In the UK and Israel, children (I think ages 5 to 14) is the group with the highest increase in cases due to delta. So far, in Israel with 80% of adults fully vaxxed, there is a surge in cases but no increase in hospitalizations and deaths.

The UK reporting Pfizer (2 shots) confers 96% protection against hospitalizations from the delta variant.

I'm just worried the unvaxxed is gonna keep transmissions up long enough to the point where there is a variant that evades our current vaccines.

Did you hear about the case in Australia in the Bondi Junction Westfield mall? Hopefully, it's just an extreme, extreme outlier, but an Australian health official says in that instance it looks like Delta was transmitted after only 5 to 10 seconds of exposure. Like, they only walked past each other since they were signing in at different places 65 feet apart.
