Thanks, Anti-Vaxxers: Many Oregon Schools Have Nonmedical Vaccine Exemption Rates Over 50 Percent

The state of Oregon allows quite literally anyone — whether they believe that illnesses are a blight directly from Satan to humanity and God will heal those who have enough faith, or that vaccines are part of a globalist world depopulation scheme, or even if they believe that vaccines are directly linked to autism in order to opt-out of the requirement that their precious little snowflakes be properly inoculated before attending school — a frighting number of parents are taking advantage of the opportunity to place their children (and others) at risk.
A whopping thirteen schools in the state have Nonmedical Exemption Rates above 50 percent, with some schools hovering at around 70 percent of students who are not vaccinated adequately.
