Patients who have had a mild or asymptomatic coronavirus can retain long-term immunity to the disease.
This is the conclusion reached by British scientists. The results of their research are published in the journal Science Immunology. It is noted that experts have studied the data of 136 health workers in London hospitals. 76 of them will suffer asymptomatic or mild coronavirus. The researchers looked at responses to antibodies and T cells.
As it turned out, even 16-18 weeks after COVID-19, 89% of healthcare workers still had neutralizing antibodies.
As noted by study author and professor of viral pathology at Queen Mary University Blizzard Institute in London, Dr Corinna Padé, this is evidence of persistent antibodies and T-cell immunity to SARS-CoV-2, “that many have been waiting for”.
At the same time, the researchers emphasized that at this stage it is not known how long immunity can last, because the participants were tested only a few months after infection.
“A remarkable number, about 90 percent of people, have the combined potency of strong antibodies that prevent the virus from entering, combined with T-cell responses to various parts of the virus that prevent it from surviving.”, Pade explained.
As OBOZREVATEL wrote, a study conducted at the University of Monash (Australia) showed that immunity to the coronavirus can persist for up to 8 months.
