The purpose of this study is to evaluate the immunogenicity, safety and reactogenicity of one
dose of four different formulations of the MenACWY conjugate vaccine when given to healthy
children aged 12-14 months and 3-5 years. The selection of the best formulation will be based
on data obtained up to one month after the vaccine dose.
The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep
