I definitely understand your perspective 100%
On the other hand, why not just get it – lehashvos hadvarim?
Does it hurt? What’s the harm?
I myself also got very sick with covid last year (I am 27 with no health issues, and I was preparing myself to accept death as real possibility. Hodu LaShem I eventually got better.)
I have the antibodies, so I most likely did not need the vaccine.
But I got the vaccines anyway! Because why not?! It makes others feel better, which is probably the most important reason to get vaccinated – it’s very important not to cause other Yidden anguish, especially your family members regardless if they are right or wrong. Don’t you want to help others so they shouldn’t be stressed out? Also, if there is even the remote possibility that the vaccines will protect me from getting sick – even if it’s just a cold, so that’s good too. It’s like extra credit. I’ll admit, I got very sick each time I got the vaccine because having antibodies could cause your body to react strongly to the vaccine. But it wasn’t a big deal, I got it over with. I’m done. So nu, why wouldn’t you just do it?
Full disclosure (I am definitely not interested in getting a booster because I already got very sick twice from from the first two.) But at least I can truthfully state I am fully vaccinated.
