Immunity from COVID-19 lasts only six months, re-infection is also possible

Scientists continue to study coronavirus infection and the disease called COVID-19. A study recently appeared in which 13 experts from the Netherlands took part. They examined the medical records of ten patients who contracted at least one of the “seasonal coronaviruses” for 35 years from 1985 to 2020.

Based on the data obtained, the scientists concluded that the immunity in these cases lasted too short, repeated infections were recorded 12 months after the initial infection. And six months later, a significant decrease in antibody levels was observed.

Researchers suggest that the presence of an “immune passport”, which is offered to give patients with COVID-19, will “expire” six months later, since the chances of catching a new coronavirus will increase dramatically. Experts also doubt the effectiveness of the so-called “collective immunity.” It is highly likely that to confront the new coronavirus, a seasonal vaccine will be required, and not a one-time one.

Meanwhile, France has banned the use of an antimalarial drug, which was called a panacea for the treatment and prevention of COVID-19. The country took such a step after the WHO suspended trials of hydroxychloroquine due to negative side effects.
