The Australian Pesticides and Veterinary Medicines Authority (APVMA) has approved an emergency permit (PER92219) for a vaccine to protect pet rabbits against the rabbit haemorrhagic disease (calicivirus) virus type 2 strain (RHDV2).

The emergency permit for the Filavac VHD K C+V vaccine is in force until 31 May 2024 and provides for the active immunisation of pet rabbits from 10 weeks of age to reduce mortality rates caused by the RHDV2 and RHDV1 (classical) virus strains.

The manufacturer of Filavac VHD K C+V, FILAVIE, has submitted an application for registration of the vaccine, which is currently under assessment by the APVMA. The vaccine has a current Marketing Authorisation in Europe with an approved onset of immunity of one week and a duration of immunity of one year. Under the conditions of the emergency permit, the vaccine will be supplied in Australia through Ceva Animal Health Pty Ltd.
