Poultry vaccines
Disease prevention by vaccination is an integral part of flock health management protocols. Active immunization using live vaccines is the current industry standard. Routinely used vaccines in chickens include MDV, NDV, IBV, and IBDV, and in turkeys NDV and HEV. Newer vaccines, including molecular recombinants in which genes of immunogenic proteins from infectious agents are inserted into a live viral vector, are also being examined for commercial use. Efforts are under way to enhance vaccine efficacy by the use of adjuvants, particularly cytokines. The vaccine delivery systems include in ovo injection, aerosol, spray, drinking water, eye drop, and wing web injection. The in ovo vaccination procedure is relatively new and at the present time it is used primarily to vaccinate broiler chickens against MDV. Birds respond to vaccines by developing humoral and cellular immune responses. There are two main types of vaccine available for poultry: live or killed.
The French Ministry of Agriculture announced the intention to vaccinate outdoor ducks against Avian Influenza in three western parts of France (Landes, Loire atlantique and Vendée).
The French Ministry sees these regions at risk for transmission of the influenza virus by migrating birds. The Ministry has requested approval from the European Commission for these plans. Intervet will supply at least 30 million doses, a substantial part of the vaccine tender called by the French Ministry of...

Egg producers now have access to a new tool developed by the Agricultural Research Service that helps protect laying flocks from serious diseases like infectious bronchitis, mycoplasmosis and exotic Newcastle disease. Each year, mycoplasmosis alone costs U.S. producers more than $140 million, partly due to uneven vaccine delivery.
Vaccines are currently dispensed to egg-laying leghorn chickens as an inhalable mist sprayed inside poultry houses. The applicator consists of a hose attached to...

The government yesterday opted for a compromise by approving the limited use of bird flu vaccine, while rejecting a mass cull of ducks.
Vaccines would only be used to immunise fighting cocks, domestic poultry, expensive birds and free-range ducks, while chickens and ducks raised for export would not be vaccinated.
Approval came during a three-hour meeting of the anti-bird flu committee chaired by Prime Minister Thaksin Shinawatra, who last week put the talks on hold for a week to give him...
