The two mRNA vaccines from Pfizer and Moderna are monovalent, targeted to the KP.2 strain of the Omicron variant of SARS-CoV-2. As you can see here, KP.2 now accounts for a very small percentage of infections, with KP.3.1.1 now dominant. But this doesn't mean the current vaccine won't be effective at all, since that depends on how much the virus has mutated and what the mutations do to virulence and transmission. So the vaccine is still strongly recommended to lessen the chance of severe illness and possibly Long COVID.


We're going to be chasing our collective tails and remaining behind the curve until intranasal and/or pan-coronavirus vaccines are approved in the United States. (Some have been released elsewhere.) So far, the only politician I've heard calling for high-level funding has been Bernie Sanders.


By the way, some authorities continue to advise not to take analgesic medication before vaccination, as that may blunt the immune response. At one point, NSAIDS such as Naproxen were especially frowned upon, but I've read several studies that counter the claim.


Number of states in our country minus the number of Supreme Court Justices?
