Believe it or not, SGilbert, there are elements where I agree with you!
Most vaccines do work very well. Like Cheryl says, remember the coronavirus vaccines were rolled out very quickly and I think they have worked remarkably well! (See earlier data and more if you want it...) We're in a
very different situation now compared to 2020, as a result.
The current vaccines don't totally prevent infection, no, but they hugely reduce your chances of a very bad outcome if infected, and that is good enough for me. If they reduce viral loads of infected people, they may reduce the speed of the spread too (but don't stop it, no).
Boosters: yup, we need boosters. It evolves quickly. "Coronavirus" is an umbrella term for a type of virus structure, and another type of coronavirus is the common cold, which is notoriously difficult to find a cure for (not least because of mutations)! When travelling for work, I've had to have vaccinations for other things... and, yes, boosters. And I read through the vaccination card to see how long each vaccination lasts; most certainly are not for life, put it that way. So this virus is not the only one needing regular boosters.
Finally, yes, there are potential side effects. Thankfully, they are rare, but they can happen. The same for any medication or vaccine,
this is not unique. Let's go back to data; to cold, hard facts and not scare stories. As you've brought up side effects and I remember the one that caused panic was the possibility of blood clots, please can you tell us the risk of blood clots due to:
1) AstraZeneca vaccine
2) Pfizer vaccine
3) Birth control pills
4) Smoking
5) Actual infection by the coronavirus ("COVID")
It's a useful comparison. It nails down some facts and the relative risks of each... I hope you'll look these up and come back to us.
