Four schools on Capitol Hill have student vaccination opt out rates above 10% — breaking the “herd immunity” model — The Seattle Times reports:

At least 86 schools in King and Snohomish counties have a vaccine exemption rate of 10 percent or higher, an analysis of Department of Health data shows. Typically, 90 percent of a population must be vaccinated for highly contagious diseases to achieve “herd immunity” — the point where enough people are immunized to protect those most vulnerable to infection.

The Times report includes a map of the “10%” schools including the Hebrew Academy near Interlaken, Lowell Elementary on E Mercer, and NOVA High School, and the Secondary Bilingual Orientation Center on the Meany campus near 19th and Thomas. You can also view school stats by ZIP Code:

With numbers for all grades shaking out with surprisingly high opt out rates, there are signs that things won’t be improving on the vaccination front anytime soon. In November, CHS reported on the “out of compliance” rates found in Capitol Hill’s public kindergartens.

UPDATE: King County has provided an updated look at school vaccination data that includes some private schools left out of the Times analysis. On Capitol Hill, Bertschi weighs in with only 6% of students not fully vaccinated. But nearby private Bright Water School tallies a whopping 45% of students with incomplete vaccinations.
