Vaccine against feline viral rhinotracheitis, feline calicivirosis, feline panleucopenia and feline leukaemia. Stimulates active immunity against feline rhinotracheitis virus, feline calicivirus, feline panleucopenia virus and feline leukaemia virus. The feline leukaemia vaccine strain is a recombinant canarypox virus expressing the env and gag genes of FeLV-A. Under field conditions, only sub-group A is infective and immunisation against subgroup A provides full protection against A, B and C. After inoculation, the virus expresses the protective proteins, but does not replicate in the cat. As a consequence, the vaccine induces an immune status against feline leukaemia virus.
