Myxo Rhd Vaccine

Nobivac Myxo-RHD Plus is a vaccine used in rabbits to reduce death and clinical signs due to myxomatosis and rabbit haemorrhagic disease (RHD). Myxomatosis is caused by the myxoma virus and is spread between rabbits by close contact and biting insects such as fleas and mosquitoes. The virus causes swelling and discharge from the eyes, nose and bottom with most rabbits dying within 10 – 14 days. RHD, caused by classical RHD virus (RHDV1) and RHD type 2 virus (RHDV2), leads to blood clots in major organs such as the heart, lungs and kidneys leading to heart and respiratory failure when the heart and lungs do not work properly. Nobivac Myxo-RHD Plus contains live myxoma vectored RHD virus strains 009 and MK1899.

To be fully protected, rabbits need to be vaccinated against Myxomatosis and both types of viral haemorrhagic disease (RHD1 and RHD2). This can now be done with a single injection. Historically there were separate vaccinations required, which was confusing for rabbit owners.


Nobivac Myxo-RHD PLUS will make vaccination more convenient, helping improve levels of compliance against variant strains of RHD which is currently estimated to be at around only 60 percent of the vaccinated rabbit population. A single low volume 0.5ml vaccination provides 12 months of duration of immunity against all three pathogens. Available in a pack of five, single dose vials, with a shelf-life of two years, the vaccine can be used from the age of five or seven weeks onwards to achieve the full duration of immunity. Immunity is provided within three weeks of administration.

Leonora Bell, Product Manager at MSD Animal Health comments: “It’s clear that this year the usually busy Spring season, where purchasing and vaccinating rabbits is at its highest, will not be as predictable as previous years. Vaccinating rabbits is unlikely to be at the top of your agenda. MSD Animal Health’s new Nobivac Myxo-RHD PLUS has arrived, however, so this is a good opportunity to understand how to safely switch vaccinated rabbits and introduce new rabbits to vaccination. This is a time when clients can be encouraged back into your practice, ideally prior to the increase in infectious disease which we tend to see during the peak summer months.”

Benefits of Myxo Rhd Vaccine

Four laboratory studies were conducted in young rabbits that showed protection began three weeks after vaccination and lasted 12 months against RHDV1 and RHDV2. For myxoma virus, rabbits were tested for antibodies only. Antibody levels increased for up to six weeks following vaccination and stayed at this level for 12 months. In addition, the company also presented field studies with the already authorised vaccine Nobivac Myxo-RHD which contains live myxoma vectored RHD virus strain 009 only. These studies showed that rabbits that were vaccinated with Nobivac Myxo-RHD had fewer signs of myxomatosis, more antibodies against RHDV1 virus in their blood and a lower death rate than unvaccinated rabbits.
