I could see adding a covid shot every year if they are able to tweak it the way they do the flu shot. The covid vax worked great against the original, not so good against Delta and probably worse against new variants.
for 2 weeks solid and then another week of working about half time. I don't ever want to be that sick again if I can help it. I don't work, I don't get paid. So far so good. Covid knocked me out a few days and slow for a few more which seems better than it could have been if I wasn't vaxxed, but I don't know for sure.
