E-Mail Washington, D.C. - June 9, 2021 - The Pfizer COVID-19 vaccine is protective against several SARS-CoV-2 variants that have emerged, according to new research presented in the journal mBio, an open-access journal of the American Society for Microbiology. While this is good news, the study also found that the only approved monoclonal antibody therapy for SARS-CoV-2 might be less effective against SARS-CoV-2 variants in laboratory experiments. "The vaccines provide very strong protection against the earlier forms of the virus as well as the newer variants. This is an important point because I have heard people say that they don't think there is a reason to get vaccinated, because the vaccine isn't going to work against the variants, but that is not true--the vaccine will work against the variants," said Nathaniel "Ned" Landau, Ph.D., professor in the Department of Microbiology at the NYU Grossman School of Medicine, in New York City.
