Even if the vaccines aren't super effective against variants, still seems worth it to get them. I get the flu shot every year. Some years it provides more protection than others. Some years the protection is negligible. Either way, the added protection is a freebie, even if the annual vaccine doesn't match up well against the dominant strain that year.
They're also working on oral antiviral pills to combat COVID infection. Even if you're resigned to catching it eventually, the longer you hold off, the better and more readily available the treatments will be.
