Details and patient eligibility

About

PR5I, a hexavalent pediatric combination vaccine is being developed to reduce the number of injections during the first 2 years of life while providing a complete course of immunization against infection caused by H. influenzae type b, hepatitis B virus, Corynebacterium diphtheriae, Clostridium tetani, Bordetella pertussis, and poliovirus types 1, 2, and 3.

Primary Objective: To evaluate immunogenicity of PR5I with the adjuvant composition enhancement to the hepatitis B component when administered concomitantly with Prevnar®

Secondary Objectives: To assess the safety and immunogenicity of PR5I when administered concomitantly, or one month apart with Prevnar® or separately with licensed vaccines used for routine infant vaccination in Canada.
