Survey reveals UK farmers divided on bluetongue vaccination as concerns persist
Initial findings from a UK-wide survey reveal that more than half of livestock keepers remain undecided about vaccinating their animals against bluetongue virus (BTV-3). However, a significant portion intends to vaccinate before the summer of 2025.
The survey, conducted by UK independent industry-based body Ruminant Health & Welfare in collaboration with Flock Health Ltd, the Agriculture and Horticulture Development Board (AHDB), and the University of Nottingham, explores the impact of BTV-3 on livestock health and its broader implications for farm operations.
Farmers have expressed concerns over vaccine efficacy, the timing of vaccination, the duration of immunity, and potential trade and cost implications. Fiona Lovatt, of sheep veterinary consultancy Flock Health Ltd, explained: "With bluetongue restrictions impacting movements, and increasingly, clinical signs being observed, it isn't surprising that UK farmers have a lot of questions about vaccines."
The survey suggests that sheep farmers are more likely to vaccinate than cattle farmers, reflecting the higher mortality rates observed in unvaccinated sheep flocks across Europe. Research from Germany indicates mortality rates in unvaccinated sheep flocks have reached as high as 30%, while vaccinated flocks reported much lower losses, ranging from 1-2%.
Lovatt addressed farmer concerns, clarifying that while BTV-3 can negatively affect fertility, there is no evidence to suggest that well-timed vaccination impacts fertility in sheep or cattle.
The findings come as the AHDB prepares to launch a vaccination awareness campaign to encourage farmers and veterinarians to engage in timely discussions about the benefits of vaccination.
Beyond its health implications, BTV-3 has had significant economic impacts on farmers. Survey respondents reported financial challenges, including difficulties accessing markets due to movement restrictions in affected zones. This has compounded issues such as securing sufficient feed and forage for the winter months.
Additionally, the emotional toll on farmers has been significant. Many reported distress from dealing with livestock mortality and the financial losses associated with the disease. One respondent, who experienced losses due to BTV-3, described the ordeal as "horrible; physically, financially, mentally and emotionally."
As the UK grapples with the impacts of BTV-3, the survey highlights the urgent need for greater clarity and guidance on vaccination strategies to support livestock keepers.
