Despite the success of vaccination against myxoma virus, myxomatosis remains a problem on rabbit farms throughout Spain and Europe. In this study we set out to evaluate possible causes of myxoma virus (MYXV) vaccine failures addressing key issues with regard to pathogen, vaccine and vaccination strategies. This was done by genetically characterising MYXV field isolates from farm outbreaks, selecting a representative strain for which to assay its virulence and measuring the protective capability of a commercial vaccine against this strain. Finally, we compare methods (route) of vaccine administration under farm conditions and evaluate immune response in vaccinated rabbits. The data presented here show that the vaccine tested is capable of eliciting protection in rabbits that show high levels of seroconversion. However, the number of animals failing to seroconvert following subcutaneous vaccination may leave a large number of rabbits unprotected following vaccine administration. Successful vaccination requires the strict implication of workable, planned, on farm programs. Following this, analysis to confirm seroconversion rates may be advisable. Factors such as the wild rabbit reservoir, control of biting insects and good hygienic practices must be taken into consideration to prevent vaccine failures from occurring. (C) 2015 Elsevier B.V.
