They did a prospective study of vaccine effectiveness vs infection and transmission among vaxxed healthcare and frontline workers. Seems biased from the start. Won’t it be confounded by their tendency to wear (better) PPE?

Edited to add: I suppose it depends on their methodology. Quick glance at Thompson’s study, seems they compared vaxxed HCWs to unvaxxed HCWs. I don’t know if we would expect to see material PPE-wearing differences between those groups.

"Acknowledge the war has changed"

Maybe it has? For example, DC has reported 11 homicides since its last reported COVID death.

Slide 21

>Given higher transmissibility and current vaccine coverage, universal masking is essential to reduce transmission of the Delta variant

Well that's very sad, if not entirely unexpected. How long will we be living in a masked world?

Perhaps they don’t want you to contact or question the federal employee that wrote the document.

This virus will be here for eternity. It's a plot point in our story.

I know I'm tired now. When I read your "masked world", I heard it to the tune of REM's "Mad World"

If you know the effectiveness of PPE vs no-PPE, and the effectiveness of PPE w/ Vaccine vs PPE w/o Vaccine, you can estimate the effectiveness of the Vaccine alone, even if you don't have statistics for it by itself.
