Outcome

Type Measure Description Time frame Safety issue
Primary Number of Subjects With at Least One Severe Solicited Adverse Event (AE) After Receiving One Dose of Either MenACWY-CRM Vaccine or MenACWY-TT. 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. Day 1 to Day 7 post-vaccination
Secondary Percentages of Subjects With Human Serum Bactericidal Assay (hSBA) Titer = 8 Against (N. Meningitidis) Serogroups A, C, W, and Y After Receiving One Dose of Either MenACWY-CRM Vaccine or MenACWY-TT Vaccine. Immunogenicity of one dose of MenACWY-CRM and comparator MenACWY-TT vaccine was assessed in subjects (12 to 15 months old) as measured by the percentages of subjects with hSBA titer = 8 directed against Neisseria meningitidis (N. meningitidis) serogroups A, C, W, and Y on Day 29 after vaccination. Persistence of immune responses was measured by the percentages of subjects with hSBA titer = 8 on Day 180 post-vaccination. Day 1, Day 29 and Day 180 post-vaccination
Secondary 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. Immunogenicity of one dose of MenACWY-CRM and comparator MenACWY-TT vaccine was assessed in subjects (12 to 15 months old) as measured by the percentages of subjects with seroresponse defined as for subjects with pre-vaccination hSBA titer < 4, post-vaccination hSBA titer = 8; for subjects with pre-vaccination hSBA titer = 4, an increase of at least four times the pre-vaccination hSBA directed against N. meningitidis serogroups A, C, W, and Y on Day 29 after vaccination. Persistence immune response was measured by the percentage of subjects with seroresponse at Day 180 after vaccination. Day 29 and Day 180 post-vaccination
Secondary 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. Immunogenicity of one dose of MenACWY-CRM and comparator MenACWY-TT vaccine was assessed in subjects (12 to 15 months old) as measured by hSBA GMTs directed against N. meningitidis serogroups A, C, W, and Y on Day 29 after vaccination. Persistence of immune response was measured by hSBA GMTs at Day 180 after vaccination. Day 1, Day 29 and Day 180 post-vaccination
Secondary Percentages of Subjects With Rabbit Serum Bactericidal Assay (rSBA) Titer = 8 Against Serogroups A, C, W, and Y After Receiving One Dose of Either MenACWY-CRM Vaccine or MenACWY-TT Vaccine. Immunogenicity of one dose of MenACWY-CRM and comparator MenACWY-TT vaccine was assessed in subjects (12 to 15 months old) as measured by the percentages of subjects with rSBA titer = 8 directed against N. meningitidis serogroups A, C, W, and Y on Day 29 after vaccination. Persistence of immune response was measured by percentages of subjects with rSBA titer = 8 on Day 180 after vaccination. Day 1, Day 29 and Day 180 post-vaccination
Secondary 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. Immunogenicity of one dose of MenACWY-CRM and comparator MenACWY-TT vaccine was assessed in subjects (12 to 15 months old) as measured by the percentages of subjects with rSBA titer = 128 directed against N. meningitidis serogroups A, C, W, and Y on Day 29 after vaccination. Persistence of immune response was measured by percentages of subjects with rSBA titer = 128 on Day 180 after vaccination. Day 1, Day 29 and Day 180 post-vaccination
Secondary 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. Immunogenicity of one dose of MenACWY-CRM and comparator MenACWY-TT vaccine was assessed in subjects (12 to 15 months old) as measured by the percentages of subjects with four-fold increase in rSBA titer directed against N. meningitides serogroups A, C, W, and Y on Day 29 after vaccination. Persistence of immune response was measured by the percentages of subjects with four-fold increase in rSBA titer on Day 180 after vaccination. Day 29 and Day 180 post-vaccination
Secondary 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. Immunogenicity of one dose of MenACWY-CRM and comparator MenACWY-TT vaccine was assessed in subjects (12 to 15 months old) as measured by rSBA GMTs directed against N. meningitidis serogroups A, C, W, and Y on Day 29 after vaccination. Persistence of immune responses was measured by rSBA GMTs on Day 180. Day 1, Day 29 and Day 180 post-vaccination
Secondary Number of Subjects Reporting Solicited Adverse Events (AEs) After Receiving One Dose of Either MenACWY-CRM Vaccine or MenACWY-TT Vaccine. Safety was assessed in terms of number of subjects (12 to 15 months old) reporting any and each of solicited local and systemic AEs reported from Day 1 to 7 after vaccination with one dose of either MenACWY-CRM or comparator MenACWY-TT vaccine. Day 1 (6 hours) to Day 7 post-vaccination
Secondary Number of Subjects Reporting Unsolicited (AEs) After Receiving One Dose of Either MenACWY-CRM Vaccine or MenACWY-TT Vaccine. Safety was assessed in terms of number of subjects (12 to 15 months old) reporting unsolicited AEs (day 1 to day 29), SAEs, medically attended AEs, AEs leading to premature study withdrawal (Day 1 to Day 180) after vaccination with one dose of either MenACWY-CRM or comparator MenACWY-TT vaccine. Day 1 to Day 29 or Day 1 to Day 180 post-vaccination
