Decline in diarrhea mortality/admissions after routine childhood rotavirus immunization in Brazil

In 2006, Brazil began routine immunization of infants <15 wk of age with a single-strain rotavirus vaccine. The researchers evaluated whether the rotavirus vaccination program was associated with declines in childhood diarrhea deaths and hospital admissions by monitoring disease trends before and after vaccine introduction in all five regions of Brazil with varying disease burden and distinct socioeconomic and health indicators.
