As the “New York Times” wrote, in the course of the study, scientists analyzed 41 vaccinated participants in terms of the level of activity of the so-called reproductive centers of B cells, which are responsible for the production and development of antibodies to viruses.
Although these usually disappear as early as one month after vaccination, they remained highly active for all study participants 15 weeks after receiving the first dose of the vaccine. This indicates not only long-term immunity, but also – due to the development of the cell – resistance to various mutations of the virus.
A study by scholars from St. Lewis was the first of his kind, but another was proposing the long-term immunity that vaccines provide. This, in turn, means that additional doses of vaccines may not be necessary – especially for people who have contracted Covid and are vaccinated. However, the potential danger is the development of the virus, which may allow it to “bypass” the antibodies in the future.
“Anything that requires a booster dose will depend on a new, non-faded immunity,” Deepta Bhattacharya, an immunologist at the University of Arizona, told the New York Times.
According to team leader Ali Ellipida, in people who have not been infected with the coronavirus but have been vaccinated, the booster dose may have the same or better effect than the previous infection, providing long-term immunity to other variants of the virus as well.
Ellipedi added that although people who were vaccinated with a single dose of Johnson & Johnson were not involved in the study, he suspects that the vaccine does not elicit a strong immune system response like the messenger RNA preparations.
