Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an open-label phase IV randomized clinical trial that will compare immune responses among infants who receive different dose schedules of either fractional dose or full dose inactivated poliovirus vaccine (IPV), delivered either intramuscularly or intradermally.

Note: This study was terminated early due to the COVID-19 pandemic. Due to early study closure, the study objectives could not be evaluated as planned. Both of the primary objectives and several secondary objectives could not be evaluated because none of the study participants reached the corresponding endpoint. Due to limited sample size, the analysis approach for four secondary objectives was changed from a non-inferiority assessment to a comparison of proportions between groups.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Oral poliovirus vaccine (OPV) cessation is essential to achieve eradication of polio as OPV contains live poliovirus, which can mutate and become neurovirulent. After OPV cessation, inactivated poliovirus vaccine (IPV) will be the only polio vaccine used for routine immunization. This clinical trial will provide poliovirus type-specific immunogenicity data on an IPV or fractional-dose IPV (fIPV)-only schedule for routine immunization, which will be important for post OPV cessation era. For fIPV, it will provide immunogenicity data on fIPV administered either intradermally (ID) or intramuscularly (IM) and allow a direct comparison of the two methods.

Healthy infants 6 weeks of age will be enrolled at two study clinics in Dhaka, Bangladesh, and randomized to one of seven study arms. Infants will be followed-up until 10 months of age through clinic visits. Blood specimens will be collected to test for immunological response.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Healthy infants 6 weeks of age
* Parents that consent for participation in the full length of the study.
* Parents that are able to understand and comply with planned study procedures.

Exclusion Criteria

* Parents and infants who are unable to participate in the full length of the study.
* A diagnosis or suspicion of immunodeficiency disorder either in the infant or in an immediate family member.
* A diagnosis or suspicion of bleeding disorder that would contraindicate parenteral administration of IPV or collection of blood by venipuncture.
* Acute diarrhoea, infection or illness at the time of enrolment (6 weeks of age) that would require infant's admission to a hospital.
* Acute vomiting and intolerance to liquids within 24 hours before the enrolment visit (6 weeks of age).
* Evidence of a chronic medical condition identified by a study medical officer during physical exam.
* Receipt of any polio vaccine (OPV or IPV) before enrolment based upon documentation or parental recall.
* Known allergy/sensitivity or reaction to polio vaccine, or its contents.
* Infants from multiple births. Infants from multiple births will be excluded because the infant(s) who is/are not enrolled would likely receive OPV through routine immunization and transmit vaccine poliovirus to the enrolled infant. Even if all births from a multiple birth could be enrolled in the study, we will exclude multiple births as discontinuation of one may lead to discontinuation of multiple participants.
* Infants from premature births (\<37 weeks of gestation).
