December 5, 2023 updated by: Sanofi Pasteur, a Sanofi Company

A Phase III, Partially Modified Double-blind, Randomized, Parallel-group, Active-controlled, Multi-center Study to Compare the Immunogenicity and Describe the Safety of MenACYW Conjugate Vaccine and MENVEO® When Administered Concomitantly With Routine Pediatric Vaccines to Healthy Infants and Toddlers in the United States

The purpose of this study is to compare the immunogenicity and describe the safety of MenACYW conjugate vaccine and MENVEO® when both are administered concomitantly with routine pediatric vaccines to healthy infants and toddlers in the US.

Study Overview

Detailed Description

The duration of each subject's participation in the trial will be approximately 16 to 19 months (Subgroup 1a) and 19 to 22 months (Subgroup 1b and Group 2), which includes a safety follow up contact at 6 months after the last vaccinations.
