I agree. So many of these studies just seem to test for one type of antibody in a test tube, leaving out other types of antibodies and the rest of the immune system response (which is not fully understood). I'd like to see more numbers tracking infections across populations through time. Israel has done this with some of their studies. We'd have a lot more data if we asked every positive case how many shots and/or prior infections they had, and when, and a bit about their masking/lockdown precautions. I don't know if any states or counties are doing this.
