, how would it be accomplished?” 

Bill Foege: It would be very difficult today because of HIV and not knowing about immune systems, but you could still do it. The question about coercion, we hear this often, and most of this comes from one paper by Dr. Greenough, where he has interviewed people who worked on smallpox who used coercion. They would break into huts at 2:00 in the morning with the police officer to do that. None of that was necessary. 

And so particular people were so enthusiastic about smallpox eradication that they did this. But think about it for a moment. If you have a village with three people who have refused vaccination, if they get smallpox, everyone around them is already vaccinated. They're the ones that suffer. You don't have to go in and use coercion. And so, when I've talked to other people who worked in smallpox, they're surprised that anyone used coercion. You don't have to do that, and that's part of respecting the culture, is that you find other ways to do this. 

Céline Gounder: Well, I really want to thank both of you, Bill and Helene for joining us today and for answering all of my questions, the audience's questions. Between the two of you, you have over a century's worth of wisdom in public health, and I always love hearing what you both have to say about these issues. 

I just want to remind the audience that a recording of the event will be posted online later today and that all registrants will be sent an email when the recording is available. Also, please check out the podcast, Epidemic. It's available on Apple, Spotify, wherever you get your podcasts. Season two is the season on eradication of smallpox. And also check out the Nine Lessons at ninelessons.org. And thanks everyone for joining us today. 

Helene Gayle: Thank you. 

Bill Foege: Thank you. 

Season 2 of the ‘Epidemic' Podcast Is ‘Eradicating Smallpox'

The eight-episode audio series “Eradicating Smallpox” documents one of humanity's greatest public health triumphs.

By the late 1960s and early 1970s, smallpox was gone from most parts of the world. But in South Asia, the virus continued to kill. Public health heroes had to conquer social stigma, local politics, and more to wipe out the 3,000-year-old virus, an achievement many scientists thought was impossible.

Host Céline Gounder traveled to India and Bangladesh and brought back never-before-heard stories, many from public health workers whose voices have been missing in the coverage of the history of smallpox eradication. Gounder brings decades of experience working on tuberculosis and HIV in Brazil and South Africa; Ebola during the outbreak in Guinea, West Africa; and covid-19 in New York City at the height of the pandemic.

Season 2 of “Epidemic” is a co-production of KFF Health News and Just Human Productions.
