iirc for some reason the amount of antibodies you have falls sharply after 1-3 months and you're vulnerable again. anecdotally, a friend of a friend (EMT) had covid like 4 times before vaccines were available.
- furgooswft13 5y agoCan someone explain why this would not be the case for vaccines? If antibodies fall off quickly from an actual infection, why would this not also happen for the antibodies produced because of taking the vaccine?
- strogonoff 5y agoAntibody count falls at first, but relevant antibody-producing cells were found[0] to remain in the bone marrow. I suppose it is not the only determining factor in susceptibility to symptomatic infection, though. I’d be curious if currently available vaccines stimulate such preexisting antibody-producing bone marrow cells of past COVID patients (which sounds more optimal on the face of it), or they trigger yet another variety of antibodies to be produced in addition to the “native” one.

- mfkdkslsn 5y agoBullshit. SARS 1 produces immunity against COVID and every other coronavirus has natural immunity. Your friend had some colds, the flu, maybe COVID once, and potentially false positive tests. Antibodies do drop but they're not the only part of the immune system. T cells have memory and will remember the antigen
