Well we are still behind the 8 ball with millions still unvaxed the first round.
Giving booster shots to those who are vaxed and running out?
How do we know the booster shot will last or slow down Delta?
So sit and wait for "them" to get their act together and figger out what to do which they clearly don't know at te moment.
Our lives are in danger but what's the hurry? Why worry?
