E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the immune responses of :
- ProQuad™ vaccine when administered with MenACWY vaccine to that of ProQuad™ vaccine alone to children 12 months of age, as measured by seroconversion rates to measles, mumps, and rubella, and seroprotection rates for varicella.
- two doses of MenACWY given to children at 7 to 9 and 12 months of age, when either administered with ProQuad™ or given alone, as measured by percentage of subjects with serum bactericidal activity (hSBA) ≥1:8 against N. men serogroups A, C, W-135, and Y.
▫ To assess immunogenicity of two doses of MenACWY given to children at 7 to 9 and 12 months of age as measured by the percentage of subjects with hSBA ≥1:8 against N. men serogroups A, C, W-135, and Y. |
|
E.2.2 | Secondary objectives of the trial |
▫ To compare immune responses of 2 doses of MenACWY given to children at 7 to 9 and 12 months of age, when administered with ProQuad™ at 12 months of age or when given alone, as measured by percentage (%)of subjects with hSBA ≥1:4 and hSBA geometric mean titers (GMTs) against N. meningitidis serogroups A, C, W-135, and Y.
▫ To assess immune responses of ProQuad™ when administered with MenACWY or when given alone to children aged 12 months, as measured by GMTs for measles, mumps, rubella and varicella (MMRV).
▫ To assess anti-varicella antibody response when ProQuad™ administered with MenACWY or when given alone to children aged 12 months, as measured by % of subjects who show seroconversion.
▫ To assess immunogenicity of MenACWY after a single dose given at 7 to 9 months of age, as measured by % of subjects with hSBA ≥1:8, hSBA ≥1:4, and hSBA GMTs directed against N. meningitidis serogroups A, C, W-135, and Y.
▫ To describe the safety profile of subjects in each vaccine group. |
