NCT01764126

Brief Summary

This is an observer-blind, randomised, vaccine-controlled, vaccine trial to determine the safety and immunogenicity of a pneumococcal protein vaccine. It will use an age step-down approach beginning with adults, then toddlers then infants, with data safety review at each stage before stepping down to the next age group. Adults and toddlers will receive the same dose of this three-protein (trivalent) vaccine (PcpA, PhtD, and PlyD1 proteins) at 50µg each. Infants will then be started at a low dose (10 µg), then medium dose (25µg) then high dose (50µg), with safety reviews at each stage before ascending to the next highest dose. Infants will also receive concomitant standard EPI childhood vaccines. Safety will be assessed by close monitoring beginning on the day of vaccination (day 0) and for the subsequent seven days, with recording of solicited and non-solicited adverse events. Immunogenicity will be assessed by specific antibody response to the three proteins. The study aims to recruit 280 study subjects across all age groups.
