Probably some truth to this, similar to other articles claiming conservatives are being weeded out because of their refusal to get vaccinated.
I am vaccinated, but I understand the reluctance of the anti-vax movement. This experiment won't be fully realized until 5 to 10 years from now. I suspect there could be a higher cancer rate of the vaccinated over the unvaccinated, but there won't be any dropping off like flies. Probably a lower death rate than COVID.
But this issue has gone beyond merits of medicine and science. The anti-vaxxers seem not want to give people free choice. This movement is mostly about political power--and control of people not in the "in group."
