Because France is also part of the European Poultry Trading Region (EPTR, excluding Great Britain), the new import rules also apply to duck products from these countries, as well as from Iceland, Switzerland, Liechtenstein, and Norway. The Netherlands is currently conducting field trials with the vaccination of chicks to develop a vaccine for chicks and chickens, but has not yet made a decision on vaccinating all poultry.
The United States itself is also struggling with avian influenza and has already imposed restrictions on all countries where the disease occurs. Until relatively recently β except for China, Indonesia, Egypt, Vietnam, and Hong Kong β most countries have so far refrained from vaccination in favor of the international recommendation to control HPAI infections by culling infected flocks.
