Socioeconomic factors and attitudinal beliefs shape worldwide vaccination rates.

Common infectious diseases are in decline thanks to increasing vaccination coverage, but this is a vulnerable triumph: UNICEF reports that nearly 22 million children remained unvaccinated in 2013. A study by de Figueiredo et al. shows two broad indicators at work: one, a suite of socioeconomic factors, and the other, attitudinal beliefs. Their vaccine performance index calls out the countries that are least likely, based on a series of indicators, to meet the Global Vaccine Action Plan target. These countries are largely in sub-Saharan Africa and Southeast Asia, where poor vaccination coverage correlates with a lack of access to water, health care, and education. Active refusal to vaccinate is more likely to occur in European countries.
