A passing thought...
We as homo sapiens differ by a tenth to a hundredth of one degree and compared to Chimps differ by 1 full percent.
This not a scientific observation but I have a question that a diversty of 24% of us refusing vaccination has an effect on the species at large. Pandemics have changed us before in terms of those more suited for survival. 24% of us are not dying off but perhaps in a smaller way our DNA will have changes that would not appear without pandemic. Exogenetic factors could in be in play as well as ancient genes turning on or off. We are not seeing a subspecies going extinct but we may be changed in ways as a species we may not know.

26 million kids 5-11 in the US are to be vaccinated. A quarter of them will not get the shot as a result of parental opinion.
