Some little municpal health department near Vernal, Utah, was trying to figure out how to up the vaccination rate. The vaccination cost $25. A personal belief exemption involved ticking a box on a form.
Well, a local live wire figured they should reverse the incentives. They made the vaccination free and charged $25 for administrative costs to fill out a more time-consuming exemption form.
Presto, vaccination levels shot up into herd immunity levels (above 95%) and the problem was solved.
What struck me about this story that I heard from a relative is how little it took for people to decide their deeply held personal beliefs were totally negotiable.
Add to that the entirely justifiable costs of billing anti-vaxxers for all the contact tracing and unnecessary medical expenses incurred by their BS, and I bet you could get vaccination rates back up where they belong.
