Rotavirus serum IgA immune response in children receiving rotarix(R) co-administered with bOPV or IPV

Vaccine schedules including bivalent oral (bOPV) and inactivated (IPV) poliovirus vaccines will replace trivalent OPV (tOPV) in 2016. We evaluated rotavirus IgA seroresponses when the second dose of Rotarix(R) at 16 weeks was given concomitantly with IPV or bOPV. Rotavirus IgA seroresponse rate at week 28 was 15% lower in bOPV compared to IPV recipients.
