简要总结
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.
详细描述
This was a two stage, controlled, open-label trial. Stage I of the trial simulated meningococcal challenge Stage II of the trial evaluated the meningococcal vaccine naïve participants from Stage I, who had also received a reduced dose of Menomune® vaccine in Stage I and were administered a full dose of Menactra® vaccine 6 months later.
