Oregon lawmakers killed a bill at getting more children vaccinated for measles. Despite passing the House and having the necessary votes in the Senate, the measure to make it harder for families to opt out of required vaccinations was nixed. Under the vaccination measure, children would only have been being able to forgo vaccine requirements with a doctor’s note, otherwise, they’d be unable to attend public school. Oregon has the highest rate of unvaccinated kindergartners in the country, with at least 7.5% of toddlers claiming an exemption. In some schools, more than 40% of children are unvaccinated through the state’s lax exemption process. Oregon is one of 17 to allow families to opt out of required school vaccinations for personal, philosophical or religious reasons. It is unclear why lawmakers decided to kill the bill.
