Excellent information, Dr. Lee!
The American Veterinary Medical Association actually established the
Vaccine-Associated Feline Sarcoma Task Force in 1996 "
in response to the increased incidence of soft tissue sarcomas occurring at vaccination sites." This link will take you to the AVMA website

2001
Report of the Vaccine-Associated Feline Sarcoma Task Force, which states that: "
Most killed-virus vaccines contain adjuvants to enhance the immune response, and injection of some killed-virus vaccines has been shown to result in inflammatory granulomas in cats.2 Some of these inflammatory granulomas to progress to sarcomas.3"
Rabies vaccines are killed, adjuvanted vaccines.
