Thank you -- you are a very open-minded, progressive veterinarian, do your clients realize how fortunate they are? I am sure the forum members do!
You probably were already aware that "The World Health Organization (WHO) in 1999 classified veterinary vaccine adjuvants as Class III/IV carcinogens with Class IV being the highest risk,
" IARC Monographs on the Evaluation of Carcinogenic Risks to Humans: Volume 74, World Health Organization, International Agency for Research on Cancer, Feb. 23-Mar. 2, 1999, p. 24, 305, 310.)
Regarding the vaccine associated sarcomas in cats,
the American Veterinary Medical Association actually established a Vaccine-Associated Feline Sarcoma Task Force in 1996 "in response to the increased incidence of soft tissue sarcomas occurring at vaccination sites."

will take you to the 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"
According to the 2003 American Animal Hospital Association's Canine Vaccine Guidelines http://www.leerburg.com/special_report.htm
(Page 16), "...killed vaccines are much more likely to cause hypersensitivity reactions (e.g., immune-mediated disease)." Could this be due to the combination of mercury (thimersol) and aluminum additives in the same vaccine?
For the benefit of others you may not know, rabies vaccines are killed, adjuvanted vaccines.
