A new study conducted by Chinese and American scientists said that humans may never develop immunity against the coronavirus, the South China Morning Post reported.
The conclusion was based on a non-peer reviewed study looking at whether hospital workers in Wuhan, where the infection was first reported, developed antibodies, after being exposed to the disease.
The report said only 4 percent of the samples studied had developed antibodies as of April. This was based on the assumption that at least a quarter of the more than 23,000 samples tested were infected.
