A friend of mine can't because she's immunocompromised. Their family has done their part by staying home and finding new activities for their kids to accomplish in the house (which, fortunately for them, is pretty easy because they're huge nerds and aren't hurting for money). They're lucky because her husband is a self-employed remote contractor and she is a remote special education teacher.
Immunocompromised people (as a group, many of whom can get vaccinated anyway) generously make up ~3% of the total population. What is the other 22% of the aforementioned 25% doing? There’s no need to point to exceptions when there is a much bigger unexplained group, it just gives them undue plausible deniability.
The remainder is split into two groups: those who are politically aligned in a way that they will thump their chests and proclaim their superiority over COVID like it's some sort of candidate they can defeat, and those who have an anxiety issue over doctors and needles or are afraid that perhaps the ones who are anti-vaxx might be right due to some personal educational deficiency.
