GAVI CEO ON GLOBAL VACCINE EFFORT — As 2022 gets underway, health advocates across the world are preparing to ramp up the global vaccine campaign to reach the World Health Organization's goal of inoculating 70 percent of the world's population by July. Seth Berkley, the CEO of Gavi, the vaccine alliance and a leader of COVAX, the global vaccine equity effort, spoke to Global Pulse about preventing new, more-transmissible coronavirus variants this year. (The interview has been edited for clarity). What conversations are you having with colleagues at COVAX about how the first part of 2022 will look for global supply and vaccine readiness? What steps is COVAX taking to tackle these issues? We will, in the next week or so, announce that we've delivered a billion doses. We've allocated 1.6 billion; 1.4 billion were allocated in 2021, of which 1.2 billion were to the COVAX [Advanced Market Commitment] 91 poorest countries. Our original goal was 950 million. I'm not going to argue with anybody else that that is enough. But now, as we look at where we are in the beginning of 2022, supply is improving dramatically. We dramatically increased the number of doses going to countries. In December, we did over 300 million doses. There are between 20 and 25 countries that have been problematic on absorption, capacity and delivery. And those are getting special attention and will continue to get special attention to try to make sure that they can increase the amount of vaccine they can use and do it in a way that gets them to their own goals. Some countries have been able to absorb all the doses and scale up very dramatically during this period, places like Rwanda and Vietnam. What is COVAX doing to make sure low- and middle-income countries across the world get more shots in arms in 2022? Lots of different vaccines are making up the supply that is coming in now. And that's on top of the donations. So one of the things we're trying to manage is to get countries to have the right vaccines for the right place. You might say with capital city health care workers, Pfizer is easier to use. You might say, in the periphery, you want a temperature-stable vaccine that has a long shelf life and that might be an AstraZeneca or Novavax. You might say that in a refugee area, or an area that has instability, you want to use a Johnson & Johnson as a single dose. How is COVAX factoring Novavax into the 2022 supply calculation? [Novavax] took longer to come out. And the question now is, since it did come out late, what will the acceptance rate be? Will there be demand for it? What we'll have to do is make sure that countries are educated. We're beginning to see a lot of demand in European countries for this vaccine, which is sometimes used for boosters. It's been a very effective booster. How will continued booster campaigns and potentially fourth doses impact the race to get primary doses to low- and middle-income countries in 2022? Right now, there's no evidence that fourth boosters are required anywhere. When you talk about world production, from a public health perspective, the first priority is trying to get the high-risk groups covered around the world so that we can prevent severe disease and death and also reduce the overall spread of infections. The question that will have to be answered in 2022 is: Do you want to try to continue to vaccinate with these vaccines against infection versus severe disease and death? And if so, it is likely, though I can't say definitively, that it will require specialized variant vaccines. Once we move down that pathway, there is a worry that we end up with an inequality 2.0 where companies will want to provide those vaccines to high-income countries and not necessarily across the world. Will 70 percent of the world's population be vaccinated by July 2022? The U.S. goal is 70 percent by September. I know the World Health Organization has a goal to do it midyear. The critical issue there is that [that number] is a kind of a global aspirational goal. The critical issue is what does each country want? At the end, we will serve what the countries want. Right now, we have supply for about 40 percent of the population. And obviously, that'll depend upon what one wants. In terms of the number of doses that will exist in the world, it is possible in terms of what we have visibility on. But at the end of the day, we don't know what's going to happen with Omicron, boosters, new variants, manufacturing problems, etc.
