Fauci Sees Covid-19 Vaccines For Different Patients With Five In Final-Stage U.S. Trials

With four vaccines against Covid-19 in the final stage of U.S. clinical trials and a fifth on its way, Dr. Anthony Fauci sees the potential for vaccines to hold promise in some patient populations better than others.

Fauci said late last week he remains optimistic about vaccines in their final stage of development and he believes Americans will begin to be vaccinated in November and December. And as vaccines are approved, researchers may find that one works better on one population than others.
