> CDC says vaccines are only 66 percent effective at preventing Delta infection

WITH A 95% CONFIDENCE INTERVAL OF 26% TO 84%

They only statistically modeled how much their unvaccinated population was already recovered from coronavirus based on estimates of community spread, among other issues with that number.

And when you have a CI of something like that size, of course you wind up in the middle of it -- the actual value could very well be closer to 80% due to systematic uncertainties in the modeling.

Or 30%, to be fair.

published on the CDC site today: 77% (74%-80%) VE for pfizer and 92% (89%-93%) VE for moderna. With only some evidence of reduced VE against delta and/or waning in those > 75 years old:

That's a very reassuring result, thanks for sharing.

Interesting that moderna continues to do better, and looking forward to seeing the studies VE versus time since vaccination.
