Generally, hamsters don't need to be vaccinated. At present, there are no vaccines specifically designed for hamsters. Moreover, pet hamsters usually don't carry viruses, so vaccination is not necessary. If hamsters are given vaccines that are not suitable for them, it may lead to serious adverse reactions.
Although hamsters don't require vaccines in the traditional sense, under certain special circumstances, such as when a hamster has serious health problems or needs to receive certain treatments, a veterinarian may recommend vaccinating it with specific vaccines to enhance its immunity. Additionally, it's very important to keep the hamster's living environment clean and hygienic. Regularly cleaning the cage, changing the clean bedding, and providing fresh food can effectively prevent the occurrence of diseases.
When handling hamsters, pet owners should maintain good personal hygiene habits to avoid bringing external bacteria or viruses into the hamster's living environment. If bitten by a hamster, although the probability of contracting rabies virus is extremely low, for safety's sake, it is recommended to disinfect the wound promptly and consider getting a tetanus vaccine.
