The U.S. Food and Drug Administration has authorized the usage of a COVID-19 booster vaccine dosage made by Moderna and Pfizer-BioNTech.
The Centers for Disease Control and Prevention (CDC) has issued an advisory recommending updated booster shots for teens to fight against the recent Omicron variant surge. A day earlier, the U.S. Food and Drug Administration also authorized the usage of a COVID-19 booster vaccine dosage made by Moderna and Pfizer-BioNTech.
The booster dose falls in category of bivalent vaccines, which offer protection against two viruses or two different strains of the same virus. In this case, the booster COVID-19 vaccine greenlit by the CDC contains messenger RNA (mRNA) components of the original strain of SARS-CoV-2 as well as the BA.4 and BA.5 strains of the Omicron variant that has been wreaking havoc lately. The recommendation comes months after the Vaccines and Related Biological Products Advisory Committee voted to add an Omicron component to COVID-19 booster vaccines.
