India's Covid tally has reached 80 lakhs and globally there have been 43,766,712 confirmed cases. People are no longer afraid of this pandemic rather with an attitude of letting the ailment come and go. This attitude sounds to be a solace, but it is not.
According to a study by scientists at Imperial College London antibodies against the novel coronavirus is declining rapidly. They tracked antibody levels in the British population following the first wave of COVID-19 infections in March and April.
Their study found that antibody prevalence fell by a quarter, from 6 per cent of the population around the end of June to just 4.4% in September.
"We can see the antibodies and we can see them declining and we know that antibodies on their own are quite protective, On the balance of evidence I would say, with what we know for other coronaviruses, it would look as if immunity declines away at the same rate as antibodies decline away, and that this shows waning immunity at the population level", Wendy Barclay, Head of Department of Infectious Disease at Imperial College London told reporters.
People who confirmed their Corona with the gold standard PCR test had a less pronounced decline in antibodies than those who were asymptotic. There was not much change in the level of the antibodies of the health workers, probably due to the repeated exposure to the virus.
The study of the Imperial College has not yet been peer-reviewed, and it remains as a pre-print paper. Barclay also added that "A good vaccine maybe better than natural immunity".
The study might turn out to be profound; when talking with the infected people, most of the people are saying, they feel dizzy and tired most of the time as if there is a huge change that had happened in their body after the infection of COVID-19. People also suggest not to be very careless and should boost the immunity to fight the virus out of the body and society.
