> He's right in a way, being vaccinated keeps you out of hospital, but it won't prevent you that much from catching the disease and developing post-covid syndrome

This is misinformation.

From the data we have available, vaccination prevents at least 80% of symptomatic infections with the Delta variant.

To characterize an 80% reduction in risk as “not that much” is simply trying to get people to give up on vaccines.

[HarryHirsch]

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%).”
