Interesting thread from epidemiologist @kallmemeg. Delta is more severe, but vaccines seem to be slowing its spread, which is occurring mostly in schools and workplaces.
One shining light however is that vaccination still appears to be making an impact on spread
73% of Delta cases are in unvaccinated people
Only 3.7% Delta cases are in people who’ve had both doses pic.twitter.com/zg6Yji76tr
