People over 65 are more likely to get COVID-19 again after a previous illness, a new study published in the scientific journal Lancet noted.

According to RIA Novosti, the level of protection against re-infection in patients with COVID-19 infection is 80.5%, but among patients over 65 years old, it drops to 47.1%.

The authors of the study noted that the results obtained once again highlight the importance of measures to protect older people during a pandemic: first of all, we are talking about distance and priority of their vaccination.

Experts say that not a single patient who has had COVID-19 is immune from re-infection with the coronavirus - the same or a different strain.
