Not sure what you mean, if the test determines I have immunity similar to what a vaccine provides and knowing that I choose not to get it, what are the downstream impacts?
I see, I guess I don't know either way, seems like something that isn't particularly difficult to study though so I'd be surprised if it wasn't known at this point.
I'm sure it's quite difficult to study, but no less so than studying the vaccine. I'd be surprised if we didn't already know at least as much about natural immunity, but whether the media are effectively communicating that information is another question.
