Two avian influenza vaccines have proven to be effective against the disease in chickens, as demonstrated in the initial findings of a field trial conducted at Dutch poultry farms. The vaccinated day-old chicks showed no symptoms of the disease after 8 weeks, indicating a positive outcome in preventing avian influenza. In addition, the absence of virus excretion and the development of an immune response against the virus were notable results observed in the vaccinated group.
While the first 2 vaccines have shown promising results, the Dutch government is considering introducing a third vaccine into the pilot program. This new vaccine, expected to receive European approval shortly, offers a potential alternative in the fight against avian influenza. Dutch agricultural minister Pieter Adema highlights the importance of European approval for the successful continuation of the pilot study, emphasizing the need for effective preventive measures.
Over the next 18 months, additional transmission tests will be conducted to evaluate the effectiveness of the vaccines throughout the laying cycle. Collaborative efforts from Wageningen UR, Royal GD, Utrecht University, and Avined are driving the research forward, building on the success of previous laboratory studies.
The Netherlands' strategic approach to combating avian influenza involves a pilot study at layer farms, set to commence after the summer season. This initiative aims to provide practical insights into vaccination implementation under real-world conditions. Additionally, a robust surveillance program will be established to swiftly detect any potential contamination post-vaccination.
Efforts are underway to address trade barriers for products from vaccinated animals, with discussions ongoing with international stakeholders. The pilot study results are anticipated in the first half of 2025, with potential implications for large-scale vaccination strategies in the poultry sector.
