News Alert: Moderna booster shot increases antibody levels against Omicron, company says
  Biotechnology company Moderna announced Monday that preliminary data suggests its half-dose booster shot increased antibody levels against Omicron compared with the levels seen when a fully vaccinated person does not receive a booster -- and a larger-sized dose of the booster increases antibody levels even more. Currently, Moderna's booster is administered as a 50-microgram dose. The company announcement noted that its 50-microgram booster dose increased antibody levels 37-fold and a 100-microgram booster dose increased antibody levels 83-fold compared with levels seen before a booster. It remains unclear what these increases mean as far as how well the booster doses clinically work against Omicron.
