Udvalget for Veterinærlægemidler (CVMP) konkluderede, at fordelene ved Purevax FeLV opvejer risiciene til vaccination af katte over otte uger mod felin leukæmi for at forebygge permanent tilstedeværelse af virus i blodet og kliniske tegn på den tilknyttede sygdom, og anbefalede udstedelse af markedsføringstilladelse for Purevax FeLV.
The Committee for Medicinal Products for Veterinary Use (CVMP) concluded that the benefits of Purevax FeLV exceed the risks for active immunisation of cats eight weeks of age or older against feline leukaemia for the prevention of persistent viraemia and clinical signs of the related disease, and recommended that Purevax FeLV be given a marketing authorisation.
