Vaccination is an important tool in the fight against avian influenza and is recommended as part of an integrated approach to disease control. However, it is necessary to follow a strategic surveillance scheme and put measures in place to reduce the risk of transmission of the virus.

"Maintaining a high level of biosafety remains essential, even when vaccination is used," says Frank Verdonck, head of the Biological Risks and Animal Health and Welfare unit. 'Raising awareness among farm managers and industry operators can help ensure that any changes in poultry production or increased mortality are promptly reported and addressed,' says Verdonk. The European Food Safety Authority (EFSA) has issued a scientific opinion on the issue. The opinion was published this morning and is available on the EFSA website here.
