A postal survey of all registered cattle and sheep farmers in East Anglia was carried out from July 2008 to determine bluetongue virus serotype 8 (BTV-8) vaccine uptake in the region. The vaccine was available to farmers in this region from May 2008. The survey was repeated in Cumbria and Northumberland at the beginning of 2009. In these regions, the vaccine was not available until September 1, 2008. Holding-level vaccine uptake was estimated to be 85 per cent (95 per cent confidence interval [CI] 83 to 87 per cent, n=1623) in East Anglia and 36 per cent (95 per cent CI 32 to 40 per cent, n=633) in northern England. A telephone follow-up of non-responders reduced these estimates to 79 and 29 per cent in East Anglia and northern England, respectively. In both regions, vaccine coverage was higher in sheep than in cattle, with 92 per cent of sheep in East Anglia having been vaccinated. The proportion of holdings that had applied the vaccine or were intending to apply the vaccine in 2009 in the northern region was 51 per cent (95 per cent CI 47 to 54 per cent, n=664), with a further 37 per cent undecided at the time of response.
