The effect of nutritional status on protective efficacy of a live attenuated human rotavirus vaccine (RIX4414) was studied. Vaccine protection was evaluated through a secondary analysis of data from an efficacy study conducted in Brazil, Mexico, and Venezuela. Vaccine efficacy against rotavirus gastroenteritis (RVGE) was similar in well-nourished and malnourished infants: 74.1% (95% confidence interval [CI], 52.2%-86.2%) and 73% (95% CI, 11.2%-92.3%) for severe RVGE and 60.9% (95% CI, 37.4%-75.4%) and 61.2% (95% CI, 10.4%-83.1%) for RVGE of any severity, respectively. RIX4414 significantly decreased the rate of RVGE regardless of nutritional status, which suggests that this patient group can also benefit from rotavirus vaccination.
