Covid-19: Omicron could help build herd immunity, say South African virologists

JOHANNESBURG: The Omicron variant of the Covid-19 coronavirus could help build herd immunity in societies due to its high transmissibility, South African virologists said on Thursday (Jan 13).

With milder symptoms and lower mortality rates, Omicron differs from other strains, according to scientific data gathered over a 50-day period after the variant was detected in South Africa and Botswana.
