UK Launches First Bird Flu Vaccine Trial for Poultry

The United Kingdom government has initiated its first trial of a vaccine specifically designed for poultry, marking a significant step in the ongoing effort to control avian influenza (bird flu). The trials, which began on Thursday, March 5, 2026, will focus on turkeys in England and aim to assess the efficacy of the latest vaccines in a real-world setting.

Addressing a Growing Threat

Avian influenza outbreaks have been escalating in both the UK and Europe in recent years, causing substantial disruption to the poultry sector and devastating impacts on both wild and captive bird populations. These outbreaks currently cost the UK Government and industry up to £174 million annually [1]. The disease has been a global concern since 2020, impacting bird health worldwide.

Why Turkeys?

Turkeys have been prioritized for this initial research phase due to their high susceptibility to avian influenza. Outbreaks in turkey populations often result in rapid and severe illness, leading to high mortality rates [1]. Understanding how vaccines perform in this vulnerable species is crucial.

Trial Details and Oversight

The trials will involve a small group of birds carefully monitored under strict supervision. The Veterinary Medicines Directorate (VMD) has approved the use of UK/EU authorized vaccines for this purpose [1]. Currently, widespread vaccination of poultry against bird flu is not permitted in the UK.

Looking Ahead

Biosecurity Minister Baroness Hayman emphasized the importance of these trials, stating they represent a “significant step forward” in the fight against the disease and will contribute to global research efforts [3]. The trials will provide valuable insights into vaccine effectiveness, surveillance strategies and maintaining trade continuity. The UK government is hopeful that vaccines can become an additional tool in controlling bird flu, protecting the nation’s biosecurity and food supply [3].

Human Health Considerations

Alongside animal health, the UK Health Security Agency (UKHSA) provides guidance on managing the human health risks associated with avian influenza incidents in birds [2]. Strict and standard approaches are in place for responding to suspected and confirmed cases.
