EU-IBIS, a surveillance network for invasive meningococcal disease, continues to fulfil its aims to gather and improve epidemiological information about the disease, to integrate and analyse molecular data, and to form the focus for a wider collaboration.
Findings in this study confirmed the herd immunity effect of immunizing young children, since invasive meningococcal disease was not only reduced among vaccinees, but in all age groups.
4CMenB has the potential to reduce serogroup B meningococcal disease substantially. Despite its potential, the vaccine may have some limitations, and it remains to be seen if booster doses will be required to sustain protection.
Universal screening of pregnant women is feasible and has led to immunisation in nearly all identified cases in Denmark. As a consequence of the study the National Board of Health has made universal HBsAg screening of pregnant women permanent in the country.
The authors retrospectively analyzed hepatitis A virus (HAV) seroprevalence in travellers who had been born and lived at least 1 year in a developing country, wanted to travel to a hepatitis A endemic area, and consulted at the vaccination centre of the Institut Pasteur of Paris between September 1, 2008 and February 28, 2010. HAV seroprevalence was 82.4 % for a population of 646 immigrants for whom data were available
