Re-infection with coronavirus depends on the individual characteristics of the immune system.
According to RIA Novosti, this was stated by Vladimir Chulanov, chief specialist on infectious diseases at the Russian Ministry of Health.
According to him, re-infection with COVID-19 is very rare.
"Coronavirus re-infection depends on the individual characteristics of the human immune system. For example, a weakened person's immune system may not produce enough antibodies, ”he said.
The World Health Organization does not rule out re-infection with COVID-19.
