Brief Summary

The background of the present clinical trial is the overall aim of the World Health Organization (WHO) to obtain eradication of polio in the world. As part of this overall plan, inactivated polio vaccine (IPV) against poliovirus types 1, 2 and 3, at an affordable price, needs to be available in low resource third world countries. The intention of the present phase II clinical trial is to determine if reduced dose(s) of IPV-Al SSI are safe in the target population and do not decrease the immunogenicity clinically significantly compared to full dose IPV Vaccine SSI. The infants will receive three doses of one of the trial vaccines according to the WHO Expanded Program on Immunization (EPI) schedule of 6, 10 and 14 weeks of age.

A total of 824 healthy infants will be included in the trial.

Detailed Description

The trial is a phase II, dose investigation, parallel and multi-group, observer-blind, randomised, controlled, multicentre and non-inferiority trial.

Three investigational reduced dose adjuvated IPV-Al SSI vaccines and full dose IPV SSI vaccine will be investigated in four parallel groups:

• 1/3 IPV-Al SSI
• 1/5 IPV-Al SSI
• 1/10 IPV-Al SSI
• IPV Vaccine SSI (comparator)

At Visit 1 (screening and 1st vaccination visit), written informed consent is obtained and the subject's eligibility is assessed according to the pre-specified in-/exclusion criteria, including measurement of axillary temperature. If the subject is included, a pre-vaccination blood sample is taken for polio antibody determinations, and the subject is randomly allocated into one of the four groups to be vaccinated.

The subject is observed for ½ an hour after the injection of the investigational medical product (IMP) and any immediate adverse events observed are to be recorded. A diary, thermometer and ruler are handed out to the parents/guardians so that they can measure daily the injection site reactions and the axillary temperature the first 3 days and record any adverse event until the next visit.

At Visit 2 (2nd vaccination visit), 28-42 days after Visit 1, contraindications are reviewed, the 2nd vaccination is given, the diary is collected and adverse events and concomitant medications are recorded in the eCRF. A new diary is handed out.

At Visit 3 (3rd vaccination and blood sample visit), 28-42 days after Visit 2, a blood sample for immunogenicity assessment is taken, contraindications are reviewed, the 3rd vaccination is given, the diary is collected and adverse events and concomitant medications are recorded in the eCRF. A new diary is handed out.

At Visit 4 (blood sample visit), 28-42 days after Visit 3, a blood sample for immunogenicity assessment is taken, the diary is collected, and adverse events and concomitant medications are recorded in the eCRF. The trial termination form is completed.

5. One parent/guardian is likely to comply with trial procedures

Exclusion Criteria

1. Vaccinated with poliovirus vaccine (OPV or IPV), other than the trial vaccines, prior to inclusion or planned during the trial (e.g. on national polio immunisation days)
