When Will The Newly Updated Omicron COVID-19 Vaccine Be Available?

In an effort to keep up with the emergence of new COVID-19 strains, the U.S. Food and Drug Administration (FDA) announced in a press release on August 31, that they have issued

emergency authorization for the use of both Pfizer and Moderna's "updated booster." As a bivalent vaccine, the formula contains mRNA components of the original strain of COVID-19,

as well as components shared with the BA.4 and BA.5 Omicron subvariants. By combining formulas, the updated boosters now contain elements of the original vaccine, in addition to

elements specific to Omicron. "America is the first country in the world that has authorized a bivalent vaccine, where the bivalent vaccine targets the viruses out there,"

White House COVID-19 response coordinator Dr. Ashish Jha told CNN. While both brands of bivalent vaccine boosters have been approved, there are distinct differences between the

two. Moderna's new booster has been authorized as a single 50-microgram dose shot for those at least 18 years of age. Pfizer's updated booster has been approved as a single

30-microgram dose shot authorized for those at least 12 years of age. Additionally, to be considered eligible for either booster, individuals must already have received their

primary series of COVID-19 vaccinations and at least two months need to have passed since their last shot.
