Is it better to get the current booster now or to wait until the fall for boosters that cover the BA.4 and BA.5 variants?

— highly contagious. In fact, I came down with COVID-19 the same day as Tony Fauci. I've had a second booster.

There was quite a bit of data presented, but just some highlights that struck me were projections that there may be a novel variant emerging this fall where we might even have less protection from our existing vaccine such that the estimated deaths, if you look at a 1-year time frame from March 2022 to March 2023, could vary between 95,000 and 211,000. This is far more than might be seen withWe do know that the current vaccine, although it neutralizes BA.4 and BA.

The VRBPAC voted 9 to 2 in favor of an Omicron component for the vaccine. There were two negative votes that mainly brought up that no one would know whether Omicron or any of its subvariants would be circulating in the BA.4 or BA.5 category, or any of the Omicron variants, later this year. What should we say about whether a patient should get a booster now or later? I would say that, to be up-to-date, which is the CDC parlance, getting all recommended boosters is the best strategy. That is now the bird at hand. We do know that a second booster was helpful in reducing serious illness in people over 60 years of age, and other data from Europe suggest the same.
