In the measles zone in the 'hood

By way of the New York Times. Note, the low rate of vaccination is not the consequence of parents opting out via the idiosyncratic "personal belief exemption." The low vaccination rate in the neighborhood school seems a result of new immigration status and poverty.

I would not be surprised to hear that the San Francisco Unified School District contests these numbers; nor would I be surprised if the true percentage is still very high.
