everybody's heard the expression what gets measured gets managed what we can measure we tend to fixate on and unfortunately when it comes to measuring immune strength we really have one tool in the toolkit which is to measure circulating antibodies which are not the same as neutralizing antibodies which are part of the you know b cell immunity and then you have this other thing that you've alluded to marty called t cell immunity i don't think we need to go into it in great detail i did a podcast with steve rosenberg that was cancer focused but we had a totally in-depth discussion on b-cell versus t-cell immunity so we'll we'll we'll send people there if they want the primer on it but the upshot is we don't have a laboratory test to measure t-cell immunity we don't even have a commonly available test to measure neutralizing antibodies we just measure circulating antibodies so we can't really even measure what memory b cells are doing do you think that's a little part of the problem here in that we're kind of flying blind and making a lot of assertions about immunity based on arguably the least important thing that you could measure
