In its weekly epidemiological report, Tedros Adhanom-led WHO said more data was needed to assess the severity of the Omicron variant and whether its mutations may reduce protection from vaccine-derived immunity.
“Even if the severity is equal or potentially even lower than for Delta variant, it is expected that hospitalisations will increase if more people become infected and that there will be a time lag between an increase in the incidence of cases and an increase in the incidence of deaths,” it said. — Reuters
