When we compared the 28-day and 56-day titers after vaccine administration among the groups (bOPV-only vs bOPV + OCV or OCV-only vs bOPV + OCV), we did not observe any significant difference (P > .05).

Abbreviations: bOPV, bivalent oral poliovirus vaccine; OCV, oral cholera vaccine; OPV, oral poliovirus vaccine.
