Story is about Africa, primarily Somalia. I imagine vaccine hesitancy must be rising in the US as well, but this is about Africa.
Interestingly, our paediatrician in the US gave us a long lecture about why vaccines are important and this and that. He's an older gentleman and wouldn't brook any of my interruptions that I've been through this and to please proceed with the vaccination schedule and that I've had measles[0] when I was a young child and have no intention of subjecting my children to it. Presumably his insistence on the subject was because of hesitancy.
In the end, we got the usual ones but didn't give our daughter the COVID vaccine. I can't say it's a super principled position, except that I think I do want to minimize the number of vaccinations she gets to the ones that are the highest risk for her. That's the usual meningococcal, hepatitis for a neonate; the Tdap for an infant, and the subsequent measles et al. for older children. I think I'm content to leave the tail risk items in the tail.
0: I was eight months old, my parents were the only doctors in the rural Indian village, and consequently a local brought their very sick child to our home. The child was in the room for just a few moments before my mother rushed me to the other room. As it so happened it was too late for me. I became quite sick as well.
