Omicron largely evades immunity from past infection or two vaccine doses

The Omicron variant largely evades immunity from past infection or two vaccine doses according to the latest Imperial modelling. The new report (Report 49) from the Imperial College London COVID-19 response team estimates that the risk of reinfection with the Omicron variant is 5.4 times greater than that of the Delta variant. This […]

Omicron may be less severe in South Africa. That may not be the case for the U.S.

It’s been about a month since scientists first detected the highly mutated coronavirus variant dubbed “omicron.” Since then, scientists have come to learn that omicron spreads faster than the delta variant and is the quickest-spreading variant the world has yet faced. It also has a huge ability to bypass immune […]
