Vaccine Effectiveness, Burden and Impact Studies (VEBIS) of COVID-19 and Influenza

Project description

The objectives of the project is to provide technical support to the European Center for Disease Prevention and Control to build an infrastructure to allow regular monitoring of COVID-19 and influenza vaccine effectiveness over time, using a multi-country approach. The VEBIS platform includes vaccine effectiveness studies implemented in different settings.

Context situation

Vaccination plays a key role in the control of the coronavirus disease (COVID-19) pandemic and the lifting of some non-pharmaceutical interventions. Assessment of the real-world performance of the vaccines in the European Union is important to be able to adapt to European vaccination strategies.
