Repeated covid? The researchers said how long a person has been immune after an infection

A study by the British Government Health Agency Public Health England (PHE) shows that re-infection with coronavirus in people who have undergone covid-19 and developed antibodies is very rare. Of the 6,614 people, mostly British health professionals who participated in the study, only 44 were re-infected.

However, experts note that according to the results of the study is now The risk of re-infection in people who became infected during the first wave of the pandemic last spring is relatively high. They also mention that people with the immunity they have acquired after covid-19 can transmit the SARS-CoV-2 virus in their nose and throat, and inadvertently spread it.

“There is still a risk that you will catch the virus and pass it on to others”

“It simply came to our notice then most people who have been infected with the virus have developed antibodies and are thus protected from re-infection, but this is not 100%. We also don’t know yet how long the protection lasts, “said Susan Hopkins of PHE, who is a co-author of the study.

“So if you think you have already had an illness and are thus protected, know that you are highly unlikely to develop a serious infection. But there is still a risk that you will catch the virus and pass it on to others,“Hopkins added.”

Experts note that in their study did not investigate antibodies that are formed after administration of covid-19 vaccines. They want to address them in subsequent research. They also want to find out whether the antibodies can last in the body for more than five months after covid-19.
