This week, J. reported on how Bay Area Jewish day schools are trying to increase their vaccination rates in the wake of the measles outbreak.

Shortly after we went to press, more measles news broke: A LinkedIn employee who had measles traveled on BART during commuting hours on Feb. 4, 5 and 6 potentially exposing thousands of BART riders to the illness.
