According to the research, Humans may never develop immunity against COVID-19, according to new research on antibodies by Chinese and American scientists.
Their conclusion was based on a study looking at whether hospital workers in Wuhan who were directly exposed to infected patients at the early stage of the outbreak had developed antibodies. The deadly new disease was first detected in the Chinese city late last year.
At least a quarter of the more than 23,000 samples tested could have been infected with the virus at some stage, according to the scientists. But only 4 per cent had developed antibodies as of April.
