It also kept track of an extra 31 members of staff who volunteered to have routine antibody tests.Researchers found that levels of antibodies that can combat the coronavirus peaked three weeks after the start of signs but then decreased. The researchers noted that their study found the antibody action to Covid-19 was similar to that of other human coronaviruses, such as SARS (extreme acute breathing syndrome) and seasonal coronaviruses associated with common colds, in which an individuals antibody reaction tends to “wane over time, from as little as 12 weeks to 12-34 months after infection. Saying on the research, she stated it highlights that antibody reactions to SARS-CoV-2 (or “serious acute breathing syndrome coronavirus 2”– the infection that causes the Covid-19 disease) circulating in the blood are declining after infection and that further research study is required to figure out the level of antibodies needed for protection from infection.
