This report on a recent outbreak of mumps in the US midwest makes the point that the US has a far more stringent and effective system of universal vaccination than most European countries. For example, it’s impossible for a child to attend school without up-to-date vaccination records (at least that was my experience when I lived there).
Australia dropped the ball on this a decade or so ago when the Keating government (IIRC) passed responsibility to the states, but now seems to have restored effectively universal vaccination.
All of this is surprising to me. I would have expected that health scares about vaccination would be at least as easy to run up in the US as anywhere else, that objections on the grounds of individual liberty would be taken more seriously in the US than elsewhere, and that the complex patchwork of state and local management of health policy would lead to large gaps.
Is my general expectation wrong, or is there something special about the case of vaccination? Or is thus just an illustration of the fact that every predictive model fails sometimes?
