Abstract

<abstract abstract-type="main" xml:lang="en" id="tbed12048-abs-0001"> <title>Summary</title> <p>Sixteen sheep and 18 cattle were followed up during 1 year to estimate the duration of immunity induced by inactivated bluetongue virus serotype 8 (BTV‐8) vaccines (sheep and cattle) and a bluetongue virus serotype 1 (BTV‐1) vaccine (cattle) under field conditions using cELISA and seroneutralization test (SNT). Four sheep never seroconverted. Those that seroconverted were all seronegative by BTV‐8 SNT at the date of last sampling [378 days post‐vaccination (dpv)]. Eight sheep were still positive by competitive ELISA (cELISA) 378 dpv. All the cattle seroconverted. At the end of the study, eight and 11 cattle were still positive by BTV‐8 SNT and cELISA, respectively (335 dpv); and nine were still positive by BTV‐1 SNT (301 dpv).</p> </abstract>
