I know several people in Europe who got Covid several times despite several vaccinations.

I don't.

Anecdotal evidence can be dismissed with anecdotal evidence.

If that's your burden of proof then you'll never find someone good enough

I mean thats science?

Individual experiences dont give any indication of population level outcomes - there is too much variability.

Some people see their cancers spontaneously go into remission but you wouldnt make a claim that cancers usually go into remission by themselves.

No, that's not science. That's you weaponizing science in your crusade against things you don't like. You don't like vaccines, so you make bullshit claims that are unsubstantiated but hard to disprove, and then eventually people get tired of arguing with you and you have your way.

Yes it is science. No scientist will look an individual anecdote and make any sort of claim from it. That's high school science and statistics.

Your personal attack is again HN rules. And I'm not sure where you're coming from - I've been vaccinated.

This "vaccines can do no wrong" bandwagon is as damaging to science as the "vaccines are all bad" group.
