Melbourne: Immunity against this infection in people who recover after Coronavirus infection (COVID-19) is at least eight months after infection-free. This claim has been made in a new study. This study reinforces the expectation that the anti-Covid-19 vaccine will be effective for a long time.
Earlier in many studies, it was claimed that antibodies against the coronavirus cease to exist only a few months after the infection (Coronavirus Antibodies), after which concern was raised that people might soon be immune against It may, but new research published in the journal Science Immunology has dispelled these concerns. Experts, including scientists from Australia’s ‘Monash University’, say that special ‘memory B’ cells in the disease-resistant system “remember” the infection of the virus and that if a person comes in contact with the virus a second time, protective antibodies The rapid resistance of the disease causes the immune resistance to function. For this study, the researchers selected a team of 25 patients of Covid-19 and took 36 blood samples from the fourth day to 242 days after infection. Scientists found that antibodies against the virus began to decrease 20 days after infection.
However, he stated that all patients had ‘memory B cells’, which recognize one component of the virus’s two components ‘spike protein’ and ‘nucleocapsid protein’. ‘Spike protein’ helps the virus to enter cells. Scientists after analysis found that memory B cells remain in the body until eight months after infection. They believe that this result reinforces the expectation that the effect of the anti-virus vaccine will last longer. “These results are important because they show that patients infected with Covid-19 have a disease-resistant capacity against the disease,” said Meno Val Gelm of the Department of Immunology and Pathology at Monash University.
