Scientists in Shanghai say some recovered patients show no signs of the neutralising antibodies

[South China News] - Researchers in Shanghai hope to determine whether some recovered coronavirus patients have a higher risk of reinfection after finding surprisingly low levels of Covid-19 antibodies in a number of people discharged from hospital.

A team from Fudan University analysed blood samples from 175 patients discharged from the Shanghai Public Health Clinical Centre and found that nearly a third had unexpectedly low levels of antibodies.

In some cases, antibodies could not be detected at all.

...All of the patients had recently recovered from mild symptoms of the disease and most of those with low antibody levels were young. The researchers excluded patients who had been admitted to intensive care units because many of them already had antibodies from donated blood plasma.

...The team also found that antibody levels rose with age, with people in the 60-85 age group displaying more than three times the amount of antibodies as people in the 15-39 age group.

...Huang said 10 of the patients in the study had an antibody presence so low it could not even be detected in the laboratory.

These patients experienced typical Covid-19 symptoms including fever, chill and a cough, but might have beaten back the virus with other parts of the immune system such as T-cells or cytokines.

#4  Considering the diverse and important role helper T cells play in the immune system, it is not surprising that these cells often influence the immune response against disease. They also appear to make occasional mistakes, or generate responses that would be politely considered non-beneficial. In the worst-case scenario, the helper T cell response could lead to a disaster and the fatality of the host. Fortunately this is a very rare occurrence.

Not so rare now I guess.
