California’s youth vaccination efforts appear to have worked

Some of California’s efforts aimed at keeping kids up to date with their vaccinations seem to have worked, according to a new study. Since 2014, California has passed two laws to restrict personal exemptions for vaccinations and implemented a campaign to better educate school staff on admitting kids who weren’t up yet to date on vaccinations. Following those measures, more kindergarteners were caught up on their vaccinations than in 2013: Nearly 10% in 2013 were missing some of the required shots, and that number dropped down to less than 5% in 2017. The study only included schools with 10 or more students, however, which could be a limitation because schools with fewer students tend to have the most kids without the necessary vaccinations.
