Meanwhile, vaccines not only don't stop you spreading COVID but they appear to make it worse as UK and Swedish data shows. Thus there could easily be an argument to force you to not take the vaccine, on the grounds that you don't personally need the protection and it makes the epidemic worse. Would you like that?
It doesn't apply. It makes the (false) claim that anti-vaxxers don't have body autonomy. They do. No one is holding them down and making them take a vaccine. You've given the choice: get the vaccine or don't. But if you don't there are some negative consequences.
This was already the case prior to Covid. For example: sending unvaccinated children to public school.
Stop engaging in mental gymnastics and admit what you are supporting: mass forced violation of people's bodily autonomy.
Twisted how. It's exactly the same argument, identical in every way, to the one used for years by abortion supporters. It was seen as noble and obvious correct back then by the same people who deem it to be beyond the pale now. It's obvious they have no internal consistency.
