Pfizer says a third dose of Pfizer vaccine neutralized the Omicron variant in lab tests. The two dose was much less effective at blocking the virus. A third dose increased antibodies 25 fold compared two doses for the omicron variant. Pfizer CEO Albert Bourla says- "Although two doses of the vaccine may still offer protection against severe disease caused by Omicron strain, it's clear from these preliminary data that protection is improved with a third dose of our vaccine."
