We know that the risk of a cat developing a vaccine-induced or related sarcoma is around 1 in 10,000. However, these sarcomas are extremely aggressive and are difficult to treat. Some veterinary schools have already started implementing tail vaccines in cats. The idea is that if the cat develops a sarcoma in the tail, the tail can be amputated, thus making it easier to cure the cancer.
This all sounds great, but just wondering how cats are going to react to getting vaccines in their tail. Anyway, something to think about and this may be the new way of feline vaccinations in the future! Please check out this article that was recently published on the subject:
