KATHMANDU: A new research published in the CELL journal on Friday showed that large segments of the population may be immune to COVID-19, and do not need either antibodies or exposure in order to develop immunity.
According to the research, which was quoted by journalist Nadav Eyal and written by well-known researchers, some people have cellular immunity to COVID-19, possibly as a result of exposure to other, milder, strains of coronavirus, which cause only cold-like symptoms.
Such people would have cells that can recognize coronavirus and eliminate it before they become infected with the disease and develop COVID-19-specific antibodies.
The research, the first of its kind, is based on initial findings but opens up many possibilities regarding the development of a vaccine, as well as the possibility that some people will not be affected by COVID-19 due to prior immunity.
