Background to the scientific opinion
- The European Union (EU) has experienced an epidemic of highly pathogenic avian influenza (HPAI) in wild and domestic birds in recent years.
- Areas with dense populations of poultry farms are at particular risk of HPAI transmission.
- Vaccination can be considered in addition to already implemented measures (e.g. surveillance, biosecurity and early detections) to prevent and control the spread of HPAI.
What was EFSA asked to do?
- The European Commission requested an overview of the available HPAI vaccines, their efficacy against currently circulating viruses and an assessment of various vaccination schemes to inform decisions on possible vaccination strategies.
- EFSA was also mandated to assess the surveillance and risk mitigation measures in vaccinated areas and farms. These topics will be addressed in a separate scientific opinion, with expected finalisation in March 2024.
