Pfizer Says COVID Booster Offers Protection Against Omicron

Pfizer reports that three doses of its COVID-19 vaccine may neutralize the Omicron variant, with a third dose significantly boosting antibody levels. The CDC notes that 47 million Americans have received booster shots. President Biden called this development exciting. However, the findings are preliminary and not yet peer-reviewed. Concerns remain about the rapid spread of Omicron and ongoing Delta variant surges, especially in the US. Booster shots are currently approved for those 18 and older, with Pfizer seeking FDA approval for 16-17 year-olds. The US is experiencing increased COVID-19 cases, hospitalizations, and deaths, with some states breaking records for hospitalizations.
