Once infected with the corona virus, the immunity that the body develops lasts at least five months. A team of researchers from the University of Arizona made this claim.
The team of scientists examined 6 thousand corona-infected. "We've found that even after five to seven months, the body still has corona antibodies," said they, an associate professor at the University of Arizona. We started the investigation as soon as we got the answer to this question. The report, published in the journal Immunity on Wednesday, states that there is at least five months of immunity.
Scientists have also explained the matter. When the virus first infects, the body's immune system is responsible for making antibodies to the transient plasma to start the fight against the virus quickly. The presence of this antibody in the blood is found 14 days after the infection. In the second stage, chronic plasma cells produce high-quality antibodies. It creates long-term immunity. They have been experimenting with this for several months. They believe that antibodies stay in the body for five to seven months. Even after that there is immunity for several more days. Earlier, however, several studies have claimed that the body of the victim is developing temporary immunity. After that the level of antibody is decreasing very fast. According to this concept, those studies targeted transient plasma cells. Chronic plasma cells were not observed.
