Kinetic of Immune Memory Response After Re-Vaccination With Meningococcal Vaccine

December 2, 2005 updated by: Chiron Corporation

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®

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
