UK Launches Turkey Vaccine Trial in Fight Against Bird Flu

In a significant step towards safeguarding the UK poultry sector, a field trial to test highly pathogenic avian influenza (HPAI) vaccines in turkeys has commenced in England. The trial, beginning in March 2026, represents a pivotal moment in the ongoing battle against a disease that has caused substantial disruption to both commercial and backyard flocks.

The Threat of HPAI

Highly pathogenic avian influenza (HPAI) is a growing global concern, with recent outbreaks continuing into the summer months according to the Department for Environment, Food & Rural Affairs. The virus poses a significant threat to poultry health and the wider agricultural economy.

Why Turkeys?

The latest research phase specifically focuses on turkeys, a species particularly susceptible to HPAI. Outbreaks in turkeys have historically resulted in rapid onset of clinical signs and high mortality rates, making producers especially vulnerable. Annual losses attributed to the virus are estimated to reach up to £174 million, impacting both government and industry as reported by Poultry World.

Details of the Trial

The trial will involve a small number of birds kept under strict supervision and vaccinated using approved UK and EU vaccines. Currently, widespread vaccination against bird flu is not permitted in the UK, making this targeted exercise a critical opportunity to assess the potential integration of vaccines into future disease control strategies. The trial is being conducted under strict government oversight and normal husbandry conditions as outlined by the British Poultry Council.

Government and Industry Response

Biosecurity minister Baroness Hayman described the launch as a “significant step forward,” emphasizing the importance of advancing vaccine science given the annual toll of the disease on farmers and the sector. Chief veterinary officer Christine Middlemiss echoed this sentiment, reiterating that stringent biosecurity remains the primary defense against HPAI according to Poultry World.

Looking Ahead

The results of this trial will provide valuable real-world evidence on how vaccination could operate within UK production systems, potentially safeguarding bird health, protecting farm businesses, and strengthening the resilience of the British poultry sector. The UK joint industry, cross-government avian influenza vaccination taskforce established this trial to explore vaccination as a preventative measure against HPAI as detailed in the government publication.

Key Takeaways

• A new field trial is underway to test HPAI vaccines in turkeys in England.
• Turkeys are particularly vulnerable to HPAI, resulting in significant economic losses.
• The trial aims to assess the feasibility of integrating vaccination into future disease control strategies.
• Government and industry are collaborating to address the ongoing threat of HPAI.
