Usually, about when there is something in the news about an outbreak around here, I’ll go to the state Department of Health and find out what the vaccination rates are at our local schools (and here). This time around, there is a measles outbreak just about an hour south of us, so I thought it would be nice to narrow in specifically on exemptions (personal, religious or health) for the measles, mumps, rubella vaccination.
According to the most recent data, there are a handful of schools in the Olympia area with fairly high exemption rates for the MMR vaccine.
If you’re new to this issue or just need some background, here is some information you might find useful:
You’ve heard about herd immunity, or how the vaccination rate in a group of people that protects people who can’t receive a vaccine. This is why a 16 percent exemption rate at ORLA or a 12 percent exemption rate at Lincoln are sort of scary.
According to the CDC, an immunization rate of 94 percent is necessary to prevent pertussis from persisting in a community. That is above the 88 percent that the exemption rate at Lincoln would indicate is that school’s immunization rate.
