The OP's subject was pertaining to the availability of the vaccinations. Whether or not the shots work is not what the OP was asking.
That said, everyone is different regarding these Covid and Flu shots. I will not discourage or encourage anyone regarding the shots. Most of my younger family, under 50 have had Covid at least once, before and after the shots were available. None of them have had the shots and none of them were hospitalized or died. Of the family members that have had the Covid shots, all of them have since had the virus at least once; most of them at least twice. Personally, I have received only the first two shots, ONLY because I thought they might help prevent me from infecting my wife if I caught it doing all the shopping, etc. IMO I was probably wrong in that assumption. I have not had a flu shot in over 50 years and have never had the Flu. My choice and it has been working for me so far. My wife and I have had Covid once and those in our family that have gone on to have the boosters have had Covid at least twice. Just saying, not suggesting anything. Personally, I have no intention of getting any of the boosters. What others do is their choice. My doctor asked me if I wanted a flu shot(as he always does) and I declined. He did not try to persuade me. I asked him if he had his shot and he said that it was required by his employer (VA). He NEVER/NEVER suggested that I get the Covid shots. I wonder why. I am curious as to how many VERY healthy people, such as young and healthy athletes have suddenly died due to stroke or heath attacks and then we hear that they had been vaccinated for the Covid. Just saying. I also know of a gentleman and his wife in the Villages that had a bad case of Covid before the vaccinations were available, and they are still doing very well. Not sure if I subscribe to the "sky is falling" group. Like I said before, I have no wish to dissuade or encourage anyone to get the vaccinations.
I hope the OP finds what they are searching for.
