A new study on vector and RNA vaccines, which are more effective against hospitalization

U.S. researchers have found why Pfizer and Modern vaccines are more effective at preventing hospitalizations and deaths than infection – antibodies are declining, but other defenses remain in place. “Labor”

Laboratory experiments with blood samples from 61 fully vaccinated showed that after six months, the antibodies that immediately neutralize the virus decreased. However, so-called B cells, which produce new antibodies when they encounter the virus, increase in size and recognize variants more successfully.

“The immune system has support,” said study leader John Wery of the University of Pennsylvania.

The study was submitted for publication on the BioRxiv portal before review.
