TRIAL DESCRIPTION
Public title PsA-TT-007
Official scientific title A Phase III, double-blind, randomized, controlled study to evaluate the immunogenicity and safety of different schedules and formulations of a meningococcal A conjugate vaccine administered concomitantly with local EPI vaccines in healthy infants and toddlers
Brief summary describing the background
and objectives of the trial
The present study is a schedule evaluation study intended to evaluate the safety and immunogenicity of two different schedules of administration of the PsA-TT vaccine in infants and toddlers with two formulations of Group A Neisseria meningitidis purified polysaccharide - PsA 10µg and PsA 5µg - administered in a one-dose schedule at 9-12 months and in a two-dose schedule at 9-12 months and 15-18 months concomitantly with EPI vaccines, including a second dose of measles and rubella vaccines. Possible interferences with EPI vaccines administered concomitantly will be evaluated.
