For years I’ve been reporting on vaccination rates in public schools. In June I examined California’s latest data set and reported on how the state’s efforts to stop parents from skipping their kids’ vaccines just led parents to find another loophole to avoid the shots. At one school in rural California, two-thirds of kindergarteners received a medical exemption — essentially a doctor’s note stating their kids shouldn’t get vaccinations — that allowed them to skip immunizations.
I also used a state database to plot immunization rates by zip code; click here for the bigger map.
This piece followed research I did for a WIRED print story about the measles outbreak in Brooklyn, for which I mapped vaccination rates nationwide and plotted the cities most at risk of a measles outbreak.
