Abstract
The annual incidence rate of serogroup W invasive meningococcal disease in the Netherlands increased from < 0.05/100,000 (n < 10) before 2015 to 0.5/100,000 (n = 80) in 2017. Most isolates (94%) belong to clonal complex 11. The incidence rate is highest among < 5 year-olds and 15-24 year-olds. The case fatality rate was 12% (17/138) in 2015-2017. From May 2018, MenACWY vaccination replaces MenC vaccination at age 14 months and from October 2018, 13-14 year-olds are offered MenACWY vaccination.
