MUMBAI: Covid-16 antibodies may not last for more than two months, according to a study conducted on infected health care workers at the ‘JJ Group of Hospitals’. “We studied 401 healthcare workers at JJ, GT and St. George’s Hospital,” said Dr. Nishant Kumar, the study’s lead author. Among them were 24 people who had Covida-positive in the “RTT-PCR” seven weeks before the end of April and early May.

The June survey found that none of the 24 had antibodies. There were 37 health workers in the ‘JJ Hospital4 Sero Survey’, which received a positive PCR three weeks ago and five weeks ago, respectively. Of those, 80% of the three-week group 4 had antibodies in the body, while less than half of the six-week-olds had antibodies in less than half (37.5%), Dr. Kumar said. The issue of antibodies has recently been discussed. It is the antibody that protects the infected person from being infected repeatedly and the person who has been vaccinated against the virus. A few previous studies around the world have also shown that antibodies are at the top in three weeks. After that, the antibodies are destroyed. Therefore, the research team said, people should be given multiple vaccine doses rather than a single dose.
