A perfectly predictable result, based on anecdotal observations of the arguments that I’ve observed on the internet.

The study found that the number of medical exemptions was relatively low during the seven years of the study period, but the rate was more than 6X higher in states with relatively easy medical exemption criteria when compared to states with more difficult exemption standards. As I reported previously, as more parents get vaccine exemptions, herd immunity can be impacted, and children in schools with low immunization levels can face outbreaks of diseases that were once thought rare.Read More »Make vaccine exemptions more difficult to obtain
