NEW: The vaccines made by Pfizer-BioNTech and Moderna set off a persistent immune reaction in the body that may protect against the coronavirus for years.

The findings suggest that most people immunized with the mRNA vaccines may not need boosters, so long as the virus and its variants do not evolve much beyond their current forms (which they probably will)
Still, this study takes what one expert called a "heroic" approach to show that 15 wks after the first dose of Pfizer, people have very active germinal centers, a sort of bootcamp where B cells become increasingly sophisticated. That's much longer than expected
What I found fascinating is also how much we are learning about immunology generally, thanks to Covid. This is the first study to look at germinal centers in immunized people.
The idea that it's not just the virus evolving, the B cells are evolving and becoming more powerful and diverse, too, is super cool. Study by @TheBcellArtist with comment from @VirusesImmunity @PepperMarion and @deeptabhattacha
