Immunogenicity and Safety Study of an INvestigational Quadrivalent Meningococcal Conjugate Vaccine when Administered Concomitantly with Routine Pediatric Vaccines in Healthy Infants and Toddlers
The main purpose of this study is to find out if the MenACYW conjugate vaccine is safe and can protect young children against meningococcal disease when it is given at the same time with the childhood vaccines recommended in the US. MenACYW vaccine will be compared to a US-licensed meningococcal vaccine called Menveo. A licensed vaccine is one that a doctor can prescribe. The licensed vaccine protects against meningococcal disease caused by 4 types of germs (A, C, Y and W). The study is also looking at how well the childhood vaccines work when they are given together with the MenACYW investigational vaccine or Menveo.
