not a ruling, lol. nor do i try to pass myself off as an expert on anything. merely a CRITICAL thinker with a decent education and a damn fine BS detector. all available science here(which i trust a hell of a lot more than Russias) says "herd immunity" is not happening because the antibodies disappear after a few weeks in studies so far. i doubt the Russians antibodies are any longer lasting than ours. both here and in China (China admitted it, GASP!) there have been individuals being infected more than once. how many times do you have to catch it before you are "immune", and why does that not work with the common flu? yeah, it WAS easy, lol.
sorry man, but i think you missunderstood what the scientist is saying in that article. he agrees that the antibodies disapear, simply put he is saying our bodies recreate the needed antibodies when we need them next time. ie the antibodies go away once you are healthy again, but your body now knows how to create those again if needed.
now please don't misuunderstand, i don't know if thats true. but i do find it facinating as an idea and it's some how quite logical too.
