Outcomes
Primary outcome [1] 286630 0
A schedule of two doses of mOPV1 administered at a 7 or 14 day interval following a previous mOPV1 dose administered at 42 days induces comparable levels of seroconversion against poliovirus type 1 compared to a schedule of two doses of mOPV1 given at a standard interval of 30 days apart
Timepoint [1] 286630 0
102 days after study enrollment
Secondary outcome [1] 296327 0
A schedule of two doses of mOPV1 administered at a 7 or 14 day interval following a previous mOPV1 dose administered at 42 days induces comparable levels of seroconversion against poliovirus type 1 compared to a schedule of two doses of bOPV1&3 administered at a standard interval of 30 days apart.

Eligibility
Key inclusion criteria
Infants born healthy (> 2.5 kg birth weight, immediate cry, no neonatal IMCI danger signs) at the study sites (home or health facility births assisted by study-Trained Birth Attendants/other health personnel) and not planning to travel away during entire the study period (birth-102 days).
Minimum age
0 Days
Maximum age
0 Days
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
High-risk newborns will be excluded, as well as newborns requiring hospitalization, birth weight below 2.5 kg, cry >2 minutes, and with any neonatal IMNCI danger signs, residence >30 km from study site, or family is planning to be absent during the birth - 102 day study period. A diagnosis or suspicion of immunodeficiency disorder (either in the participant or in a member of the immediate family - e.g. several early infant deaths, household member on chemotherapy) will render the newborn ineligible for the study.

Summary
Brief summary
In order to generate data on 2-dose seroconversion with short interval monovalent OPV1 administration, and standard interval monovalent OPV1 and bivalent OPV (1&3) administration, we will assess additional programmatic options for short-interval SIA rounds in Pakistan and conduct a clinical trial in Karachi, Pakistan where immunogenicity of supplemental mOPV doses in a naive population (newborns) needs objective evaluation.
