Over the last few
years, a new strain of Rabbit Viral Haemorrhagic Disease
(RVHD-2) from Europe has been spreading through the UK. While
less serious than the original RVHD-1 strain which tends to
kill 100% of infected rabbits, the new RVHD-2 strain can cause
severe illness and and results in death in up to 25% of
infected rabbits. The current combined Nobivac MyxoRHD vaccine
only covers myxomatosis and RVHD-1. It does not offer
protection against the new RVHD-2 strain. Filavac KC+V, a new
vaccine from Europe that covers RVHD-2 is now available to our
clients. This vaccine does not include protection against
myxomatosis and therefore, rabbits will need both vaccines.
What is the difference between RVHD-1 and RVHD-2?
RVHD-1 is fatal in 100% of affected animals and signs
of illness are rarely seen before the animal dies. RVHD-2
takes longer and therefore clinical signs of illness including
anorexia, weight loss, bleeding, seizures, fever and jaundice
may be seen. The mortality rate can be 25%.
What are the signs of RVHD-2?
Bleeding under the skin or from the mouth, anus or
vulva. Anorexia, weight loss, internal bleeding, seizures,
fever, jaundice and results. Death in up to 25% of infected
How is it spread?
The virus is spread through direct contact with other
rabbits, saliva, urine, faeces, clothing, shoes and other
objects as well as grass and plants. Insects can also spread
Why do I need to use both the Nobivac MyxoRHD and
Filavac RHD KC+V vaccines?
Both outdoor and indoor rabbits are at risk of
myxomatosis, a very common, fatal disease of rabbits spread by
fleas and biting insects. Filavac does not offer any
protection against myxomatosis.
Can I have both vaccines done at the same time?
No. We advise a 2 week gap between the vaccines in
order to allow time for the immune system to respond to both
What are the side-effects of Filavac RHD KC+V?
The main reported side-effect is development of a small
skin nodule at the injection site that may last up to 2
months. Although, not a UK vaccine, Filavac has been used for
several years in Europe.
What age can rabbits be vaccinated and how long
until they are protected?
From 10 weeks of age. Rabbits should have immunity
after 7 days following the injection
How many injections are needed for the primary
1 injection, as long as the rabbits are over 10 weeks
How long does protection last?

animals, for full protection the manufacturers recommend a
booster every 6 months
