Dr. Anthony Fauci speaks about the Omicron coronavirus variant during a press briefing at the White House in Washington, U.S., December 1, 2021.White House chief medical advisor Dr. Anthony Fauci on Friday said lab studies strongly suggest that booster shots will give you cross protection against a "wide range" of Covid-19 variants, but noted it has not been proven yet.
Booster shots "markedly" increase antibody titers against variants of the virus, Fauci said at a White House press briefing Friday. Third shots also increase so-called memory B cells and T cells,Memory B cells create antibodies to fight bacteria and viruses, while T cells target and destroy other cells infected with a virus.
"There's every reason to believe that if you get vaccinated and boosted that you would have at least some degree of cross protection," Fauci said. "Very likely against severe disease, even against the omicron variant."The variant has some 50 mutations, more than 30 of which are on the spike protein, which is the mechanism used by the virus to attach to human cells.
