The antibodies that the body produces in response to a new coronavirus infection or vaccination may last, after all, for longer than just a few months. This is the conclusion of a study conducted by a group of scientists at the University of Washington School of Medicine in the United States of America and the University of Bergen in Norway, published At the end of May in the prestigious Science magazine.
For the first time since the outbreak of the pandemic, researchers have found long-lived Covid-19 plasma cells capable of producing antibodies in the event of a new infection in people who have recovered from Covid-19, suggesting broader — and even lifelong — protection than indicated. Other studies.
One such study, conducted in Portugal, concluded that antibodies against the coronavirus remain in the body for up to five months after infection, which is a “relatively short” period for the immune response, considered the coordinator of the work, Marc Veldoin, of the João Molecular Medicine Institute. Lobo Antunes from the University of Lisbon. However, Vedwin was optimistic about the results, because the antibodies “can, and are likely to, spread to most people during that time.” He said To Lusa Agency.
According to work recently published in Science, after a patient is given a treatment, the antibody level drops abruptly over the next four months. However, after 11 months, researchers are still able to find defenses against the virus.
This is a very important note. He said Immunologist Rafi Ahmed, of Emory University in Atlanta, whose team discovered the cells identified by this new work in the 1990s, but the expert urged caution, reminding the scientific journal that it is still too early to realize the long-term consequences. “We’re not looking at five or ten years after the injury,” he said.
