Study of Reduced Dose of Menomune® in Children Who Previously Received Meningococcal Diphtheria Toxoid Conjugate Vaccine

This study was designed to simulate meningococcal challenge by vaccination with a fractional combined dose of unconjugated meningococcal polysaccharides A, C, Y, and W-135, Menomune® in children who were vaccinated with one dose of TetraMenD at least 18 months earlier. Primary Objective: To evaluate and compare the antibody responses to a reduced dose of Menomune® in participants who had previously received a tetravalent meningococcal diphtheria toxoid conjugate vaccine to those responses in participants who received the same reduced dose of Menomune® but had not previously received any meningococcal vaccine.
