People not infected again in 6 months after recovery

People not infected again in 6 months after recovery

People not infected again in 6 months after recovery. Researchers from the University of Oxford in the United Kingdom published a study showing that patients who have been diagnosed with COVID-19 pneumonia will most likely not be infected with the virus again within 6 months after recovery.

This research data is taken from the regular quarantine data conducted by more than 12,000 medical staff in Oxford University Hospital. It was found that among the 1,246 medical staff with antibodies, no one had new symptoms of infection.

At present, the researchers have not been able to obtain enough information to know the situation after 6 months, and will continue to collect data to further know how long the immune protection can be maintained.

Alin, a professor at the University of Oxford, is one of the researchers. She said that the relevant results are “good news” and can be sure that most people will not be infected with COVID-19 pneumonia in a short period of time.

This week, the La Jolla Institute for Immunology conducted a similar study.

In this study, they followed up and surveyed 185 adult patients who have recovered from the new coronavirus, aged 19 to 81, and most of the respondents were mild patients.

 

Researchers have found that most people have an immune memory of the new coronavirus for 6 months or more, and the reduction of immune cells in the short term is relatively slow.

In other words, within 6 to 8 months after being infected with the virus, most recovered patients still have enough immune cells to prevent secondary infection with the new coronavirus.

 

Another paper published in the Medical Journal of Immunity last month also published a similar view. The paper pointed out that mild patients can produce enough antibodies to resist the new coronavirus for at least 5 to 7 months after infection.

Other studies have also shown the durability of immunity, and experts have expressed that this is an encouraging signal and a good sign for vaccine development.
