Yes - the shots they were handing out last fall were bivalent shots - meaning they were designed for more than one variant of COVID. I got mine in September. I've had five COVID vaccinations & credit them for the mildness of my illness. I fully intend to keep on getting vaccinated. Subvariants of Omnicrom seem to be the current majority of cases. And Omnicrom was in last fall's vaccine. I can't advise you - this is a discussion for your PCP because Humans have complex medical histories. But for me - every fall - along with my flu shot - I'll be getting vaccinated.
