I thought all antibody levels reduce overtime, but when there’s a “memory” that will let them regenerate when needed. Is bloodstream antibodies really an important indicator to anything??


But… this is what to be expected. The immune system does not need to produce antibodies endlessly, it just needs to remember doing so.


Begging ppl to understand that antibody levels does not equal vaccine effectiveness


Amazingly like the expected immune response you all learned about in a&p
