Immunization is an essential part of care for adults, including pregnant women. Influenza vaccination for pregnant women is especially important because pregnant women who contract influenza are at greater risk of maternal morbidity and mortality in addition to fetal morbidity, including congenital anomalies, spontaneous abortion, preterm birth, and low birth weight. Other vaccines provide maternal protection from severe morbidity related to specific pathogens such as pneumococcus, meningococcus, and hepatitis for at-risk pregnant women...

Objectives: Vaccinations are an important measure to prevent infections in immunocompromised patients. The knowledge of vaccination coverage and reasons for non-vaccination in patients with SLE is scarce. The aim of this study was to assess coverage rates of selected vaccinations in a representative sample of SLE patients and to identify predictors for non-vaccination. Methods: In 2013, information on selected vaccinations (coverage, application and reservations) and on demographics, clinical parameters and health beliefs was assessed by means of a self-reported questionnaire among a representative sample of SLE patients in Germany (LuLa cohort)...

Cell surface carbohydrates have been proven optimal targets for vaccine development. Conjugation of polysaccharides to a carrier protein triggers a T-cell dependent immune response to the glycan moiety. Licensed glycoconjugate vaccines are produced by chemical conjugation of capsular polysaccharides to prevent meningitis caused by meningococcus, pneumococcus and Haemophilus influenzae type b. However, other classes of carbohydrates (O-antigens, exopolysaccharides, wall/teichoic acids) represent attractive targets for developing vaccines...

4CMenB is the first broad coverage vaccine for the prevention of invasive meningococcal disease caused by serogroup B strains. To gain a comprehensive picture of the antibody response induced upon 4CMenB vaccination and to obtain relevant translational information directly from human studies, we have isolated a panel of human monoclonal antibodies from adult vaccinees. Based on the Ig-gene sequence of the variable region, 37 antigen-specific monoclonal antibodies were identified and produced as recombinant Fab fragments, and a subset also produced as full length recombinant IgG1 and functionally characterized...

Sepsis caused by Neisseria meningitidis (meningococcus) is a rapidly progressing, life-threatening disease. Because its initial symptoms are rather unspecific, medical attention is often sought too late, i.e., when the systemic inflammatory response is already unleashed. This in turn limits the success of antibiotic treatment. The complement system is generally accepted as the most important innate immune determinant against invasive meningococcal disease since it protects the host through the bactericidal membrane attack complex...

The introduction of a serogroup A meningococcal conjugate vaccine in the African meningitis belt has been a remarkable success. Meningitis due to the serogroup A meningococcus, previously responsible for most epidemics, has fallen by 99% in vaccinated countries. Success must, however, not distract from the continuing burden of meningitis in this region of Africa. The number of all meningitis epidemics at health district level has fallen by 60% following vaccination, but epidemics due to other meningococcal serogroups continue and may be increasing...

Neisseria meningitidis (meningococcus) can cause meningococcal disease, a rapidly progressing and often fatal disease that can occur in previously healthy children. Meningococci are found in healthy carriers, where they reside in the nasopharynx as commensals. While carriage is relatively common, invasive disease, associated with hypervirulent strains, is a comparatively rare event. The basis of increased virulence in some strains is not well understood. New Zealand suffered a protracted meningococcal disease epidemic, from 1991 to 2008...

Background and aims of the work: Invasive Meningococcal Disease (IMD) represents a global health threat, and occupational settings have the potential to contribute to its spreading. Therefore, here we present the available evidences on the epidemiology of IMD on the workplaces. METHODS: The following key words were used to explore PubMed: Neisseria meningitidis, meningococcus, meningococcal, invasive meningococcal disease, epidemiology, outbreaks, profession(al), occupation(al). RESULTS: We identified a total of 12 IMD cases among healthcare workers (HCW), 44 involving biological laboratory workers (BLW), 8 among school personnel, and eventually 27 from other settings, including 3 large industrial working populations...

Meningococcal group B outer membrane vesicle vaccines have been used widely in Cuba, New Zealand, and Brazil. They are immunogenic and initially assessed largely by their ability to induce serum bactericidal activity. Measures of efficacy indicate good protection against homologous strains in older children and adults. Effectiveness appears broader than predicted by immunogenicity and efficacy studies. The recent discovery that meningococcal group B OMVs may protect against the related Neisseria species N.gonorrhoeae suggests more to these interesting antigen collections than meets the eye...

BACKGROUND: At the time of an infant's initial vaccination at age ∼2 to 3months, some infants already have maternal antibodies against vaccine antigens and these can suppress the immune response to vaccination. Modelling the effects of maternal antibody and the timing of infant doses on the antibody response to vaccination, requires estimates of the rate of maternal antibody decay. Decay rates are not well characterised in the medical literature. We investigated variation in the prevalence of maternal anti-capsular pneumococcal and meningococcal antibodies in infants in 14 countries, and estimated type-specific half-lives...

BACKGROUND: Serum bactericidal antibody titres that correlate with protection against invasive meningococcal disease have been characterised. However, titres that are associated with protection against acquisition of pharyngeal carriage of Neisseria meningitidis are not known. METHODS: Sera were obtained from the members of a household in seven countries of the African meningitis belt in which a pharyngeal carrier of N. meningitidis had been identified during a cross-sectional survey...

PURPOSE OF REVIEW: This review explores the history of serogroup B meningitis outbreaks in American universities and the rise of the monovalent serogroup B meningococcus vaccines (MenB). RECENT FINDINGS: Serogroup B meningitis represents 30% of American meningococcal infections and had no commercially available vaccine in the USA until 2013 when the FDA made an expanded allowance for importation of the MenB-4C vaccine for outbreaks at two American universities. Infections of Neisseria meningitidis, notably meningococcal meningitis represent a continued, lethal threat to the pediatric and adolescent populations and those with primary or acquired complement component deficiencies, largely mitigated by the quadrivalent meningococcal conjugated vaccine against serogroups A, C, W, and Y (MenACWY)...
