The UK poultry industry is once again wrestling with concerns over avian influenza (bird flu), with farmers calling for the government to permit vaccination as an additional safeguard against the virus. The outbreak of highly pathogenic avian influenza (HPAI) has caused major losses in past years, and although current levels remain below previous peaks, poultry producers are maintaining heightened vigilance. Biosecurity vs. Vaccination – let’s explore the debate.
The current approach: biosecurity and culling
Under existing UK policy, vaccination against bird flu is not allowed for commercial poultry. Instead, the government continues to advocate for stringent biosecurity measures and the culling of infected birds to contain outbreaks. A national Avian Influenza Prevention Zone is in force, requiring strict hygiene standards across poultry operations. In areas deemed high-risk, poultry must be kept indoors to prevent exposure to infected wild birds.
Biosecurity vs. vaccination: industry pressure grows
Many farmers argue that a sole reliance on biosecurity and culling is no longer viable. After experiencing devastating losses in previous outbreaks, they warn that the current system leaves the industry vulnerable. Increasing numbers of producers and industry representatives are urging the government to move more quickly on adopting vaccination as part of a broader disease prevention strategy.
To address these concerns, the government has launched a cross-sector taskforce with the poultry industry to assess the feasibility of introducing vaccination. While a report is anticipated later this year, some stakeholders fear that delaying action could have serious consequences if another major outbreak occurs.
Barriers to poultry vaccination in the UK
Although vaccination could provide a new defence against avian flu, several obstacles must be considered. Trade is a major concern, with some countries imposing restrictions on poultry products from vaccinated birds. Furthermore, any vaccination programme would need to be carefully designed to prevent the risk of accelerating virus mutations, which could undermine vaccine effectiveness over time.
Vaccination is currently only allowed in licensed UK zoos to protect endangered species. Whether this restriction should be lifted for commercial poultry is a question the government must soon address.
Finding a path forward
The debate over biosecurity vs. vaccination reflects wider tensions between immediate disease control and long-term strategic planning. While vaccination may offer another tool for farmers, it is not a quick fix. The government’s upcoming report will play a central role in determining whether a shift in policy is justified.
As the UK poultry sector waits for clarity, the importance of evidence-based policy and robust oversight cannot be overstated. Any future decisions must safeguard animal health without compromising trade or accelerating viral evolution.
