I just don't know where you get your info, but it's not correct. I cannot (well, will not) research and post rebuttals to your comment(s), but there have been people who have followed and reported on the terrible side effects of the COVID vaccine. I've taken the first 2 primary Pfizer shots and one booster. The gamble has so far had no serious effect on me, but I'm not taking any more, just as I do not take a flu shot.
(The side effect I'd be most concerned with in my case now is the reduction in the strength of my immune system)
