VoICE Immunization Evidence: Cost effectiveness
Key Evidence: An analysis of the impact of rotavirus vaccine in 25 countries found that the rates of vaccination in all countries were highest and risk mortality lowest in the top two wealth quintile’s coverage. Countries differed in the relative inequities in these two underlying variables. Cost per DALYs averted in substantially greater in the higher quintiles. In all countries, the greatest potential vaccine benefit was in the poorest quintiles; however, reduced vaccination coverage lowered the projected vaccine benefit.

Key Evidence: Children in the poorest 20% of households in Laos have a 4-5 times greater risk of dying from rotavirus than the richest 20%. Consequently, rotavirus vaccination was almost five times more cost-effective in the lowest income groups in the Central Region than in the richest households in the wealthier North region. Thus, rotavirus vaccination has a greater potential for health gains and greater cost-effectiveness among marginalized populations.
From the VoICE Editors: Note that these gains are dependent on improving vaccination coverage, access to health care and environmental health in these populations.

Key Evidence: A study looking at the impact of pneumococcal vaccine introduction and scaling up pneumonia treatment in Ethiopia found that 30-40% of all deaths averted by these interventions would be expected to occur in the poorest wealth quintile. The greatest resulting financial risk protection would also be concentrated among the bottom income quintile.

Key Evidence: A study of measles vaccine in Bangladesh found that children from the poorest quintile were more than twice as likely to die as those from the least quintile in the absence of measles vaccination. The difference in mortality between unvaccinated and vaccinated was statistically significant (p<0.10) and robust across alternative measures of socioeconomic status.
