As you may be aware, there have been a number of outbreaks of this disease in Melbourne and Mildura since 2014 and FPV has now struck in Sydney, predominantly in shelter-housed cats/kittens, as reported by a number of sources including the University of Sydney and the Australian Veterinary Association (AVA).
The January 2017 release by the AVA (attached, reproduced) indicates that:
  1. Current FPV vaccines are protective; and
  2. Unvaccinated/incompletely vaccinated kittens are most at risk
Current vaccination requirements for exhibiting at NSW CFA shows
While NSW CFA has no immediate plan to alter our current vaccination (show) requirements to include adults, we are reviewing the situation and will continue to monitor developments and veterinary opinion.
In the meantime, we urge you to consult with your veterinarians about adequate protection from FPV and to ensure that vaccinations for all of your cats/kittens are current.
