Overview
On December 11, 2020, the F.D.A. authorized Pfizer's vaccine for emergency use for the prevention of COVID-19. Since then, many other vaccines have been developed, such as the ones from Moderna, AstraZeneca, Janssen, Sinovac, Sinopharm and Gamaleya. Efficacy, side effect and safety profiles vary dramatically between them, as they are produced using different mechanisms.
