Post-licensure Safety Surveillance Study of Menactra Vaccine When Administered As a 2-dose Schedule...

MeningitisMeningococcal Infection

This is a passive-surveillance study that will accrue subjects for surveillance. For each accrued subject, surveillance for outcomes will continue for six months following the first dose. If a second dose is given within that time, then surveillance will be continued for six months following the second dose. Observational Objective: To describe and characterize adverse events occurring after vaccination with Menactra vaccine.

MeningitisMeningococcal Meningitis1 more

To evaluate Immunogenicity and Safety of Adjuvant and Adjuvant-Free Meningococcal Groups A and C and Haemophilus b Conjugate Vaccine in Infants 2 to 5 Months of Age. Primary objective: To demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C and Haemophilus influenzae type b following the administration of adjuvant-free MenAC-Hib conjugate vaccine compared to those observed following the administration of adjuvant MenAC-Hib conjugate vaccine. To describe the safety profile of adjuvant-free MenAC-Hib conjugate vaccine compared to that of adjuvant MenAC-Hib conjugate vaccine. Secondary objective: •To compare the antibody level of meningococcal serogroups A, C and Haemophilus influenzae type b following the administration of adjuvant-free MenAC-Hib conjugate vaccine to those observed following the administration of adjuvant MenAC-Hib conjugate vaccine.

Safety Surveillance of MenACWY-CRM Vaccine in Children

Meningococcal Disease

The purpose of this study is to summarize the occurrence of incident serious medically attended events and events of interest up to 1 year following MenACWY-CRM vaccination administered as part of routine clinical care. This US FDA post-marketing commitment study is an open-label, descriptive, epidemiological safety surveillance study of MenACWY-CRM vaccine in subjects 2 to 10 years of age within a large US Healthcare Maintenance Organization. The 26 events of interest are events commonly evaluated in vaccine safety studies and include certain neurological, immunological, vascular, musculoskeletal and hematologic disorders. All events are collected retrospectively.

MenPF-1 - A New Vaccine Against Meningococcal Disease

Serogroup B Meningococcal Disease

In this study the investigators are testing a new vaccine against Neisseria meningitidis, the leading infective cause of childhood death in the UK. This bug (also known as meningococcus) can infect the lining of the brain (meningitis) or the blood stream (septicaemia) and can affect all ages, but especially children, adolescents and young adults. The bug is classified into different groups based on its outer capsule (or shell), and this study will test a new vaccine to protect against group B meningococcus (MenB) disease, which is the most common type in the UK. Vaccines are given to prepare the immune system to fight an infection. Vaccines work by stimulating the immune system to produce specialised proteins (called antibodies) and white blood cells designed to kill the bug later in life if needed. Vaccines against other types of meningococcus have been developed and saved many lives. However MenB is different because its outer capsule does not stimulate the immune system very effectively. There is therefore no broadly effective vaccine against MenB disease.

A Case-control Study of the Efficacy of a New Serogroup A Meningococcal Conjugate Vaccine (MenAfriVac)...

Meningococcal Disease

Major epidemics of meningococcal meningitis occur in countries of the African Sahel and sub-Sahel every few years. Most of these epidemics are caused by meningococci belonging to serogroup A. Until recently there has been no serogroup A conjugate vaccine available to prevent epidemics in Africa because none of the major pharmaceutical companies wanted to develop such a vaccine for commercial reasons. For this reason a public private partnership was established in 2001, the Meningitis Vaccine Project (MVP), with support from the Bill and Melinda Gates Foundation, to develop an affordable new serogroup A meningococcal conjugate vaccine for Africa. The new vaccine, MenAfriVac™, received WHO pre-qualification in 2010 and mass campaigns started in Burkina Faso, Mali and Niger in 2010. It is expected that full coverage through mass vaccination campaigns will be achieved by the end of 2011 in these three countries. A case-control study will be conducted in Mali and Niger during the epidemic seasons of 2012 and 2013 to assess the efficacy of MenAfriVac™.
