Subjects were previously vaccinated at 11 to 17 years of age. This extension phase starts 24 months after vaccination and the subjects who were vaccinated in the primary study will be enrolled in this extension phase. No new subjects will be enrolled.
Subjects were previously vaccinated at 11 to 17 months of age with GSK Biologicals' meningococcal vaccine 134612 or with Mencevax™. This extension phase starts 24 months after vaccination and the subjects who were vaccinated in the primary study will be enrolled in this extension phase. No new studies will be enrolled. The subjects will have 4 blood samples taken: at 24, 36, 48 and 60 months after vaccination.

Invasive meningococcal disease and meningococcal meningitis caused by Neisseria meningitidis have their highest incidence in children, with a second peak in adolescents and young adults. T...
The purpose of this study is to evaluate how well the immuno response against meningococcal serogroups A, C, W and Y lasts in children who were vaccinated with MenACWY as infants.
The primary objective of the study is to demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C, W, and Y when MenACYW conjugate vaccine is administered...
The purpose of the study is to evaluate the quadrivalent meningococcal conjugate vaccine when used as a single-dose toddler vaccine in individuals who are either meningococcal vaccine naï...
The purpose of the study is to demonstrate the immune lot consistency of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of ...
Safety and immunogenicity of a pentavalent meningococcal conjugate vaccine containing serogroups A, C, Y, W, and X in healthy adults: a phase 1, single-centre, double-blind, randomised, controlled study.
Invasive meningococcal disease is an important public health problem, especially in sub-Saharan Africa. After introduction of MenAfriVac in 2010, Neisseria meningitidis serogroup A disease has been al...
The Hajj and Umrah mass gatherings represent many of the risk factors for meningococcal disease and have historically been associated with both local and international outbreaks of the disease. The im...
Invasive meningococcal disease has its highest incidence in infants. Co-administration of serogroup B (4CMenB) and quadrivalent conjugate (MenACWY-CRM) vaccines could protect against 5 clinically-rele...
Meningococcal disease is a rare, but serious, bacterial infection that progresses rapidly and can be life-threatening, even with prompt antibiotic treatment. Men who have sex with men (MSM) have previ...
In sub Saharan Africa, the epidemiology, including the distribution of serogroups of strains of N. meningitidis is poorly investigated in countries outside "the meningitis belt". This study was conduc...
Sampling of blood levels of the adrenocorticotropic hormone (ACTH) by withdrawal of blood from the inferior petrosal sinus. The inferior petrosal sinus arises from the cavernous sinus and runs to the internal jugular vein. Sampling of blood at this level is a valuable tool in the differential diagnosis of Cushing disease, Cushing syndrome, and other adrenocortical diseases.
A species of gram-negative, aerobic BACTERIA. It is a commensal and pathogen only of humans, and can be carried asymptomatically in the NASOPHARYNX. When found in cerebrospinal fluid it is the causative agent of cerebrospinal meningitis (MENINGITIS, MENINGOCOCCAL). It is also found in venereal discharges and blood. There are at least 13 serogroups based on antigenic differences in the capsular polysaccharides; the ones causing most meningitis infections being A, B, C, Y, and W-135. Each serogroup can be further classified by serotype, serosubtype, and immunotype.
A sampling methodology using small sample sizes when conducting surveys in small geographical or population-based areas or lots.
A method for diagnosis of fetal diseases by sampling the cells of the placental chorionic villi for DNA analysis, presence of bacteria, concentration of metabolites, etc. The advantage over amniocentesis is that the procedure can be carried out in the first trimester.
A fulminant infection of the meninges and subarachnoid fluid by the bacterium NEISSERIA MENINGITIDIS, producing diffuse inflammation and peri-meningeal venous thromboses. Clinical manifestations include FEVER, nuchal rigidity, SEIZURES, severe HEADACHE, petechial rash, stupor, focal neurologic deficits, HYDROCEPHALUS, and COMA. The organism is usually transmitted via nasopharyngeal secretions and is a leading cause of meningitis in children and young adults. Organisms from Neisseria meningitidis serogroups A, B, C, Y, and W-135 have been reported to cause meningitis.
