Covid Vaccine Booster Gives Effective Antibody Protection Against Omicron
The study found that in people who had received the Pfizer vaccine for all three doses, antibody levels against Omicron after a third dose were similar to those previously reached against Delta after only two shots.

A third dose of COVID-19 vaccine increases the level of antibodies that can effectively neutralise the Omicron variant of coronavirus, according to a study published in The Lancet journal.
Researchers from Francis Crick Institute and the National Institute for Health Research (NIHR), UK, found that antibodies generated in people who had received only two doses of either the AstraZeneca or the Pfizer vaccine were less able to neutralise Omicron as compared to Alpha and Delta variants.
They also found that antibody levels dropped off in the first three months following the second dose but a third 'booster' dose raised levels of antibodies that effectively neutralise the Omicron variant.
