COVID bivalent boosters

As you may recall, spouse B, daughter T, and I were all participants in the Phase III clinical trial for the COVID-19 vaccine from Pfizer/BioNTech. We then all participated in a follow-on third dose trial. B and I left the trial this spring because we were eligible to receive a fourth dose and wanted the extra protection before travelling. T stayed in the trial until its end earlier this summer.

Here in the United States, a new booster was recently approved which combines the original formulation with a new one designed to better combat the Omicron BA.4 and BA.5 variants. BA.5 is the dominant variant currently in the US, accounting for about 88% of cases. About 11% are caused by BA.4. The new booster is expected to strengthen protection against serious illness/death and, one hopes, cut down on symptomatic infection somewhat, as well.

Given that I am still trying to remain COVID-free and that I have several trips coming this fall, I decided to receive one of the new boosters at my local pharmacy. I chose to receive the Pfizer formulation because all my others have been theirs, although there is a Moderna version which is also a fine choice. This was my first time receiving the vaccine in a pharmacy setting. My prior doses had all been in a medical office or a state vaccination site. I made an appointment online and everything was very fast and efficient.

Dr. Ashish Jha, who is the White House COVID-19 response coordinator, and Dr. Anthony Fauci, the long-time director of the National Institute of Allergy and Infectious Diseases, have said that it is possible that we may have reached a point where an annual booster will be enough to protect the vast majority of Americans from serious illness/death from COVID, similar to annual flu shots. Some people who are especially vulnerable due to age or medical condition might need more frequent boosters. The wild card, though, would be the emergence of a new strain that could evade our antibodies and current vaccines.

So, my message is to receive one of these new boosters as soon as they become available wherever you are. The US has been first to authorize them, but it seems they will become more widely available globally soon. Remember, though, that these are booster doses given to people who have already completed an initial vaccine series. If you haven’t completed an initial vaccine series, start NOW!

Meanwhile, here in Broome County, our community risk level is still medium. While I wait for the new booster to take full effect, I will still mask for indoor gatherings and shopping. I’ll be evaluating what to do after that, although these boosters are so new that data may be hard to come by.

I hope to stay well and hope that you do, too.
