Rabbit Welfare: Myxomatosis and RHDV Vaccination (UK 2026)

Myxomatosis and Rabbit Haemorrhagic Disease Virus (RHDV) cause horrific suffering in unvaccinated domestic rabbits, with annual vaccination the primary preventive measure available to UK rabbit owners.

Key Facts

Myxomatosis causes swelling of the eyes, nose and genitals, blindness, and death over 10-14 days in unvaccinated rabbits
RHDV2 (Rabbit Haemorrhagic Disease Virus type 2) causes sudden death from internal haemorrhage and is spreading across the UK
Annual vaccination with Nobivac Myxo-RHD Plus covers both diseases in a single injection
Wild rabbits are a reservoir for myxomatosis; outdoor rabbits are at highest risk but indoor rabbits can also be exposed via insects

Welfare Considerations

Myxomatosis in unvaccinated rabbits causes severe suffering — blindness, inability to eat and drink, respiratory distress, and secondary bacterial infections over 1-2 weeks. RHDV2 causes a more acute but no less distressing death from disseminated intravascular coagulation. Unvaccinated rabbits that contract these diseases typically require euthanasia. Both diseases are entirely preventable through annual vaccination, yet vaccination rates in UK domestic rabbits remain suboptimal due to cost and owner unawareness.
