The problem is when people are afraid of the vaccine because they think may have bizarre side effects. Vaccines stimulate the immune system. If you're afraid they might make you hallucinate, grow a second head, OR CAUSE AUTISM, it's not just ignorant, but destructive.

The worst thing I believe that can happen is it won't be effective. Other things are soreness at the injection site, maybe more of your arm, flu-like symptoms (the immune system response), and... that's pretty much it.

So if you're afraid to get the shot, don't get the shot. Just keep wearing a mask and keep avoiding crowds, or being physically close to people you don't know well, an keep doing that until the virus isn't circulating very much. And don't try to frighten people who don't have an issue with the vaccine. At worst, it could kill people. (Nobody is probably paying attention, anyway. Strange people on a strange little music forum.)
