So, if you have post-infection immunity against virus that you can prove (test blood reactivity against virus protein), and it's likely better than typical 2 doses (research shows), you should still be legally required to take 2 jabs even though there are often side effects, even serious ones?

Not OP, but if arguing against it is anti-vaxx, then I guess you should call me anti-vaxx and I'll call you unreasonable.
