Antibodies from COVID-19 infection appear earlier, finds study

Antibodies from a COVID-19 infection begin to appear significantly only 14 days after a vaccine jab. But in people who have already been infected by the virus before, the increase can be observed in a week, a study has found. While underlining the importance of the follow-up second shot, scientists associated with the study suggest that, in mass vaccination campaigns, individuals who have been exposed to the virus could be prioritised lower than those who have remained unexposed.
According to several serology surveys, anywhere from 21%-60% of India may have already been exposed to the virus since March. While India currently does not face supply constraints — there are more vaccines available than those registering for shots as of now — this could change as more groups become eligible for the vaccine. Currently, only healthcare, frontline workers, those above 60 years, and those above 45 years with co-morbidities, are eligible for vaccines.
