I'm hoping they'll incorporate covid into the flu vaccines. It seems to be becoming a strain of flu. I know some don't take flu vaccines, but I have no problem with that. Yes, covid has mutated, and seems like taking another booster is once again closing the barn door when the horses have already got loose, and I don't feel I'll need another Covid booster. But it's a work-in-progress. I still believe that a combination of factors staunched the spread, early on, when it was more virulent, such as social-distancing, isolating, and masking. I know it will never be provable to the satisfaction of everyone that a vaccine helped, but I believe it did. IF the vaccine lessened symptoms, it was useful, when the virus was still strong. There was a time, at least here in the US, when cases of that led to hospitalization were mostly amongst the unvaccinated. Sure, they hoped that the vaccine would stop the spread, but it didn't seem to do that. But it DID seem to lessen symptoms. You can believe that your case was mild because the stain is milder, or because you're vaccinated, or some combination. Question: do you regret taking the vaccine?
