South Africa study reveals Omicron variant could scale back Delta transmission

A scientific paper in South Africa appears to point out that the Omicron variant reduces Delta infections and will also increase immunity towards 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 It has not been peer-reviewed.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 suggests that being infected with Omicron can create elevated immunity towards Delta, including reducing the chance of severe illness. According to the researchers, whereas the model new variant has been shown to unfold rapidly and might doubtlessly escape some antibodies, immunity to subsequent Omicron infections elevated 14-fold round 2 weeks after first developing symptoms with the variant. The report says a smaller enchancment was seen in opposition to the Delta variant.
Sigal has beforehand reported that 2 doses of the Pfizer Covid-19 vaccine in someone who has beforehand had Covid-19 can boost safety in opposition to the Omicron variant. According to Strange , there is a decreased likelihood of someone who has contracted Omicron subsequently changing into infected with Delta. This would indicate that Omicron could cut back the presence of Delta.
“If we’re fortunate, Omicron is 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 report hospitalisations previously seen with the Delta variant. The highly-contagious variant is now on its approach to becoming the dominant pressure globally..
