I know some who don't want to be vaccinated, but I also know many who can't get a shot yet.Texas lifted all restrictions when less than 40% got even 1st dose and their stats greatly approved.
I personally don't know anyone 18+ in GTA who wasn't able to get vaccine. But I know a lot of people who just doesn't want to be vaccinated ... maybe this is the reason 3K new cases/day?
It's important to note that Texas is culturally different, and it matters which 40% got the shot.
Also it takes 2-3 weeks for the vaccine to become effective, many people are still in that window.
