It has been claimed that the Covid-19 vaccines Pfizer-BioNTech and Moderna could provide protection for much longer than anticipated.
According to the information obtained by the New York Times (NYT), a group of scientists has obtained evidence that the Pfizer-BioNTech and Moderna vaccines create a strong immune reaction in the human body that can protect against Covid-19 for years.
EFFECTIVE AGAINST THREE VARIANTS
The new study also showed that these two mRNA vaccines produce highly neutralizing antibodies that are effective against three variants of Covid-19, including the “beta variant” that is said to reduce vaccine effectiveness.
Leading the research, St. “This is a good sign that our immunity is more resistant than the vaccine,” said Ali Ellebedy, professor at the University of Washington in St.
The study, which was also published in the journal Nature, found that about four months after the first dose of both vaccines, the body’s lymph nodes still have germinal centers that effectively train immune cells to protect against future infections.
Scientists’ research does not make any determinations about the effectiveness of vaccines against the “delta variant” of the corona virus, which is more contagious than other variants.
