There is provision in the Diseases of Poultry (
) Order 2003 for the imposition of a compulsory vaccination zone. However, in view of the limitations, summarised below, vaccination is not expected to be part of the current GB avian influenza control strategy. England
- The vaccines that are currently available to protect against AI disease are inactivated types and need to be delivered by injecting birds individually. It can take up to three weeks for birds to develop optimum protective immunity and some poultry require two doses. Delivering such a vaccine, as an emergency measure, to large numbers of birds can raise significant logistical difficulties
- These vaccines protect against disease but will not protect birds from becoming infected and shedding virus. Although vaccination will reduce the amount of virus shed by birds and hence the viral load, this reduced amount may be still be significant and could cause infection in other birds
- Although there are strategies to differentiate vaccinated birds from infected birds, such as the use of DIVA strategies and unvaccinated sentinel birds, vaccination may lead to difficulties in identifying birds that are carrying the virus; this can be a problem for control
- No AI vaccines have marketing authorisation in

I read today the article below printed on www.warmwell.com
Please can you tell me how those if us who keep poultry can have our flocks vaccinated.
Do we contact our own vets for this?
