Dataset from A Randomized, Observer-Blind, Controlled Phase 1/2 Trial to Evaluate the Safety, Tolerability and Immunogenicity of Different Doses of a Stand-alone Trivalent, Inactivated Poliomyelitis Vaccine From Sabin Strains in Healthy Infants, With a Safety and Tolerability Age-Step Down Lead-in in Healthy Adults Followed by Healthy Toddlers

The purpose of this study is to select the optimal antigen dosage of the three Sabin poliovirus strains (types 1, 2, and 3) entering the composition of the stand-alone trivalent Sabin-based inactivated poliomyelitis vaccine (sIPV) to take forward into advanced stage studies. The selection will be carried out comparing the three sIPV study arms based on the safety and tolerability profile after each dose of primary immunization and the immune response to poliovirus types 1, 2, and 3 for both Sabin and Salk strains, after the final dose of a three dose primary immunization series (Day 85).
