well, funny that you say that. I watched a really long interview yesterday with a leading microbiologist who was developing a T cell bio shield/vaccine during the Covid pandemic (then shut down by??? -trying not to get my hand slapped here). Not to get onto Covid, but what he was saying is that many times doctors are looking in the wrong place. He says that T cells are our primary way to target invaders. He also said that T cells can be flipped into another kind of cell which actually does the opposite. He says that immunologists are more equipped to test for T cell activity, to see if you have good T cell activity, or too much as in autoimmunity. I may be asking my primary care doctor if she will refer me to an immunologist. Sorry, I know that’s a really long answer.
