Quaid-19 immunity lasts for at least 8 months, vaccination life expectancy: study

Melbourne: People who recover from a novel coronavirus infection have immune memory for at least eight months to protect against the infection, according to a new study that provides strong evidence that The Quaid-19 vaccine will work for a long time.
While previous research has shown that antibodies against coronavirus weaken after the first few months of infection, raising the risk that people may lose immunity quickly, published in the journal Science Immunology New research has eased these concerns.
According to scientists, people at the University of Monash in Australia, specific cells within the immune system are called memory B cells, which “remember” the infection caused by the virus, and if re-detected by the virus, its rapid Speed ​​stimulates the immune response through production. Protective antibodies
In the study, researchers recruited 19 patients with 25 covids and took 36 blood samples from them, ranging from day 4 post-infection to 242 post-infection.
Scientists found that antibodies against the virus began to release contractions only 20 days after infection.
However, he said that all patients have memory B cells that recognize one of the two parts of the virus. Spike proteins that help the virus enter host cells, and nucleoxide proteins.
Based on their analysis, the researchers reported that these virus-related memory B cells were permanently present for up to eight months after infection.
Scientists believe that these results give hope to the effectiveness of any vaccine against the virus, and also explain why there is very little real rehabilitation among millions of people who have tested positive for the virus worldwide. There are examples.
Menu Van Zelm, co-author of the study in the Department of Immunology at Monash University, said: “These findings are important because they show that, of course, patients infected with the Covid 19 virus maintain immunity against the virus and the disease. ” Pathology
“This has been a black cloud for potential protection that can be provided by any Code 19 vaccine, and it gives real hope that, once a vaccine or vaccine is ready, it will last a long time,” said Van Zelm. Will provide temporary protection. ”
