There's a lot of truth to this.
The people who watch Fox News are older and most of them are vaccinated, which is funny when you have hosts spewing anti-vaxx content.
Percentage wise latino & black communities are the least vaccinated and they skew heavily democratic.
Most aren't the crazy anti-vaxxers you hear about though (microchipping, population control) rather it's more about being concerned about its safety as well as the side effects.
I think full FDA approval could make them feel safer.
