One's model of "statement made by the POTUS" should be more like 'statement made by mildly likeable (to some segment of the population) boomer dad who probably doesn't know what he is talking about.' It'd be a different thing if a public health official said something like this (and I don't know if they did, but I certainly wasn't left with the impression that it was impossible for me to get vaccinated and still get covid).
