Immunity against coronavirus infection creates an extremely low probability of re-infection and infecting others.

It is stored for at least nine months after the disease, Swedish scientists found, quoted by the Swedish National Agency TT.

Doctors from the Carolina Institute and the Daderud Clinic conducted studies with 370 participants who were on the front line and in close contact with the infection.

In 96% of them, after the disease, the presence of antibodies persisted for the next 9 months. And then two-thirds of those mentioned developed cellular immunity.

Among 340 people with antibodies, recurrence of the virus was observed in less than 1% of them.

All participants underwent a coronavirus test every day for 2.5 months.

“Antibodies and cellular immunity are an indirect indicator of immunity, while simultaneous PCR tests are a direct indicator,” explained one of the study’s authors, Dr. Charlotte Tolin.

According to her, in case of repeated illness, the emerging immunity may suppress the symptoms or it may not appear at all.

In this case, a person can be a carrier of the infection, which is the most insidious option. Considered healthy, such a person can transmit the infection to others. But it turns out that this is not the case.

The main conclusion of the study is that the risk of re-infection is insignificant, and those who have it cannot transmit the infection to others.
