"but mavica just mute the word vaccine on twitter!" NOBODY uses the word vaccine on those kinds of posts. they either use "shot", which is way too broad a word to mute, or "super soldier serum" because they think they're cutesy, or on image captions, which are impossible to mute.
also if your proposed solution is "close the borders!" instead of, or without additional solutions to actually HELP US, i'm blocking you on the spot. go sit on a fucking pole
