The immune response to COVID-19 helps protect against reinfection, but that protection is weaker against Omicron than it was against earlier variants of the coronavirus, according to new data. In other news, protection provided by booster shots of the mRNA vaccines from Moderna Inc. or Pfizer Inc. and partner BioNTech SE starts waning quickly, according to data published in Feb. 11th’s Morbidity and Mortality Weekly Report from the U.S. Centers for Disease Control and Prevention (CDC).
