The purpose of this investigation was to determine the proportion of influenza-like illness (ILI) attributable to specific viruses during the influenza A(H1N1)2009 pandemic and to describe the demographic and clinical characteristics of ILI due to respiratory viruses in Belgium. Nasopharyngeal swabs were collected from ILI patients by general practitioners(More)
The 2014-2015 influenza season in Belgium was dominated by the circulation of 2 influenza A(H3N2) subgroups: 3C.2a and 3C.3b. Analysis of 166 nasopharyngeal aspirates, collected in patients with respiratory illness at the start of the epidemic season, showed a decreased sensitivity for the detection of influenza A(H3N2)/3C.2a using a commercially available(More)
BACKGROUND AND OBJECTIVES In 2009, the pandemic influenza A/H1N1 accounted for worldwide recommendations about vaccination. There are few data concerning the immunogenicity or the security of the adjuvanted-A/H1N1 vaccine in transplanted and hemodialyzed patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Sera from 21 controls, 53 hemodialyzed (HD)(More)
BACKGROUND The 2009 pandemic of influenza A (H1N1) prompted an urgent worldwide vaccination campaign, especially of high-risk subjects, such as maintenance haemodialysis (HD) patients. Still the immunogenicity of the pandemic A (H1N1) vaccine in HD patients is unknown. METHODS We prospectively studied the immunogenicity of a monovalent adjuvanted(More)
Follicular regulatory T cells (TFR) have been extensively characterized in mice and participate in germinal center responses by regulating the maturation of B cells and production of (auto)antibodies. We report that circulating TFR are phenotypically distinct from tonsil-derived TFR in humans. They have a lower expression of follicular markers, and display(More)
BACKGROUND Countries in the World Health Organization (WHO) European Region are reporting more severe influenza activity in the 2015-2016 season compared to previous seasons. OBJECTIVES To conduct a rapid risk assessment to provide interim information on the severity of the current influenza season METHODS: Using the WHO manual for rapid risk assessment(More)
