Bivalent Booster Shot

My work is once again offering vaccine shots. This time, the shot given are bivalent boosters, and we can choose which company’s product we want. I contacted my nephrologist to see if I should get the booster, and the answer was a definite “yes, but wait.”

Similar to the reason given when I was rejected for Evusheld shots, I should have enough immunity from my COVID infection, and any antigens produced will be neutralized by my immune system. The recommendation is to wait 4-6 months before getting the booster post COVID infection.

I have a lab draw Friday morning, so I was going to drive in to work afterwards for the booster shot. Now I think I will wait a few more months instead.

Today, the U.S. Food and Drug Administration amended the emergency use authorizations (EUAs) of the Moderna COVID-19 Vaccine and the Pfizer-BioNTech COVID-19 Vaccine to authorize bivalent formulations of the vaccines for use as a single booster dose at least two months following primary or booster vaccination. The bivalent vaccines, which we will also refer to as “updated boosters,” contain two messenger RNA (mRNA) components of SARS-CoV-2 virus, one of the original strain of SARS-CoV-2 and the other one in common between the BA.4 and BA.5 lineages of the omicron variant of SARS-CoV-2. 

The Moderna COVID-19 Vaccine, Bivalent, is authorized for use as a single booster dose in individuals 18 years of age and older. The Pfizer-BioNTech COVID-19 Vaccine, Bivalent, is authorized for use as a single booster dose in individuals 12 years of age and older. 

The monovalent COVID-19 vaccines that are authorized or approved by the FDA and have been administered to millions of people in the United States since December 2020 contain a component from the original strain of SARS-CoV-2.
