I was listening to a psychology podcast about how to get people to take the vaccine and you’re not far off. Basically market it differently to different groups. Conservatives tend to have lower threshold for things that gross them out, so remind them that germs are bad and vaccines are hygienic. Also don’t underestimate the power of military/cops getting their vaccines on FB Live or whatever. Saturate their feeds with “heroes” who get the poke and they will want it too.
