Summary

This is an open label and off label, phase IV, randomized clinical trial that will compare the immune response among infants that receive either two full doses of Sabin IPV intramuscularly or two fractional (1/5) dose of Sabin IPV intradermally at 14 weeks and 9 months of age from two different manufacturers.

Detailed description

After OPV cessation, which is expected within a year of polio eradication certification, IPV will be the only polio vaccine used in essential immunization programs. SAGE has recommended a two-dose intramuscular IPV or intradermal fractional IPV (fIPV) schedule after OPV cessation. While it is expected that there shall be sufficient IPV available - in large part because of several manufacturers establishing production of IPV using Sabin strains (sIPV) - it is dependent on these manufacturers being able to meet promised product development and manufacturing timeline and meet WHO prequalification. It is likely that countries that have introduced intradermal fIPV pre-eradication will continue to use intradermal fIPV post-eradication. Therefore, it is important to generate evidence on immunogenicity of intradermal fractional sIPV in addition to intramuscular sIPV for the schedule recommended by SAGE. This clinical trial assesses and compares the immunogenicity of full and fractional (1/5) dose Sabin IPV given at 14 weeks and 9 months of age from two different manufacturers. Healthy infants 6 weeks of age will be enrolled in Dhaka, Bangladesh, and randomized to one of four arms: A. IMBCAMS full dose sIPV at 14 weeks and 9 months B. IMBCAMS fractional dose sIPV at 14 weeks and 9 months C. BIBP full dose sIPV at 14 weeks and 9 months D. BIBP fractional dose sIPV at 14 weeks and 9 months Participants will be followed until 10 months of age through clinic visits. Blood samples will be collected for measuring immune response.
