入选标准
- •Healthy children between 12 months and 15 months old inclusive who were born with an estimated gestational age ≥ 37 weeks.
- •Parent(s)/legal guardian(s) had given written informed consent after the nature of the study had been explained according to local regulatory requirements.
- •Parents/legal guardian available for all the visits and would comply with the requirements of the protocol (e.g., completion of the Diary Cards, availability for study visits / safety phone calls).
- •In good health as determined by the outcome of medical history, physical examination and clinical judgment of the investigator.
排除标准
- •Previous confirmed or suspected disease caused by N. meningitidis.
- •Previously exposed to clinically proven meningococcal disease or clinical bacterial meningitis without further microbiologic characterization, i.e. possible meningococcal disease.
- •Previously immunized with a meningococcal vaccine or vaccine containing meningococcal antigen(s) (licensed or investigational).
- •Received within 90 days prior to enrollment or were expected to receive during the study period any investigational or non-registered product (drug or vaccine).
- •Received or planning to receive any vaccines within 14 days before and 30 days after administration of the study vaccine (Exceptions: Injectable influenza vaccine could be administered up to 14 days prior to study vaccination and at least 14 days after study vaccination).
- •Major congenital defect or a serious chronic disease.
- •History of any anaphylaxis, severe vaccine reactions, or allergy to any vaccine components including diphtheria toxoid (CRM197) or tetanus toxoid (TT) and latex.
- •Required chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within six months prior to the study vaccination. (For corticosteroids, this means prednisone, or equivalent, ≥ 0.5 mg/kg/day. Inhaled and topical steroids were allowed).
- •Receipt of immunoglobulins and/or any blood products within six months prior to study vaccination or who had administration planned during the study period.
- •Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
- •Any bleeding disorder which was considered as a contraindication to intramuscular injection.
- •Moderate or severe acute infection and/or fever (defined as temperature ≥ 38°C) within 3 days prior to enrollment.
- •Systemic antibiotic treatment within 7 days prior to enrollment.
结局指标
主要结局
Number of Subjects With at Least One Severe Solicited Adverse Event (AE) After Receiving One Dose of Either MenACWY-CRM Vaccine or MenACWY-TT.
时间窗: Day 1 to Day 7 post-vaccination
Reactogenicity of MenACWY-CRM and comparator MenACWY-TT vaccine was assessed in subjects (12 to 15 months old) as measured by number of subjects with at least one severe solicited AE within 7 days after vaccination. Solicited AEs included tenderness, erythema, induration, irritability, sleepiness, change in eating habits, vomiting, diarrhea and fever.

- hSBA Geometric Mean Titers (GMTs) Against N. Meningitidis Serogroups A, C, W, and Y After Receiving One Dose of Either MenACWY-CRM Vaccine or MenACWY-TT Vaccine.(Day 1, Day 29 and Day 180 post-vaccination)
- Percentages of Subjects With rSBA Titer ≥ 128 Against Serogroups A, C, W, and Y After Receiving One Dose of Either MenACWY-CRM Vaccine or MenACWY-TT Vaccine.(Day 1, Day 29 and Day 180 post-vaccination)
- rSBA GMT Against N. Meningitidis Against Serogroups A, C, W, and Y After Receiving One Dose of Either MenACWY-CRM Vaccine or MenACWY-TT Vaccine.(Day 1, Day 29 and Day 180 post-vaccination)
- Percentages of Subjects With Seroresponse Against N. Meningitidis Serogroups A, C, W, and Y After Receiving One Dose of Either MenACWY-CRM Vaccine or MenACWY-TT Vaccine.(Day 29 and Day 180 post-vaccination)

- Percentages of Subjects With Four-fold Increase in rSBA Titers Against Serogroups A, C, W, and Y After Receiving One Dose of Either MenACWY-CRM Vaccine or MenACWY-TT Vaccine.(Day 29 and Day 180 post-vaccination)
