Except insurance literally isn't required to get the vaccine
One could extrapolate from the data uninsured people under the age of 65 are the least likely to be vaccinated for a variety of reasons.
Being under 65 they're at low risk, and if they're uninsured they probably don't have a job (or a job that requires a vaccination).
It's also not unreasonable to imagine that dumb derriere mother fuckers under the age of 65 are less likely to have health insurance. So is it insane to believe that dumb derriere mother fuckers are less likely to get vaccinated?
