Brief Summary
This study is part of the post-licensure commitment to evaluate the safety and immunogenicity of Meningo A+C vaccine in healthy Chinese children 2 to 6 years of age. Primary Objective: To demonstrate the non-inferiority in terms of seroconversion rate for serogroups A and C, 30 days after a single dose of Sanofi Pasteur Meningococcal (Groups A and C) Polysaccharide Vaccine versus Lanzhou Institute for Biological Products Meningococcal (Groups A and C) Polysaccharide Vaccine. Secondary Objective:
- To describe the immunogenicity for serogroups A and C, 30 days after administration of the study vaccines given as a single dose.
- To describe the full reactogenicity profile after administration of the study vaccines given as a single dose.

Outcome Measures
Primary Outcomes (1)
Number of Participants With Seroconversion Following Vaccination With Either Sanofi Pasteur Meningococcal A+C Polysaccharide Vaccine or Lanzhou Institute of Biological Products Meningococcal A+C Polysaccharide Vaccine
Seroconversion status was defined as antibody titers against meningococcal serogroups A and C, 30 days after vaccine administration ≥ 4-fold increase from pre-vaccination level measured by 2,3,5 triphenyltetrazolium chloride (TTC) serum bactericidal assay using baby rabbit complement (SBA-BR).
Day 30 post-vaccination
Secondary Outcomes (6)
Percentage of Participants With Post-vaccination Titer ≥1:8 for Serogroup A Before and Following Vaccination of Sanofi Pasteur Meningococcal A+C Polysaccharide Vaccine or Lanzhou Institute of Biological Products Meningococcal A+C Polysaccharide Vaccine
Day 0 (pre-vaccination) and Day 30 post-vaccination
Percentage of Participants With Post-vaccination Titer ≥1:8 for Serogroup C Before and Following Vaccination of Sanofi Pasteur Meningococcal A+C Polysaccharide Vaccine or Lanzhou Institute of Biological Products Meningococcal A+C Polysaccharide Vaccine
Day 0 (pre-vaccination) and Day 30 post-vaccination
Geometric Mean Titers of Serogroup A and C Antibodies Following Vaccination With Either Sanofi Pasteur Meningococcal A+C Polysaccharide Vaccine or Lanzhou Institute of Biological Products Meningococcal A+C Polysaccharide Vaccine

Eligibility Criteria
You may qualify if:
- Informed consent form has been signed and dated by the parent or another legally acceptable representative
- Subject and parent/ legally acceptable representative are able to attend all scheduled visits and to comply with all trial procedures
- Written documentation of immunization history against meningococcal disease according to the national Expanded Program on Immunization (EPI) schedule (including 2 doses with Meningococcal Group A Polysaccharide Vaccine between 6 and 18 months of age).
You may not qualify if:
- Participation in the 4 weeks preceding the trial vaccination or planned participation during the present trial period in another clinical trial investigating a vaccine, drug, medical device, or medical procedure
- Receipt of any vaccine in the 4 weeks preceding the trial vaccination or planned receipt of any vaccine in the 4 weeks following the trial vaccination (except for influenza vaccination, which may be received at least 2 weeks before study vaccines)
- Previous vaccination against meningococcal disease within the past 12 months with either the trial vaccine or another vaccine
- Previous vaccination with any meningococcal conjugate vaccine.
- Receipt of immune globulins, blood or blood-derived products in the past 3 months
- Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy, within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months)
- History of meningococcal infection, confirmed either clinically, serologically, or microbiologically
- At high risk for meningococcal disease during the trial, including:
- persons with increased susceptibility such as persistent complement component deficiencies,
- persons with anatomic or functional asplenia,
- persons who have exposure (e.g., microbiologists routinely working with N. meningitidis, or travelers to or residents of areas where meningococcal disease is hyperendemic or epidemic)
- Known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the vaccines used in the trial or to a vaccine containing any of the same substances
- Known thrombocytopenia, as reported by the parent/ legally acceptable representative, contraindicating intramuscular vaccination
- Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily
- Chronic illness that, in the opinion of the investigator, is at a stage where it might interfere with trial conduct or completion
