The globe’s best bet at managing Covid-19 demands a global effort. At the moment this looks like the Covid-19 Vaccines Global Access (COVAX) Facility, which pulls together the buying power of most of the world’s countries and aims at fair access to the eventual vaccine. It does this by using the pooled funds of participating countries to invest in vaccine candidates. With COVAX’s volume guarantees, manufacturers would be better able to continue their work and scale up the most promising vaccine candidates.
