Do Small Pets Need Vaccinations?
🤎 The short version: most small pets don’t have any routine vaccines — but two do, and for them vaccination is essential. Rabbits need vaccinating against myxomatosis and Rabbit (Viral) Haemorrhagic Disease; ferrets need annual rabies and canine distemper. For every other small pet, there’s no vaccine, which makes early vet care and prevention your main tools. Here’s the honest, species-by-species picture.
The two that need vaccinating
Rabbits. The RSPCA recommends vaccinating against myxomatosis and Rabbit (Viral) Haemorrhagic Disease (R(V)HD) — serious, usually fatal viral diseases spread by biting insects and contaminated objects (so even indoor rabbits are at risk). This is routine, often life-saving care, typically an initial course plus yearly boosters. We cover it in full in do rabbits really need vaccinations?
Ferrets. Ferrets need annual rabies and canine distemper vaccinations (not given on the same day). Distemper is almost always fatal in ferrets, so this isn’t optional — a ferret-experienced vet will set the schedule for where you live.
The many that don’t
There are no routine vaccines for pet:
- rats, mice, hamsters, gerbils (rodents),
- guinea pigs, chinchillas, degus (the other grazers/rodents),
- hedgehogs and sugar gliders.
This isn’t a gap in your care — it’s simply that vaccines don’t exist for these species’ common illnesses.
Why “no vaccine” raises the stakes on prevention
For the unvaccinated species, there’s no jab standing between your pet and illness — so early veterinary care is the main defence. That’s exactly why the care guides stress:
- Learning their normal (appetite, weight, droppings, breathing) so you catch problems early,
- Finding an exotic vet before you need one (many common antibiotics are dangerous to rabbits, guinea pigs and hamsters),
- Prevention through husbandry — clean low-ammonia housing to prevent respiratory infection, the right diet, correct temperature and social setup.
For rats especially, with no vaccine available, prompt vet care and clean housing are the whole defence against their common respiratory and tumour problems.
The honest takeaway
If you keep a rabbit or a ferret, vaccination is core, non-negotiable care — book it in. If you keep any other small pet, there’s nothing to vaccinate, so put that energy into an exotic vet, learning their normal, and good husbandry. See each animal’s care guide for its specific health needs.

Common questions
Which small pets need vaccinations?
Rabbits and ferrets. Rabbits need vaccinating against myxomatosis and Rabbit (Viral) Haemorrhagic Disease, and ferrets need annual rabies and canine distemper vaccinations. Most other small pets — rats, mice, hamsters, gerbils, guinea pigs, chinchillas, degus, hedgehogs and sugar gliders — have no routine vaccines available.
Do rats and other rodents need vaccinations?
No — there are no routine vaccines for pet rats, mice, hamsters, gerbils, guinea pigs, chinchillas or degus. Because there’s no vaccine, early veterinary care is the main defence against illness, so learning their normal and finding an exotic vet matters even more.
Do indoor rabbits still need vaccinations?
Yes. The viruses rabbits are vaccinated against spread via biting insects and contaminated objects like clothing and shoes, so even house rabbits are at risk. Vaccination is core care for any pet rabbit, indoors or out.
What vaccinations do ferrets need?
Ferrets need annual rabies and canine distemper vaccinations (not given on the same day). Distemper is almost always fatal in ferrets, so vaccination is essential — ask a ferret-experienced vet about the schedule for your area.
