Pfizer and BioNTech's Covid-19 vaccine is just 39% effective against delta in Israel, but still provides strong protection against severe illness and hospitalization.
That's what the UK is reporting. Israel vaccinated earlier and the data seems to show that the protection drops off after a few months.
Viral load with Delta is about 1000x as much as previous variants, and the infectiousness is approaching measles territory. How much virus you are exposed to seems to have an impact on how well your body can fight off an infection, so we should all be wearing masks and distancing even if vaccinated. Odds are you'll be fine if you're vaccinated but you can still potentially carry enough of the virus to pass it on.

Good thing we're ready to re enter lockdowns and re impose masking if need be
"I did my part and got vaccinated, I'm done with masks!" :covid-cool:
