Scientists have found evidence that Pfizer-BioNTech and Moderna vaccines induce a strong immune reaction in the human body that can provide years of protection against Covid-19.
The results of the research were reached by the New York Times (NYT).
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.
It was stated that this includes the “beta variant”, which is said to reduce the effectiveness of the vaccine.
Leading the research, St. “This is a good sign that our immunity is more resistant than the vaccine,” said Ali Ellebedy, a professor at Washington University in St. Louis.
PROTECTS AFTER FOUR MONTHS
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.
