About this trial

The purpose of this clinical trial is to assess the safety and tolerability (primary objective), immunogenicity (primary and secondary objectives), fecal shedding of vaccine viruses (secondary objective) and the potential for neurovirulence of shed virus (secondary objective) of a novel oral polio type 3 vaccine, nOPV3, as compared to Sabin monovalent type 3 vaccine controls (mOPV3), in healthy young children (192 subjects), infants (860 subjects), and neonates (480 subjects).

Eligibility criteria

Qualifiers

Healthy, as defined by the absence of any clinically significant medical condition or congenital anomaly as determined by medical history, physical examination, and clinical assessment of the investigator.

Parent(s) or guardian(s) willing and able to provide written informed consent prior to performance of any study-specific procedure.

Resides in study area and parent(s) or guardian(s) understands and is able and willing to adhere to all study visits and procedures (as evidenced by a signed informed consent form [ICF] and assessment by the investigator).

Disqualifiers

For all participants the presence of anyone under 10 years of age in the participant's household (living in the same house or apartment unit) who does not have complete "age appropriate" vaccination status with respect to poliovirus vaccines at the time of study vaccine administration. For household members younger than 10 years of age appropriate vaccination is complete series of the primary poliomyelitis immunization series for the jurisdiction.

For all participants having a member of the participant's household (living in the same house or apartment unit) who has received OPV based on the vaccination records in the previous three months before study vaccine administration.

Any participating children attending day care or pre-school during their participation in the study until one month after their last study vaccine administration.
