Filter by:The main objective is to determine whether immune responses to Tdap (GlaxoSmithKline, Boostrix®) and HPV vaccine (Merck & Co., Inc., Gardasil®) when administered concomitantly with MenACWY are comparable to responses elicited by these vaccines when given alone.
The primary objective of this study is to demonstrate the equivalence of rMenB+OMV NZ lot 1 to rMenB+OMV NZ lot 2 when administered to adolescents, as measured by human serum bactericidal activity (hSBA) geometric mean titers (GMTs) against 3 N. meningitidis serogroup B reference strains (H44/76, 5/99, and NZ98/254) and as measured by ELISA geometric mean concentrations (GMCs) against vaccine antigen 287-953, approximately 30 days after a primary vaccination course of two doses administered one month apart.
This study will evaluate safety, tolerability, and immunogenicity of a booster dose of a meningococcal vaccine formulation in adolescents.
A multicenter phase 3 safety trial in which 5,700 subjects will be assigned in a 2:1 ratio to receive 120 μg rLP2086 vaccine in a 0, 2, 6 month schedule or control. The control group will receive HAVRIX vaccine at month 0 and 6 and saline at month 2. All subjects will be followed for 6 months after the last vaccination to assess safety and tolerability.
The proposed study is aimed at assessing the safety and immunogenicity of rMenB+OMV NZ when administered alone without routine infant vaccines to healthy infants in their first year of life according to different two and three dose immunization schedules, which are suitable to be adopted by various national programs. This study will also investigate antibody persistence post primary series and administration of a subsequent booster dose of rMenB+OMV NZ at 11 months of age. In addition, this study will assess the safety and immunogenicity of two catch-up doses of rMenB+OMV NZ when administered to healthy children 2 to 10 years of age. This study will also evaluate the safety and immunogenicity of the concomitant administration of rMenB+OMV NZ with meningococcal C conjugate vaccine (MenC-CRM) according to a 3, 5 and 12-month schedule.
This study is designed to evaluate the immunogenicity and the safety of a quadrivalent vaccine MenACWY-CRM in healthy subjects from 11 to 55 years of age in Korea.
The purpose of this trial is to describe antibody persistence and response to re-vaccination with either Menactra® or Menomune® vaccine approximately three years following initial vaccination in adults who participated in trial MTA29 (NCT00874549). Objectives: - To describe the rates of immediate reactions, solicited injection-site and systemic reactions, all unsolicited adverse events, and serious adverse events following vaccination. - To evaluate persistence of serum bactericidal antibodies in subjects who received Menactra® or Menomune® vaccine approximately three years ago. - To evaluate the immune response to serogroups A, C, Y, and W-135 in subjects re-vaccinated with either Menactra® or Menomune® vaccine.
The purpose of this study was to assess immunogenicity of a 3-dose versus 4-dose infant vaccination schedule including kinetics of immune response in the early phases of the series.
The purpose of this phase 2 study is to evaluate the safety, tolerability and immunogenicity of two doses of 4 different investigational MenABCWY combination vaccine when administered to healthy adolescents aged 11-18 years.
There is evidence of waning immunity in individuals vaccinated against meningitis C as part of the UK infant immunisation schedule. The intention of this study is to contact participants of a previous NVEC (National Vaccine Evalutaion Consortium) clinical trial (a PreSchool Men C trial, in which participants were randomised to receive Meningitec, Menjugate or Neisvac-C). They will be invited to enrol and will be randomised to receive one of two quadrivalent meningococcal ACWY vaccines, to look at the boosting effect they may confer.
