Iron man I hope your feeling better, I totally get your point and where you are coming from, and its completely sound thinking.
There is no need to go out and increase your exposure or introduce your body to something that could cause excessive harm.
From this view point the great thing about the vaccine for covid vs another medication, treatment, or exposure is two things.
- There is a high probability that someone who doesn't take the vaccine will get Covid as evidence by the rapid spread. Most of us no matter how hard we try are going to get it eventually without a significate intervention or vaccine.
- The vaccine payload is the outside proteins of Covid. So by either taking the vaccine or contracting Covid you are going to get exposed to these proteins. The vaccine works by preparing your body for the virus like a practice run. Its not adding anything different to the body.
Now your other option for specials cases is antibody therapy. It hasn't been done much due to the complications of blood type, donors and logistics is to get the antibodies from anther person. So for people who cant instruct their body to make the defense with a vaccine they can get some temporary immunity with antibody therapy.
