Title: A Phase 4, Randomized Study to Evaluate the Safety and the Humoral and Intestinal Immunogenicity of One or Two Additional Doses of Licensed Inactivated Polio Vaccines (IPVs) in Latin American Infants Previously Vaccinated With Bivalent Oral Polio Vaccines (bOPVs)
Brief Summary: This study is a Phase IV, open, randomized, multi-center, controlled vaccine trial conducted in healthy Latin American infants, utilizing one or two supplemental doses of IPV in children previously vaccinated with 3 doses of bOPV. We will examine the impact of supplemental IPV on stool shedding and humoral immunity, as well as intra-IPV manufacturer comparability, and safety.

The following condition is temporary or self-limiting, and a subject may be vaccinated once the condition has resolved and if no other exclusion criteria are met:

• Current febrile illness or axillary temperature \> 37.0 ºC or other moderate to severe illness within 24 hours of study vaccine administration.
C: Inclusion Criteria:

1. Age: 8 weeks (-7 to +7 days).
2. Healthy infants of all ethnicities and both genders without obvious medical conditions that preclude the subject to be in the study as established by the medical history and physical examination.
3. Written informed consent obtained from 1 parent or legal guardian who, in the opinion of the investigator, is capable of understanding and complying with the protocol requirements.

Exclusion Criteria:

1. Previous vaccination against poliovirus.
2. Low birth weight (BW \<2,500 grams).
3. Twins or multiple pregnancy infants.

5. Any confirmed or suspected immunosuppressive or immunedeficient condition including human immunodeficiency virus (HIV) infection.
6. Family history of congenital or hereditary immunodeficiency.
7. Major congenital defects or serious chronic illness (neurologic, pulmonary, gastrointestinal, hepatic, renal, or endocrine).
8. Known allergy to any component of the study vaccines.
9. Uncontrolled coagulopathy or blood disorder contraindicating intramuscular injections.
10. Administration of immunoglobulins and/or any blood products since birth or planned administration during the study period.
11. Subject who, in the opinion of the Investigator, is unlikely to comply with the protocol or is inappropriate to be included in the study for the safety or the benefit-risk ratio of the subject.
D: Inclusion Criteria:

1. Age: 6 weeks (-7 to +14 days).
2. Healthy without obvious medical conditions that preclude the subject to be in the study as established by the medical history and physical examination.
3. Written informed consent obtained from 1 or 2 parents or legal guardian as per country regulations

Exclusion Criteria:

1. Previous vaccination against poliovirus.
2. Low birth weight (BW \<2,500 gm).

7. Known allergy to any component of the study vaccines.
8. Uncontrolled coagulopathy or blood disorder contraindicating intramuscular injections.
9. Administration of immunoglobulins and/or any blood products since birth or planned administration during the study period.
10. Acute severe febrile illness at day of vaccination deemed by the Investigator to be a contraindication for vaccination.
