Pertussis is an endemic disease in the EU/EEA and worldwide. Every three to five years, larger epidemics are expected even with high vaccination coverage.
On 20 and 24 November 2019, respectively, the Dutch public health authorities confirmed two imported cases of Lassa fever from Sierra Leone. Both were Dutch healthcare workers who worked in a rural hospital in Sierra Leone.
This Rapid Risk Assessment focuses on acellular pertussis-containing combination vaccines used in national vaccination programmes in the EU/EEA Member States.
Early in 2015, a shortage of acellular pertussis-containing vaccines was brought to the attention of ECDC. This risk assessment provides a detailed list of mitigation options available to Member States.
