Great news! With the threat of a new wave of COVID-19 coming, the Food and Drug Administration (FDA) has just signed off on two new booster shots, one from Moderna and one from Pfizer/BioNTech. The mRNA vaccines have been updated to teach the body to fight the XBB.1.5 Omnicron subvariant of the coronavirus and other closely related strains that are circulating. The Advisory Committee on Immunization Practices will make recommendations for their use—they are scheduled to meet tomorrow. After the CDC director signs off on those recommendations, the vaccines can be administered. Therefore, they could be available in pharmacies in just a few days.
