Is it really scientific (?) to compare the first 6 months to the second? That is, for example, Covid ravaged extended care facilities. Was that the virus of too many facilities being ill prepared?

As for recently, "unvaccinated" is fairly broad and in aggregate hides important details. That is, are those ppl unjabbed by choice, or by necessity (i.e., immune compromised, pregnant, nursing homes, etc.) Why isn't this important distinction made?
