Brief Summary:
The purpose of this study is to determine when a memory immune response after re-vaccination with Meningococcal C conjugate vaccine (Menjugate) or challenge with Meningococcal A/C polysaccharide vaccine can be observed, after initial vaccination with Meningococcal C conjugate vaccine during the UK immunization campaign

Condition or disease Intervention/treatment Phase
Meningococcal Disease; Meningococcal Meningitis Biological: · Meningococcal C conjugate vaccine; Meningococcal A/C Polysaccharide vaccine (partial dose) Phase 4

Study Type : Interventional  (Clinical Trial)
Enrollment : 264 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: A Phase IV, Single Center, Open-Label, Controlled, Randomized Study to Evaluate the Memory Response of Children Previously Vaccinated With Chiron Meningococcal C Conjugate Vaccine, Menjugate® and Describe the Kinetic of the Antibody Response and Maturation on Days 2-7 and 28 After Challenge With Pasteur Merieux Meningococcal A/C Polysaccharide Vaccine or Menjugate®
Study Start Date : September 2003

Primary Outcome Measures :
  1. To measure immunological memory response to N. meningitidis serogroup C after those who received a partial dose of Meningococcal A/C Polysaccharide vaccine and in subjects who received a dose of Chiron Meningococcal C conjugate vaccine.

Secondary Outcome Measures :
  1. To assess the immunological response to N. meningitidis serogroup C in those challenged with meningococcal A/C polysaccharide vaccine and in those who received a dose of Chiron Meningococcal C conjugate vaccine.
