Pfizer says booster dose of vaccine protects against omicron variant
after their initial two-dose Pfizer or Moderna series or two months after the single-dose Johnson & Johnson vaccine.
Pfizer is the first vaccine maker to release test results against omicron, although Fauci projected that there's"no doubt" that a third shot of Pfizer's or Moderna's vaccine or a second shot of Johnson & Johnson's vaccine provide"optimal protection" against the virus. Will a significant number of fully vaccinated, but not boosted, people turn up in hospitals, infected with the omicron variant?On Tuesday, a South African research institute also released lab results on, showing about a fortyfold reduction in vaccine-induced antibodies that could neutralize the new variant. That study didn't look at booster shots, however.
