The purpose

Globally, polio cases have decreased by over 99% since 1988. However, wild poliovirus cases continue in Pakistan. Conflict and lack of access to children due to on-going insecurity in tribal areas present special challenges in interrupting transmission rapidly. There exists limited knowledge on the effect of shorter intervals of mOPV vaccination on immunogenicity levels in young children. The aim of this study is to demonstrate the non-inferiority of shorter intervals (7 and 14 days) between doses of mOPV1 vaccine compared to the customary interval (30 days). A 4th arm will receive bivalent (bOPV) vaccine at standard intervals beginning at 6 weeks of age.

Provided treatments
