India and Nigeria, not California.
Vaccinations and public health are in the news lately, mostly with a focus on the United States. But it's worth taking a look at this map Benjamin Hennig made of where children go unvaccinated on a global basis to help put things in perspective: You can see here that India (the enormous yellow blob) and Nigeria (the large light-orange blog that dominates western Africa) are the two countries that combine very large populations with low immunization rates. The Philippines, Indonesia, Bangladesh, Congo, and Ethiopia also seem like major problem spots. Clearly in most of these places the problem is a lack of financial and institutional resources rather than explicit anti-vaccine sentiment. Insofar as politics are relevant it's in terms of setting priorities.
