the vaccines work and protect against the virus but in my opinion they have not been tested enough you cannot compress a test of years in a few months so the adverse reactions have not been studied enough, especially those in the long term, i will not vaccinate, i hope they do not introduce the mandatory vaccine
Not all of them worked. In EU, AstraZeneca vaccination has been stopped because of a safety issue. But I don't know if it's okay again and safe to use.
The testing was done quickly and expedite for most of the vaccines. There's not enough time for them to test for years and that's why most of the vaccination today are likely still in trial.
