Whether a rabbit can survive without vaccination depends on the owner's feeding methods and the rabbit's physical condition. Vaccination does not directly affect a rabbit's lifespan. Not all rabbits are vaccinated, and some unvaccinated rabbits live longer than vaccinated rabbits. Vaccination can help rabbits reduce the possibility of illness, but it does not ensure that rabbits are completely resistant to viruses and bacteria. Failure to vaccinate does not mean that they will definitely become infected.

Methods that can increase the life span of rabbits:

1. In the process of raising rabbits, be sure to ensure that the rabbits have a balanced diet, with grass and rabbit food as the main food. Pair it with a small amount of vegetables and fruits, and feed your rabbit water every day.

2. Make sure that the rabbit gets more than an hour of exercise every day. Adequate exercise can enhance the rabbit's physique and improve the body's immunity.

3. The rabbit cage should be cleaned regularly, and the rabbit cage and the areas where rabbits move around should be disinfected frequently to ensure that rabbits live in a clean and hygienic environment.
