People who have sought COVID-19 can be repeatedly repeatedly infected with coronavirus in the case of Omicron-strain compared to Delta-strain. This is stated in the study of epidemiologists from the Imperial College of London, reports TASS.
According to scientists, if before the appearance of an Omicron strain in people who have undergone coronavirus infection, natural immunity protected from re-infection for six months in 85 percent cases, then in the event of a new version, this figure decreased to 19 percent.
Currently, no evidence was found that the new version of COVID-19 is a smaller threat than delta strain, given the indicators of infection and hospitalization, the researchers have emphasized.
According to experts, two doses of vaccine from coronavirus infection of Pfizer and its partner Biontech, as well as the British-Swedlen manufacturer of Astrazeneca are able to protect against infection only up to 20 percent of cases against Omicron strain, but it rises to 55-80 percent After booster vaccination.
