@hansw I beleive that is the question i answered.. if you dont feel I answered your question please elaborate how and i will try to.
My simple answer is, no one should have any right to force any other person to take a drug in order to have access to society. The one exception where I could find this acceptable is if the group setting is of a topic or situation that specifically hosts immunocompromised individuals. Like if they required people to have a full set of vaccines in order to get into the acancer ward of a hospital, or to visit a friend with a weak immune system, then by all means I think it is reasonable in those sorts of private settings to have restrictions out of medical necessity.
however if we are talking general group settings, then...
I am opposed to any law or societal norm that requested any medical information about me of any kind or requires that i take some drug regardless of my personal opinion about it
The issue here is two fold
1) I have an absolute right to complete confidentiality of my medical history and decisions
2) I should not be forced to take a drug in order to gain full access to society in general. That violates the principle of bodily autonomy.
