South Africa research shows Omicron variant may scale back Delta transmission

Worldwide in South Africa appears to show that the Omicron variant reduces Delta infections and could also increase immunity in opposition to extreme sickness with Delta. According to a Bloomberg report, the paper was co-authored by Alex Sigal and Khadija Khan from the Africa Health Research Institute in Durban. It has not been peer-reviewed.
The paper also means that being contaminated with Omicron can create increased immunity in opposition to Delta, together with decreasing the chance of severe disease. According to the researchers, while the brand new variant has been shown to spread quickly and may potentially escape some antibodies, immunity to subsequent Omicron infections increased 14-fold around 2 weeks after first creating symptoms with the variant. The report says a smaller enchancment was seen towards the Delta variant.
Sigal has previously reported that 2 doses of the Pfizer Covid-19 vaccine in someone who has beforehand had Covid-19 can boost safety towards the Omicron variant. According to the most recent research, there’s a decreased likelihood of somebody who has contracted Omicron subsequently becoming contaminated with Delta. This would indicate that Omicron could reduce the presence of Delta.
“If we’re fortunate, Omicron is much less pathogenic, and this immunity will assist push Delta out.”
Omicron is now the dominant variant in South Africa however regardless of a surge in circumstances, it has not led to the record hospitalisations previously seen with the Delta variant. The highly-contagious variant is now on its way to becoming the dominant pressure globally..
