Vaccine-preventable diseases disproportionately affect people with poorer overall health. – VoICE
Key Concept

Key Evidence: In a long-term study of Canadian surveillance data researchers found that immunocompromised people were at a 12-fold risk of invasive pneumococcal disease (IPD) compared to healthy people. In addition, the risk of death from IPD in immunocompromised people was found to be 30-80% higher than healthy individuals who had contracted IPD.

Key Evidence: A study of the impact of measles vaccine in Bangladesh found that unvaccinated children in the poorest quintile were more than twice as likely to die as those from the least poor quintile. In addition, vaccination reduced socioeconomic status-related mortality differentials

Key Evidence: An analysis of the association between undernutrition and mortality in young children revealed that in 60% of deaths due to diarrhea, 52% of deaths due to pneumonia, 45% of deaths due to measles and 57% of deaths attributable to malaria, undernutrition was a contributing factor.
