Yes. It does make sense. The only reason it should concern immunocompromised patients is that we are all want to know -- beyond the "yes" I have antibodies from exposure or the vax -- is WHAT LEVEL DO I HAVE? The research studies from Paris and Toronto, I've posted on here earlier, mentioned specific percentages. For example, 40% or 55% or less than 11%. So I'm just curious scientifically as to how they can be so specific and other people are saying the tests don't exist. It's confusing as with everything in this Covid19 era. But you've made given a reasonable explanation.
