Of all measles cases reported across the one-year period 1 September 2016 - 31 August 2017 with known vaccination status, 87% were not vaccinated. Measles increasingly affects all age groups across Europe. In 2016, 25.5% of measles cases were above 20 years of age; in 2017, this percentage increased to 47%. The three countries mostly affected by measles over 2016 and the first half of 2017 show different trends: Romania saw a sharp increase in cases from October 2016, and the trend continues in 2017; in Italy, the increasing trend started in January 2017, while in Germany it began in February 2017. This data is based on analysis of the cases notified to ECDC and included in the monthly and biannual monitoring reports.

The latest available figures on vaccination coverage collected by WHO (2016) show that the vaccination coverage for the first dose of measles was below 95% in 18 of 30 EU/EEA countries; for the second dose of measles, it was below 95% in 20 of 27 EU/EEA countries reporting second dose coverage data.

In order to achieve the measles elimination goal, the vaccination coverage rates for children targeted by routine vaccination programmes should increase in a number of countries, as the vaccination coverage of the second dose must be at least 95% to interrupt measles circulation and achieve herd immunity. This is particularly important to protect children below one year of age, who are particularly vulnerable to complications of measles but are too young to have received the first dose of vaccine.

ECDC collects measles data on a monthly basis via The European Surveillance System (TESSy). In addition, ECDC monitors measles and rubella epidemiology and outbreaks via epidemic intelligence.
