Avian Influenza: Disease Control

The use of avian influenza vaccination in kept and wild birds is controlled by legislation. Defra’s and Welsh Government’s policy on vaccination is set out in the Notifiable Avian Disease Control Strategy for Great Britain and Defra’s Avian influenza (bird flu) vaccination guidance. The cross Government and industry avian influenza vaccination task force develops recommendations for the use of vaccination to prevent the spread of avian influenza in the UK. Defra and Welsh Government have no plans to vaccinate the wild bird population against avian influenza.

In England, the vaccination of birds against avian influenza, except those kept in licensed zoos in England subject to authorisation by the Animal and Plant Health Agency, is not currently permitted. High standards of biosecurity, separation of poultry and other captive birds from wild birds, and careful surveillance for signs of disease remain the most effective means of controlling avian influenza.

In practice, existing vaccines can only be administered via injection. This precludes widespread use in wild birds. While vaccination can reduce mortality, it is likely that some vaccinated birds would still be capable of transmitting avian influenza if they became infected.
