Research by South African scientists tells that omicron neutralizes infection Immunity against delta type of coronavirus.
Study, which has not been peer-reviewed, found that people who were infected with Omicron, especially those who had been vaccinated, developed increased immunity to the delta variant.
The analysis enrolled 33 vaccinated and unvaccinated people who were infected with the Omicron variant South Africa,
While the authors found that the neutralization of Omicron increased 14-fold at 14 days after enrollment, they also found that there was a 4.4-fold increase in delta virus neutralization.
“Increased neutralization of the delta variant in individuals infected with Omicron may result in a reduced ability of delta to re-infect those individuals,” the scientists said.
Alex Sigal, a professor at the Africa Health Research Institute in South Africa, said on Twitter on Monday that if Omicron was less pathogenic as seen from the South African experience, “it would help delta out”.
According to an earlier study from South Africa, people infected with the Omicron coronavirus disease have a lower risk of hospitalization and serious illness compared to Delta One, although the authors say some of them may be at risk due to higher population immunity. is likely to.
The Omicron variant, first detected in southern Africa and Hong Kong in November, has since spread around the world and threatened to disrupt hospitals and travel plans this holiday week.
