An Early Glimpse at the New Omicron Subvariant
Vidcast: https://youtu.be/XUOPZr7ayIo
The new version of Omicron, a sub variant known as BA2 or “Stealth Too” that I call Omicron2 or O2 popped up in Denmark and quickly outpaced Omicron1 there. That’s because scientists estimate that O2 is 35-50% more contagious than O1. The good news is that O2 doesn’t seem to trigger more severe disease in humans but it is early. As of this week, O2 has now been detected in at least 29 states and in 56 countries.
A British analysis concludes that our current vaccines work about as well and slightly better on O2 as they do on O1. The booster is 70% effective in preventing a symptomatic O2 infection compared with 63% for O1.
More to come.
