The detection of colic immunity takes at least half a year, the study showed



The Oxford virology study promises tens of millions of people who have recovered from covid-19 and those who will be vaccinated against the disease in the future.

If a person becomes infected with a new type of coronavirus, they will become immune to it. At least six months, re-infection is unlikely.

This is the conclusion of a new study by experts from Oxford, included in British “first-line” medical personnel.

Cells remember coronaviruses

“This is really good news, because we can be sure that at least in the short term, most people who have suffered from covid-19 will not become infected again,” study co-author David Eyre told Reuters.

Isolated cases of re-infection with covid-19-induced SARS-CoV-2 virus have raised concerns that the recovery of the recovered person is short-lived. However, the results of a British study involving health professionals at risk of infection suggest that these cases are rare.

“We did not see any new symptomatic infections in the study participants who were antibody positive,” said Dr. Eyre.

Therefore, it is assumed that if we get covidium and overcome the infection, the immune system remembers it. When we encounter the virus for the second time, it can react in a timely manner and eliminate the infection before it enters the body, spreads and causes harmful inflammation.

Immunity can be even longer

The study was conducted in a medical staff testing program. Includes data for thirty weeks from April to November. The results are published on the MedRxiv website.

“If we see persistent levels of immune response in humans, it gives us hope that vaccines will not only protect in the short term,” WHO expert Mike Ryan told the study.

During the study, 89 of 11,052 participants who did not have antibodies had a symptomatic coronavirus infection. Of the 1,246 antibody providers who had antibodies, none had any symptoms within thirty weeks.

Participants with antibodies are also less likely to have asymptomatic coronavirus infection. Seventy-six people without antibodies experienced asymptomatic coronavirus infection during the study. Among the participants who detected antibodies, only three asymptomatic infections were reported. None of the three showed symptoms later.

“We will continue to closely monitor the group of workers to see how long the protection lasts and whether the previous infection affects the severity of the course of the infection if people become infected again,” said Professor Air.
