For active immunisation of dogs to prevent mortality and clinical signs caused by canine distemper virus infection. To reduce clinical signs of infectious hepatitis and viral excretion due to canine adenovirus type 1 infection. To prevent mortality, clinical signs and viral excretion following canine parvovirus infection. To reduce clinical signs and viral excretion caused by canine parainfluenza virus infection and to reduce clinical signs of respiratory disease and viral excretion following adenovirus type 2 infection.

An onset of immunity to the canine distemper virus, canine adenovirus and canine parvovirus vaccine components of 1 week and an onset of immunity of 4 weeks to the canine parainfluenza virus vaccine component has been demonstrated following use of the vaccine.

A duration of immunity of at least three years has been established for the canine distemper virus, canine adenovirus and canine parvovirus vaccine components. The duration of immunity for the canine parainfluenza virus component has not been demonstrated, but an anamnestic response is produced in dogs given a revaccination one year after basic vaccination. Annual revaccination with the canine parainfluenza virus vaccine component is recommended.
