Avian influenza: No one size fits all, says WOAH

Participants discussed the impact of the disease, the fitness for purpose of existing prevention and control tools, the impact on international trade and the need to enhance global coordination.

As expected, vaccination emerged as a critical point of discussion. Countries that previously relied on conventional methods to control avian influenza are now facing overwhelming challenges that have prompted them to explore additional measures. Alongside biosecurity, movement control and stamping out, WOAH’s General Assembly debated vaccination as a complementary tool and extensively discussed its associated implementation challenges.

It was recognised that a successful vaccination strategy must rely on authorised vaccines that closely match the virus strains in circulation and must be matched with robust disease surveillance.

Dr David Swayne, disease expert and forum rapporteur, said: “Vaccinating is not the end; it is just the beginning. Vaccination application needs to be managed along the supply chain, including a surveillance programme to detect active infection in vaccinated animals.”

WOAH members adopted a resolution which will serve as a basis for shaping future avian influenza control activities while protecting wildlife, supporting the poultry sector and the continuity of trade. The Resolution also highlights the importance of countries respecting and implementing WOAH international standards to combat the virus. Recognising the compliant use of vaccination without negative consequences on trade as per WOAH standards further stresses the need for robust vaccination monitoring and disease surveillance systems.
