Filter by:Brief Summary: The main purpose of the study is to learn about how well Trumenba vaccine shot works against gonorrhea infection. This study looks at data records from a database in the United States. This study includes patient's data from the database who: - Are 15-30 years old. - Have received at least one dose of Trumenba and a MenACWY vaccine or who have received only MenACWY vaccine. - Have enough months of data in the database. This data has already been collected in the past and is being studied between April and June of 2023.
Bacterial meningitis is a major cause of morbidity and mortality in childhood. Antibiotic treatment recommendations are based on epidemiological and susceptibility data. The epidemiology of bacterialméningitis has changed in recent years, mainly owing to widespread use of different conjugate vaccines. The aim of this prospective national survey is to describe epidemiology of bacteria implicated in bacterial meningitis in children.
The primary objective of this study is to evaluate the safety of adjuvanted and non-adjuvanted formulations of MCV-5 vaccine. The secondary objective is to assess the immune response of adjuvanted and non-adjuvanted formulations of MCV-5 vaccine.
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.
This is a clinical study to assess the safety, tolerance and immunogenic response to Gardasil (human papilloma virus (HPV)) and rLP2086 vaccine. Healthy male and female subjects will be randomized into 1 of 3 groups; the trial will be an observer-blinded study to the injection being given; and, vaccinated with either Gardasil and rLP2086 concomitantly, rLP2086 and saline concomitantly, or Gardasil and saline concomitantly. The subjects are adolescent children between the ages of 11 and 17 years old.
This is a clinical study to assess the safety, tolerance and immunogenic response to MCV4(quadrivalent meningococcal polysaccharide conjugate, meningococcal serogroups A,C,Y, and W135), Tdap (diphtheria, tetanus, and acellular pertussis), and bivalent rLP2086 vaccine. Healthy male and female subjects, between the ages of 10 to 12 years old, will be randomized into 1 of 3 groups. The subjects, investigators, site staff and sponsor will be blinded to all injections given throughout the study. An unblinded administrator will be responsible to administer the vaccinations to all subjects and will be unblinded to the subject randomization in order to determine which subjects were in randomized to group 3 so they may receive their catch-up vaccinations of MCV4 and Tdap. A final telephone contact will be conducted with all subjects 6-months post their last vaccination to obtain safety information.
The purpose of the study is to evaluate the persistence of the immune response of GSK134612 vaccine up to 68 months after vaccination in the primary vaccination study (NCT number = NCT00674583) of 2 to 10 year old subjects. This study will also evaluate the safety and immunogenicity of a booster dose of GSK134612 vaccine subjects who were primed in the primary vaccination study with either GSK134612 vaccine or Menjugate®. This protocol posting deals with objectives & outcome measures of the persistence and booster epochs. The objectives & outcome measures of the primary epoch are presented in a separate protocol posting (NCT number = NCT00674583)
The purpose of this study is to evaluate immunogenicity and safety of meningococcal conjugate vaccine GSK134612 compared to the licensed vaccines MenC-CRM197 and MenC-TT in infants of 2 months of age. Pneumococcal conjugate vaccine and DTPa-HBV-IPV/Hib vaccines will be co-administered.
The purpose of this study is to demonstrate, in 2-10 year old subjects, the non-inferiority of meningococcal vaccine GSK134612 compared to licensed meningococcal vaccine Mencevax™. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
