Who should get the Covid-19 vaccine first? Ethicists are fiercely debating how to vaccinate billions of people

Pfizer and Moderna have discovered effective vaccines, but some of us will get the shot before others.

It’s great news, but there’s a problem. For a while, there won’t be enough of any vaccine for all the people around the globe who want to get it. So who should get access to the first doses?

One way to answer that question is to say: The nations that discover a vaccine — or that can pay those who discover it — get first dibs. All the other nations just have to wait until more doses can be manufactured.
