Remember that people over the age of 60 and/or infected with Diabetes/Blood Pressure will die when taking the vaccine.

So it will also serve as an inferiority removal mechanism.

But don't worry about it for too long. When the vax is proven to be a goalpost dud, these people will be the first to murder each other on the streets. By that point your only choice is 1. graze a bullet into your head or 2. move to the wilderness.
