  • A randomized controlled trial was conducted in 395 infants aged 9-12 months to determine the effect of Vitamin A supplementation on concurrently administered measles vaccine. Antibody response was measured using the plaque reduction neutralization assay. No statistically significant differences were demonstrated between the immune response in Vitamin A supplemented and unsupplemented children. Unlike some recent studies, we were unable to demonstrate an immune enhancing effect of Vitamin A supplementation. On the contrary, among children who were given Vitamin A, a lower, but statistically non-significant, proportion had protective antibody levels 6 months after vaccination.
