No effects on measles or rubella antibody titers were observed, and significant increases were seen in RV-IgA and RV-IgG seropositivity rates and geometric mean titer (GMT) in Rotarix booster recipients.84 A similar study in Mali was conducted to administer a booster dose of RotaTeq with yellow fever, measles, and meningococcal A vaccines at 9 months. This evidence concerns the gene CD79A and measles.
