Filter by:The scientific name of meningococcus is Neisseria meningitidis (Nm), the causative agent of epidemic meningococcal meningitis (rheumatoid encephalitis), which colonizes the mucous membranes of the human nasopharynx or causes local infection and can cross the mucosal barrier to cause invasive bacteremia or epidemic meningococcal meningitis, meningococcus can often cause serious disease epidemics worldwide, the main clinical features of its infection are fever, rash and meningitis, the most common clinical manifestation is acute bacterial meningitis.
The purpose of this study is to evaluate the immunogenicity and safety of Meningococcal ACYW135 Polysaccharide Conjugate Vaccine in healthy volunteers aged from 3 to 5 months.
The purpose of this study is to assess the safety, tolerability, and immunogenicity of the combined meningococcal groups A, B, C, W and Y (MenABCWY) vaccine (GSK3536819A) intended to protect against invasive meningococcal disease (IMD) caused by all 5 meningococcal serogroups.
This is a pilot study to assess the feasibility of establishing a national sero-epidemiological survey in England in individuals aged 0-24 years, focusing on assessing humoral immunity against diphtheria, Group C invasive meningococcus and SARS-CoV-2. The investigators will recruit 2800 to 3800 individuals, divided into three groups: Group one (N= 2300): This will include all age groups (0-24years), with recruitment restricted by postcodes provided by Public Health England (PHE) to recruit a representative population for the region as assessed by the IMD (Index of Multiple Deprivation scores). Group two (N= up to 1200): This group has been added following additional funding to enhance the sample size in response to the COVID-19 pandemic. This will recruit 0-19 year olds and will not be restricted by post code sampling. Instead recruitment will be by public promotion within the normal recruiting regions for each site. Group three (N= up to 300): Addition of Group 3 which is enhanced surveillance in participants from Black, Asian or minority ethnic groups (BAME). Since the start of recruitment we have noted that only 11% of participants are from BAME population, despite recruiting in ethnically diverse regions. Given the increased risk of COVID-19 disease in the BAME community, this is a potential limitation of the study as it stands, not only because it may not reflect the diversity of the UK population, but because it does not allow assessment of whether the differing disease rates and seropositivity in adults are reflected in differences in seropositivity rates in children. Similarly to Group 2, this will recruit 0-19 year olds and will not be restricted by post code sampling.
The purpose of this study is to determine when a memory immune response after re-vaccination with Meningococcal C conjugate vaccine (Menjugate) or challenge with Meningococcal A/C polysaccharide vaccine can be observed, after initial vaccination with Meningococcal C conjugate vaccine during the UK immunization campaign
