Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said Thursday new data on Pfizer's Covid-19 vaccine is encouraging but doesn’t mean the company's vaccine is better than the other Covid-19 vaccines authorized for use in the US.
Earlier Thursday, Pfizer announced that ongoing Phase 3 clinical trials of its vaccine confirmed that protection against Covid-19 lasts at least six months after the second dose.
The vaccine also appeared to be fully effective against the virus variant first identified in South Africa, B.1.351.
When asked by CBS’s Gayle King if that meant Pfizer's vaccine is better than other Covid-19 vaccines, Fauci said “It just means they did a test, and the results of the test, as you mentioned Gayle, are really very encouraging...Something that we suspected all along, that even though you don’t have a vaccine directed specifically against the variant, you can get some pretty good protection.”
He said that Pfizer had done the study, and it looked really good. He noted he “would not be surprised at all” if Moderna and other vaccine companies got similar results if they did the same thing.
