You're very right. Berkeley was the heart of the whole anti-vax movement a few years ago. So much so that I felt safer taking my (then newborn) to Eastern Europe than taking her to Berkeley.

But if you dig into the data, it's only one zip code in Berkeley with a high vax rate -- the wealthiest part of Berkeley up in the hills, which are mostly older people.

The zip code with all the students is one of the lowest in the state.
