Filter by:This is an observational cross sectional study to evaluate the impact of a 4CMenB vaccination program on oropharyngeal N. meningitidis carriage in vaccinated and unvaccinated school leavers.
This study will be an open label, exploratory immunogenicity study conducted by the Oxford Vaccine Group, University of Oxford. This study will investigate the breadth of protective activity of serum anti-FHbp antibody responses of adults immunized with 4CMenB (Bexsero®) vaccine as well as investigating the nature of the B-cell and T-cell responses induced by vaccination. The investigators aim to enroll 15 to 20 healthy adults aged 18 to 60, who will be immunized with two doses of 4CMenB (Bexsero®) two months apart according to the licensed schedule. Blood samples will be obtained at baseline and after each dose of vaccine.
The purpose of this study is to evaluate the safety, reactogenicity and immunogenicity of GSK Biologicals' Hib-MenCY-TT (MenHibrix®) vaccine co-administered with Rotarix, Prevnar 13 and Havrix as compared to PedvaxHIB co-administered with Rotarix, Prevnar 13 and Havrix in infants and toddlers.
To evaluate the immune response and the safety of a primary series schedule that includes V419 (PR5I) at 2 and 6 months of age and Pediacel at 4 months of age Primary objectives - To demonstrate that the mixed schedule induces acceptable responses for Hepatitis B (HB) one month after completion of the mixed schedule - To demonstrate that the mixed schedule induces acceptable responses for Haemophilus influenzae type b (Hib) one month after completion of the mixed schedule Secondary objectives - To describe the antibody response to all PR5I antigens one month after completion of the mixed schedule - To describe the antibody response to meningococcal serogroup C (MCC) conjugate vaccine one month after the second dose of MenC vaccine - To describe the safety profile after each dose of study vaccines administered
Primary Series Primary objectives - To demonstrate that the concomitant administration of the hexavalent vaccine with a meningococcal serogroup C conjugate vaccine is non inferior to the administration of the hexavalent vaccine without a MenC vaccine concomitantly in term of seroprotection rate for hepatitis B one month after the third dose of the hexavalent vaccine - To demonstrate that the concomitant administration of a MenC vaccine with the hexavalent vaccine induces an acceptable response for MenC in term of seroprotection rate (SPR) one month after the second dose of MenC Booster Primary objectives - To describe the immunogenicity of a booster dose of the hexavalent vaccine and of a meningococcal group ACWY conjugate (MenACWY) vaccine either co-administered at 12 months of age or given separately.
This study aims to provide an estimate of the proportion of suspected cases of bacterial meningitis that are due to N. meningitidis and the serogroup responsible in The Philippines and Vietnam.
The main objective of the study is to estimate the proportion of children, born between the 06/04/2004 and the 17/004/2008, living around Neufchatel en Bray, vaccinated by MenBVac, with a serum bactericidal activity against B:14,P1-7,16 clone related to a protection (>= 4), before the fourth dose of MenBvac and after: 6 weeks and one year after the fourth dose.
The primary objectives of this study are to evaluate the immunogenicity and safety of concomitant administration of V419 (PR51) with 2 types of meningococcal serogroup C conjugate (MCC) vaccines to healthy infants at 3 and 4 months of age in terms of antibody seroprotection rate (SPR) to MCC. Participants also received a Haemophilus influenza type B (Hib)-MCC vaccination at 12 months of age. It was hypothesized that the SPR to MCC at 1 month post-dose 2 of either tetanus toxoid conjugated Meningo C (MCC-TT) or CRM197 conjugated Meningo C (MCC-CRM) vaccines would be acceptable when administered concomitantly with V419.
The purpose of this study is to assess the feasibility of a single priming dose of NeisVac-C in infants (at either 4 or 6 months of age), as determined by immune response.
This study will evaluate the safety and immunogenicity of GSK Biologicals' GSK2202083 vaccine co-administered with Prevenar 13® at 2, 4 and 12 months of age and with Rotarix™ at 2 and 4 months of age.
