Report: FDA to approve booster shots within 48 hours

The US Food and Drug Administration (FDA) is expected to announce within the next 48 hours that it is authorizing COVID-19 vaccine booster shots for some people who are immunocompromised, CNN reported on Wednesday, citing a source familiar with the discussions.

This would be a third shot of the current two-dose Pfizer and Moderna vaccines. That announcement could slide, the source cautioned, but this is the current timing.
