Vaccination in Rabbits
One of the very best things you can do to give your rabbit a long and healthy life is to ensure that he or she is vaccinated against common and serious infectious diseases.
Like dogs and cats , vaccinations are available for rabbits. The two diseases with vaccines available are myxomatosis and rabbit haemorrhagic disease (RHD). Both indoor and outdoor rabbits may succumb to these diseases.
Myxomatosis
is a viral disease present in the UK since 1953 and is usually fatal in unvaccinated individuals. Prevention involves vaccination and control of vector insects ( mosquitoes, fleas and fur mites). 
Myxomatosis starts with severe conjunctivitis. Next, affected rabbits develop swellings around the head and genital regions, become increasingly weak, go blind,and eventually die.
Treatment is rarely successful. There is also a much less common dry form of the condition which presents with mild lethargy and lumpy lesions on the skin – these cases can be successfully treated.

 Viral Haemorrhagic Disease 
(RVHD) ​

RVHD arrived in Britain in 1992. It is a swift and efficient killer -almost all unvaccinated rabbits who catch RVHD die within a day or two. The virus causes massive internal bleeding. Some rabbits
bleed from the nose and back passage before death, others die so quickly there may be no outward sign of disease at all. Ownersoften think their rabbit has died of “fright”, a “heart attack” or (in summer) “heatstroke”. Most cases are never diagnosed: RVHD is often only suspected when several rabbits die in quicksuccession.
Do RVHD and Myxomatosis vaccinations have side effects?

Like all drugs, vaccines can have side effects, although problems in rabbits are very unusual. Skin reactions are sometimes reported at the site of injection (this was more of a problem with some of the older RVHD vaccines), and some rabbits are quiet for a day or two after vaccination. Although this is not desirable, it’s a whole lot better than death from a preventable disease.
