Key Concept

Key Evidence: A study modeling the economic impact of 10 childhood immunizations in 41 low- and middle-income countries found that the bulk of poverty averted through vaccination occurs in poor populations. For most of the vaccines in the study, at least 40% of the poverty averted would occur in the poorest wealth quintile. Particularly for pneumonia, more than half of the two million deaths averted by pneumococcal and Hib vaccines would occur in the poorest 40% of the population.
