How the risks of re-infection with Omicron and Delta strains differ

The probability of re-infection after contracting the Omicron coronavirus strain is five times higher than during the Delta outbreak.

This is the opinion of scientists Imperial College London.

According to the researchers, the immunity of those who had been ill with the Delta variant was able to protect against re-infection in 85% of cases within six months. In the case of Omicron, the rate fell to 19%.

Scientists also concluded that a full course of vaccination will help protect against infection with the new South African strain in 20% of cases.
