Are there any people left that haven't had their first exposure? The argument makes more sense when you take into account that the interesting case is actually "given that you've already had covid, should you get vaccinated?" rather than "given no exposures yet, should I make out with someone that has it or should I get vaccinated". I've seen a lot of noise about the latter case, and a lot of overlooking the former.
