Yellow fever (YF) is a mosquito-borne viral hemorrhagic fever, which is a serious and potentially fatal disease with no specific antiviral treatment that can be effectively prevented by an attenuated vaccine (YEL). Despite the long history of safe and efficacious YF vaccination, sporadic case reports of serious adverse events (SAEs) have been reported, including yellow fever vaccine-associated neurotropic disease (YEL-AND). YEL-AND usually appears within one month of YF vaccination, manifesting as meningoencephalitis, Guillain-Barré syndrome (GBS) or acute disseminated encephalomyelitis (ADEM)...

Meningococci (Neisseria meningiditis) of serogroups A and W have caused large epidemics of meningitis in sub-Saharan Africa for decades, and affordable and multivalent vaccines, effective in all age groups, are needed. A bivalent serogroup A and W (A + W) meningococcal vaccine candidate consisting of deoxycholate-extracted outer membrane vesicles (OMV) from representative African disease isolates was previously found to be highly immunogenic in outbred mice when formulated with the adjuvant aluminium hydroxide (AH)...

Streptococcus pneumoniae (Sp) strain TIGR4 is a virulent, encapsulated serotype that causes bacteremia, otitis media, meningitis and pneumonia. Increased bacterial resistance and limited efficacy of the available vaccine to some serotypes complicate the treatment of diseases associated to this microorganism. Flavodoxins are bacterial proteins involved in several important metabolic pathways. The Sp flavodoxin (Spfld) gene was recently reported to be essential for the establishment of meningitis in a rat model, which makes SpFld a potential drug target...

STUDY AIM: to assess the incidence, risk factors and outcome of invasive pneumococcal disease (IPD) among the Israeli HIV population. A matched case-control study nested in a nationwide, prospective, population-based, cohort of adult IPD was performed. In addition, the HIV-IPD patients were compared to the general adult HIV population in Israel. STUDY PERIOD: from the introduction of PCV into the national immunization program (NIP) in July 2009 to June 2014. Each HIV patient within the IPD cohort was matched to four non-HIV controls...

: Repeating evaluations of vaccine coverage (VC) is essential to measure the implementation and effectiveness of vaccination policy. We report the results of VC in infants from the Vaccinoscopie(®) study in 2014 to assess the changes secondary to the new 2013 immunization schedule. METHOD: Study conducted on Internet among a representative sample of mothers reporting their child's vaccination record. RESULTS: The removal of the dose of DTPa-Hib at the age of 3 months was quickly adopted since only 1 % of children aged 6 months had received three doses of DTPa in 2014 compared to 96 % in 2012...

Tick-borne encephalitis (TBE) is an arbovirus induced by tick-borne encephalitis virus (TBEV) transmitted by tick bite. The disease is rare in France (two to three cases per year) but endemic zones extend from Western Europe to the east coast of Asia (10,000-15,000 cases per year). An 8-year-old boy was admitted to our pediatric ward in Strasbourg (France) for febrile headache with diplopia. Four days after a tick bite, he declared a febrile headache together with maculopapular rash on the elbows, knees, and cheeks...

BACKGROUND: Ongoing surveillance is critical to assessing pneumococcal conjugate vaccine (PCV) impact over time. However, robust prospective studies are difficult to implement in resource-poor settings. We evaluated retrospective use of routinely collected data to estimate PCV impact in Rwanda. METHODS: We collected data from admission registers at five district hospitals on children age <5yearsadmitted for suspected meningitis and pneumonia during 2002-2012...

Streptococcus pneumoniae is an opportunistic pathogen globally associated with significant morbidity and mortality. It is capable of causing a wide range of diseases including sinusitis, conjunctivitis, otitis media, pneumonia, bacteraemia, sepsis, and meningitis. While its capsular polysaccharide is indispensible for invasive disease, and opsonising antibodies against the capsule are the basis for the current vaccines, a long history of biomedical research indicates that other components of this Gram-positive bacterium are also critical for virulence...

BACKGROUND: Haemophilus influenzae type b (Hib) is the leading cause of bacterial meningitis, otitis media, pneumonia, cellulitis, bacteremia, and septic arthritis in infants and young children. The Hib capsule contains the major virulence factor, and is composed of polyribosyl ribitol phosphate (PRP) that can induce immune system response. Vaccines consisting of Hib capsular polysaccharide (PRP) conjugated to a carrier protein are effective in the prevention of the infections. However, due to costly processes in PRP production, these vaccines are too expensive...

Mumps is a highly contagious viral infection that became rare in most industrialized countries following the introduction of measles-mumps-rubella (MMR) vaccine in 1967. The disease, however, has been re-emerging with several outbreaks over the past decade. Many clinicians have never seen a case of mumps. To assist frontline healthcare providers with detecting potential cases and initiating critical actions, investigators modified the "Identify-Isolate-Inform" tool for mumps infection. The tool is applicable to regions with rare incidences or local outbreaks, especially seen in college students, as well as globally in areas where vaccination is less common...

Streptococcus pneumoniae is one of the causative agent of pneumonia, meningitis, otitis media and sepsis. Vaccination is an effective strategy to combat S.pneumoniae invasion. We previously reported that SPY1, a novel attenuated vaccine candidate against S.pneumoniae, induces a protective immune response against pneumococcal infection in mice. However, underlying mechanisms have yet to be fully illustrated. To explore the mechanism of innate and adaptive immunities induced by SPY1. In this study, bone marrow-derived dendritic cells (DCs) of mice were infected with SPY1 and its parental wild-type strain D39, SPY1-infected DCs were co-cultured with homologous CD4(+)T cells or adoptive transfer to C57BL/6 mice...

Trumenba (bivalent rLP2086) is a vaccine licensed for the prevention of meningococcal meningitis disease caused by Neisseria meningitidis serogroup B (NmB) in individuals 10-25 years of age in the USA. The vaccine is composed of two factor H binding protein (fHbp) variants that were recombinantly expressed in Escherichia coli as native lipoproteins: rLP2086-A05 and rLP2086-B01. The vaccine was shown to induce potent bactericidal antibodies against a broad range of NmB isolates expressing fHbp that were different in sequence from the fHbp vaccine antigens...

Streptococcus iniae causes septicaemia and meningitis in marine and freshwater fish wherever they are farmed in warm-temperate and tropical regions. Although serotype specific, vaccination with bacterins (killed bacterial cultures) is largely successful and vaccine failure occurs only occasionally through emergence of new capsular serotypes. Previously we showed that mutations in vaccine escapes are restricted to a limited repertoire of genes within the 20-gene capsular polysaccharide (cps) operon. cpsG, a putative UDP-galactose 4-epimerase, has three sequence types based on the insertion or deletion of the three amino acids leucine, serine and lysine in the substrate binding site of the protein...
