Sweden's state virologist said yesterday that herd immunity in the country has been surprisingly slow to develop.
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.
"People are unlikely to produce long-lasting protective antibodies against this virus," the researchers concluded.

I wonder if this lack of antibody production is another feature of this weaponized virus. Those crazy Chinese sure think of everything!
