This preprint is yet another study showing that infection+vaccination gives a stronger and more durable response that vaccination alone or infection alone. There have been so many studies showing that result that I am getting tired and bored with them, and probably will not post any more.
This preprint about vaccines and pregnancy found:
- Pregnant or lactating women had lower COVID-19 antibody levels than other women after one dose, but their levels popped up to comparable with a second dose.
- Mothers carrying boy fetuses had lower COVID-19 antibody levels than mothers with girl fetuses.
- COVID-19 antibody levels were lower in boys’ cord blood than girls’ cord blood.
From this tweet:
This article talks about the contractual language Pfizer uses which can hurt equitable vaccine distribution.
