they destroy it
Because when Edward Jenner invented the vaccination, no one knew how it worked or what the side effects and risks were, so everyone was very skeptical about vaccinations. When Pasteur discovered microbes, he found how they and indeed vaccinations worked, and from there calculated that vaccinations could work against other diseases caused by the various differtent microbes he discovered, by using weakened or dead microbe antigens to boost the immune system.

The stomach contains acids that defend your body against microbes. Most of these microbes are destroyed once they are digested and enter into the acidic stomach.
Some Microbes can help us to live healthily by fighting against other harmful microbes or germs.
Skin is the outer covering of the body that protects against microbes and germs.

Dwarf rabbits need the same vaccinations as all pet rabbits. What vaccinations are required for your pet rabbit depends on where you live. In the UK, rabbits require two vaccinations: one against Myxomatosis and the other against VHD (Viral Hemorrhagic Disease). there should be two weeks between the administration of these vaccinations. In many parts of North America, however, no vaccinations are required (or even available) for rabbits at all. Contact a local pet rabbit organization or a "rabbit-savvy" vet to find out what vaccinations are required for rabbits in your area.
