You see papers claiming an effectiveness against symptomatic infection against Delta of ~ 50 %, and the rise of cases in Israel as well as the Provincetown outbreak should really make us concerned.

The vaccine still prevents hospitalization and death, so that's reason enough to take it. But on its own it isn't enough to get R_0 below 1. The way everyone is behaving, they are asking for outbreak after outbreak.

Yes, it’s at 47% now if I’m up to date.

Wasn't it up around 75% in Providence RI? Yes, an outlier but it's indicative of the potential.

Guess it’s 42% for Pfizer according to this preprint.[1] That’s July, so presumably even lower now. I thought I saw 47% somewhere more official but can’t find it now.

“ However, in July, the effectiveness against infection was considerably lower for mRNA-1273 (76%, 95% CI: 58-87%) with an even more pronounced reduction in effectiveness for BNT162b2 (42%, 95% CI: 13-62%).”
