Once the vaccines come out of emergency use statues, the armed forces and federal employees and contactors will be required to have proof of vaccination. Healthcare providers will charge a premium for stupidity, there will be discounts for the vaccinated, they won't pay for stupid any longer than they have to. Of course private employers, venues and airline travel will POV too. Younger people will be offered cash for the jab and other incentives, also they will get a lot of PSAs and messages from celebrities advocating vaccination.
Joe will just set the wheels in motion and do nothing about the healthcare providers cutting off coverage or charging a big premium on the stupid. They will get those numbers around 80% by fall or there will be more sore assholes than arms by then.
