Its all about odds. Which one are you more afraid of? If i was 21, definitely the vaccine. At my age (way past 21), Covid is more dangerous. I got the vax. Didn’t even get a sore arm.
I might get coivd, then I might die...
If I vax I will get the vax and it’s possible side effects.
BTW I already had covid..
so it’s kinda a moot point with me now ;)
