BACKGROUND: Meningococcal conjugate vaccines were licensed beginning in 2005 on the basis of serologic end points and recommended for use in adolescents. A single dose at age 11 to 12 years was expected to provide protection through late adolescence. We conducted a case-control evaluation of vaccine effectiveness (VE) and duration of protection of a meningococcal (groups A, C, W, and Y) polysaccharide diphtheria toxoid conjugate vaccine (MenACWY-D). METHODS: Cases of culture- or polymerase chain reaction-confirmed serogroup A, C, W, and Y meningococcal disease among adolescents were identified through meningococcal disease surveillance sites in the United States from January 1, 2006, through August 31, 2013...

BACKGROUND: In September, 2015, the UK became the first country to introduce the multicomponent group B meningococcal (MenB) vaccine (4CMenB, Bexsero) into a publicly funded national immunisation programme. A reduced two-dose priming schedule was offered to infants at 2 months and 4 months, alongside an opportunistic catch-up for 3 month and 4 month olds. 4CMenB was predicted to protect against 73-88% of MenB strains. We aimed to assess the effectiveness and impact of 4CMenB in vaccine-eligible infants in England...

A new MenACWY conjugate meningococcal vaccination programme was introduced in Northern Ireland (NI) in August 2015, for 13-18 year olds, as well as for first-time university entrants up to 25 years. This reflected the response made by Public Health England, due to the recent rapid increase of meningococcal group W (MenW) disease and on advice of the UK Joint Committee on Vaccination and Immunisation (JCVI). The aims of this study were to evaluate (i) the uptake of the MenACWY vaccine among first-time university students, (ii) vaccine and meningitis awareness, (iii) optimal communication modalities via a multidisciplinary team (MDT) model and (iv) current international vaccination policies relating to non-UK students...

REVIEW
Beverley C Millar, P J A Moore, J E Moore
Meningococcal disease is a worldwide life-threatening infection associated in many cases with debilitating long-term sequelae, both within the military and civilian populations. Military recruits are at a higher risk of acquiring this infection due to numerous factors, such as young recruits in the age group 18-25 years, high carriage rates of meningococci, communal and crowed living quarters and global deployment or training in regions with different meningococcal serogroup epidemiology. Although these increased risk factors among young recruits remain, the increased incidence of disease is now historic...

The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV- AEP) annually publishes the immunisation schedule which, in our opinion, is considered optimal for children resident in Spain, taking into account the evidence available on current vaccines. Pneumococcal and varicella immunisation in early childhood is already included in all funded vaccines present in the regional immunisation programmes. Furthermore, this committee establishes recommendations on vaccines not included in official calendars (non-funded immunisations), such as rotavirus, meningococcal B, and meningococcal ACWY...

BACKGROUND: Use of a polysaccharide vaccine challenge to demonstrate immunologic memory after priming with capsular group C meningococcal conjugate vaccines (MenCC) risks induction of immunologic hyporesponsiveness. For this reason, MenCC vaccines are now used as probes of immunologic memory, however, no studies have demonstrated their ability to distinguish primed from unprimed children. METHODS: This study was part of a randomised controlled trial investigating the immunogenicity of a booster dose of the combined Haemophilus influenzae type b and MenC-tetanus toxoid vaccine (Hib-MenC-TT) in infants receiving reduced dose MenCC vaccine priming schedules (one MenC-CRM/MenC-TT or two MenC-CRM vaccine doses) compared with an unprimed group...

BACKGROUND: In Quebec, one dose of monovalent C meningococcal conjugate vaccine (Men-C-Con) is offered at 12 months of age and a booster dose in grade 9 (14-15 years of age). In other Canadian provinces, a quadrivalent ACWY vaccine (Men-4-Con) is increasingly used for adolescents. An economic analysis was performed to assess the value of a switch from Men-C-Con to Men-4-Con. METHODS: A compartmental static simulation model was developed to assess the burden of AWY invasive meningococcal disease (IMD) in a cohort of 100,000 persons with different vaccination programs...

BACKGROUND: Group B Neisseria meningitidis, an endotoxin-producing Gram-negative bacterium, causes the highest incidence of group B meningococcus (MenB) disease in the first year of life. The Bexsero vaccine is indicated in Europe from 8 weeks of age. Endotoxin components of outer membrane vesicles (OMVs) or soluble lipopolysaccharide (LPS) represent a potential source of inflammation and residual reactogenicity. The purpose of this study was to compare novel candidate MenB vaccine formulations with licensed vaccines, including Bexsero, using age-specific human in vitro culture systems...

Neisseria meningitidis serogroup B (MenB) is an important cause of invasive meningococcal disease. The development of safe and effective vaccines with activity across the diversity of MenB strains has been challenging. While capsular polysaccharide conjugate vaccines have been highly successful in the prevention of disease due to meningococcal serogroups A, C, W, and Y, this approach has not been possible for MenB owing to the poor immunogenicity of the MenB capsular polysaccharide. Vaccines based on outer membrane vesicles have been successful in the prevention of invasive MenB disease caused by the single epidemic strain from which they were derived, but they do not confer broad protection against diverse MenB strains...

BACKGROUND AND OBJECTIVES: Neisseria meningitidis is transmitted from person-to-person. Thus, close contact with a healthy carrier can facilitate the spread of the bacteria and lead to life-threatening meningococcal disease. The aim of this study was to identify oropharyngeal carriers of N. meningitidis in volunteers preparing for military service before vaccination. MATERIALS AND METHODS: In a cross-sectional study, 226 volunteers entering military service were referred to the Shemiranat Health Center for meningococcal vaccination and assayed...
