External quality assurance scheme for Neisseria meningitidis 2009
Neisseria meningitidis is the major worldwide cause of meningitis and rapidly fatal sepsis in healthy individuals. ECDC promotes the performance of External Quality Assurance (EQA) schemes, in which laboratories are sent simulated clinical specimens or bacterial isolates for testing by routine and/or reference laboratory methods. In March 2009, a collection of six viable isolates of N. meningitidis of the major disease-causing serogroups (A, B, C, Y and W-135) together with six simulated blood (non-culture) samples for molecular studies, was sent to 27 reference laboratories in the EU for quality assurance testing. The laboratories were asked to perform phenotypic characterisation of viable isolates: serogroup, serotype, serosubtype and antimicrobial susceptibility testing on viable isolates, and molecular characterisation both of viable isolates and non-culture simulated septicaemia samples. This report presents the results of this exercise.
Partial COVID-19 vaccination, vaccination following SARS-CoV-2 infection and heterologous vaccination schedule: summary of evidence
22 Jul 2021 - This document provides a review of evidence on three topics of interest (effectiveness of partial vaccination, immunogenicity and effectiveness of vaccination for previously infected individuals and safety and immunogenicity of heterologous schedules) to inform ongoing decision-making in relation to national vaccination policies and strategies in the European Union and European Economic Area (EU/EEA) countries.
COVID-19 in children and the role of school settings in transmission - second update
8 Jul 2021 - The aim of this document is to provide an update on the knowledge surrounding the role of children in the transmission of SARS-CoV-2 and the role of schools in the COVID-19 pandemic, focusing in particular on the experience in EU/EEA countries since the beginning of the pandemic. This document also addresses transmission to and from staff in school settings, school-related mitigation measures including risk communication, testing, contact tracing, and the effectiveness and impacts of school closures.
