How does this compare with the rate of antibody persistence for people who have antibodies acquired through infection? Last I remember reading, initial antibody response via vaccines was supposed be ~10x more. Is it the case that infection-borne antibodies are fewer in number but more persistent?
Another aspect I'm unclear on--with mRNA vaccines your body is essentially getting blueprints for producing antibodies, and it does that by itself. What mechanism controls the amount of antibodies being produces, and can that be adjusted/regulated? I'm assuming there's a relationship with vaccine dosage, but not clear on the mechanism.
The logistics of biannual boosters seem like they'd be staggering.
