With a surplus looming, how should the US use excess vaccines?

Amid growing calls for the US to mitigate a global shortage of COVID jabs, the US grapples with Russia and China’s influence.

With the United States racing towards its goal of having enough coronavirus vaccines available for all adults in the country by May 1, the debate over what it should do with excess supplies is intensifying. The US is projected to have a hefty surplus of coronavirus vaccines in the second half of 2021, estimated at about 600 million excess doses, but the administration of President Joe Biden has offered little insight into how those shots will be allocated. Global health advocates have said the shots could be used to help ease a global supply shortage, which is partly the result of production problems but also caused by some wealthy countries procuring vast quantities of vaccines from pharma companies.
