65% efficacy for delta - ROFL.
This guys reckons closer to zero.

A vaccine can even delivery zero immunity but still be high in efficacy if it greatly diminishes acute symptoms.
Almost no vaccine in history offers 65% immunity, or even 50% immunity, but that doesn't mean that they aren't delivering 65% or greater efficacy.
The way this is reported in social media alludes to some controversy, but there isn't and it could be the case that if they are measured the same way AZ and Pfizer are equal in efficacy. However there is a debate going on asking for global standards for measuring efficacy.
