Marginalized populations derive the most benefit from immunization against rotavirus

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.
