After a Debacle, How California Became a Role Model on Measles
In December 2014 something unusual happened at Disneyland. People came to visit Mickey Mouse, and some of them left with measles. At least 159 people contracted the disease during an outbreak lasting several months. This is more than the typical number in a whole year in the United States. The leading theory is that measles was introduced in Disneyland by a foreign tourist. That could happen anywhere. Medical experts generally agree that the fact that it took off was probably a result of California’s low vaccination rates, which in turn was a result of an inability to persuade a significant share of Californians that vaccines were important. The episode made national news, but in the next few years, another development was striking but attracted less national attention: Because of a policy change, California was able to turn it around.
