Protecting Your Rabbit Against Rabbit Calicivirus (Rabbit Viral Haemorrhagic Disease)
Vaccinating your rabbit is one of the most important ways to protect them from Rabbit Viral Haemorrhagic Disease (RHDV), commonly known as rabbit calicivirus. This highly contagious viral disease is widespread throughout Australia and can affect both indoor and outdoor rabbits.
At The Rabbit Doctors, we recommend annual rabbit vaccinations as part of your rabbit's regular health check. During your rabbit's vaccination appointment, one of our experienced rabbit veterinarians will also perform a thorough health check to ensure your bunny is healthy and answer any questions you may have about their care.
Frequently Asked Questions About Rabbit Vaccinations
What Is Filavac?
At The Rabbit Doctors, we use Filavac VHD K C+V, an inactivated rabbit vaccine that protects against both Rabbit Haemorrhagic Disease Virus Type 1 (RHDV1) and Rabbit Haemorrhagic Disease Virus Type 2 (RHDV2).
What Is Rabbit Calicivirus (Rabbit Viral Haemorrhagic Disease)?
Rabbit Viral Haemorrhagic Disease (RHDV), often referred to as rabbit calicivirus, is a highly contagious viral disease that causes severe internal bleeding and sudden death in rabbits. It is transmitted by flies over long distances as well as contact with urine or faeces from infected rabbits.
The original strain (RHDV1) is fatal in over 99% of unvaccinated rabbits. More recently, a newer strain known as RHDV2 has become established in Australia. Some rabbits will survive RHDV2 but many who contract the virus will still not survive and vaccination is strongly recommended.
Many rabbits infected with rabbit calicivirus show very few signs before becoming critically ill, making prevention through vaccination extremely important. It can be difficult to rule out calicivirus in an unwell unvaccinated bunny and this slows access to important and life saving care.
How Is Rabbit Calicivirus Spread?
Rabbit calicivirus spreads very easily and can be carried into your home even if your rabbit never goes outside.
The virus can be spread by:
- Flying and biting insects, including flies and mosquitoes
- Clothing and shoes
- Car tyres
-
Other contaminated surfaces
Because of this, indoor rabbits are still at risk of exposure and should also be vaccinated.
When Should My Rabbit Be Vaccinated?
Filavac is first given at 10 weeks of age.
Your rabbit develops immunity approximately 7 days after vaccination, and protection lasts for 12 months.
To maintain protection, rabbits should receive a booster vaccination every 12 months for life.
Why Should My Rabbit Have 6 Monthly Health Checks?
Even though rabbit vaccinations are given annually, we recommend general health checks every six months.
Rabbits are prey animals and are very good at hiding signs of illness. Regular health checks allow our rabbit veterinarians to detect subtle health changes early, often before they become obvious at home.
These appointments are also an excellent opportunity to discuss your rabbit's diet, weight, dental health, behaviour, housing, and overall wellbeing.
Are There Any Side Effects After Rabbit Vaccination?
The older vaccination had a number of side affects for some bunnies. The Filavac has much milder side affects and this is less frequent than seen with the older vaccine.
Like any vaccination, mild side effects can occasionally occur, including:
- A mild fever
- Lethargy
- A small lump (subcutaneous nodule) at the vaccination site
These side effects are generally mild and short-lived. If you have any concerns after your rabbit's vaccination, please contact our veterinary team.
