Several next generation Covid vaccines are now advancing into mid- or late-stage trials. So this month, I have started a new section—a watchlist of featured vaccines that are both at more advanced stages of development, and reporting ongoing recent progress. I highlight 3 vaccines in particular—from Japan, South Korea, and the US—with a further 6 included in the watchlist. I hope this focus on advancing vaccines will make the progress in next generation vaccines clearer. The post begins there.
