This was also interesting, from the link you provided...

Health officials would not be as concerned about the average PBE rate statewide — but the rate hides clusters where PBE rates are significantly higher. In the Bay Area there are geographic clusters of vaccine refusals above 10 percent.
Right now, California health officials are working to contain a measles outbreak that has reached 91 cases this month.
After nearly a decade of low PBE rates in the 1990s, they started to increase in 1998. That was the same year a study was published that claimed a link between the measles, mumps, rubella vaccine and autism. The study was later debunked and retracted.
But the damage was done. PBE rates have climbed steadily ever since, until now.
