(B1) Simulating measles outbreaks in legislators’ cities a sometimes successful tool for vaccine policy change

I will discuss the increasing problem of non-medical vaccine exemptions in US, which permit unvaccinated children to attend schools. We used population and school-level data to create simulations of measles outbreaks in cities, allowing us to forecast the size of measles outbreaks from small decreases in vaccination rates. The simulations communicate the risks of falling vaccination rates in an intuitive manner that can be personalised to city of the viewer. I will show examples of our measles simulations and discuss how they have helped change the vaccine exemption law in California, but not in Texas.
