Study of Reduced Dose of Menomune® in Children Who Previously Received Meningococcal Diphtheria Toxoid Conjugate Vaccine
Antibody Responses to a Reduced Dose of Menomune® in Children Who Previously Received an Experimental Tetravalent (A, C, Y, and W-135) Meningococcal Diphtheria Toxoid Conjugate Vaccine, TetraMenD
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.

- For the Control group: no previous history of any meningococcal vaccination
- Parent/Guardian has signed Institutional Review Board- (IRB-) approved informed consent form.
- Stage II
- Participant is healthy, as determined by medical history and physical examination.
- Participant is at least 3 years of age but not yet 6 years of age at the time of enrollment in Stage 1.
- Enrolled in the Control group only and received one dose of the reduced dose Menomune at Stage 1.
- Parent/Guardian has signed Institutional Review Board- (IRB-) approved informed consent form.
