Vaccines cause cancer in cats at their injection site and, according to the Journal of Veterinary Medicine,August 2003, vaccines cause cancer in dogs at their injection sites. Vaccines cause autoimmune haemolytic anaemia (JVM, Vol 10, No. 5, September/ October 1996; Merck Veterinary Manual), andarthritis (BVJ, May 1995 and Am Coll Vet Intern Med, 2000; 14:381). Epilepsy is a symptom of encephalitis, which, as we already know, can be caused by vaccines.
According to Dr Larry Glickman and his team at Purdue University, serum and foreign proteins in vaccines can cause autoimmunity (i.e. cancer, leukaemia, organ failure, etc.). This research also indicates that genetic damage is possible, since vaccinated dogs developed autoantibodies to attack their own DNA. Research from the University of Geneva echoes this finding.
According to Dr Jean W Dodds, an eminent vet and researcher, both allergic and autoimmune diseases have been rising since the introduction of modified live virus vaccines. Autoimmune diseases are where the body attacks self; they include cancer, leukaemia, thyroid disease, Addisons, Grave’s disease, autoimmune haemolytic anaemia, rheumatoid arthritis, diabetes, lupus, thrombocytopenia, organ failure, skin inflammations, and more.
Vaccinations have saved many pets’ lives over the years, but they aren’t without risk. Now, with new research showing that immunity may last longer than once thought, veterinary experts say it’s safer to decrease the frequency of most shots that typically have been given every year.
Veterinarians have suspected for years that annual vaccinations for cats and dogs aren’t necessary, but large, well-controlled studies just didn’t exist to prove it one way or the other. With the exception of rabies vaccine, the U.S. Department of Agriculture doesn’t require data beyond one year for any vaccine.
Three-year interval recommended
“Current vaccine protocol is to properly immunize puppies and kittens with two or three doses, starting later than we used to, maybe at eight weeks and not earlier than six weeks,” Dodds says. “Then you can give a booster at one year and either repeat it every three years, stagger it by giving one vaccine per year instead of combination vaccines, or do titers instead.” Titers are tests that measure the level of antibodies in the blood, which would indicate that immunity still exists.
That recommended three-year interval was a compromise decision. “Annual boosters for the core vaccinations are excessive for most dogs and cats,” says veterinarian Link Welborn of North Bay Animal and Bird Hospital in Tampa, Fla., and a member of the most recent panel of veterinarians that revised vaccination guidelines for dogs and cats. “Limited studies suggest that booster vaccinations for many of the core vaccinations last for at least seven years. However, given the limited number of animals involved in these studies, three years seemed like a reasonable compromise.”
There’s also an advantage to giving single rather than combination vaccines. “Giving more vaccinations increases the likelihood of side effects,” Welborn says. “Separating vaccinations allows the veterinarian to determine which vaccine caused a side effect if one occurs.”
If you’re concerned that your dog or cat will develop a vaccine-related health problem, but you want to make sure they’re protected against disease, annual titers are an economical alternative.
You’ve undoubtedly seen them in your mailbox. Cute little reminder cards from your vet that it’s time for Beauregard’s annual vaccinations. But after looking a bit closer at the risks and benefits of these vaccines, you might want to paws before making that appointment.
Could these vaccines not only be unnecessary, but actually harmful to your pet’s health?
A study of more than 2,000 cats and dogs in the United Kingdom by Canine Health Concern showed a 1 in 10 risk of adverse reactions from vaccines. This contradicts what the vaccine manufacturers report for rates of adverse reactions, which is “less than 15 adverse reactions in 100,000 animals vaccinated” (0.015 percent).
Additionally, adverse reactions of small breeds are 10 times higher than large breeds, suggesting standard vaccine doses are too high for smaller animals.
Results—4,678 adverse events (38.2/10,000 dogs vaccinated) were associated with administration of 3,439,576 doses of vaccine to 1,226,159 dogs. The VAAE rate decreased significantly as body weight increased. Risk was 27% to 38% greater for neutered versus sexually intact dogs and 35% to 64% greater for dogs approximately 1 to 3 years old versus 2 to 9 months old. The risk of a VAAE significantly increased as the number of vaccine doses administered per office visit increased; each additional vaccine significantly increased risk of an adverse event by 27% in dogs ≤ 10 kg (22 lb) and 12% in dogs > 10 kg.
Conclusions and Clinical Relevance—Young adult small-breed neutered dogs that received multiple vaccines per office visit were at greatest risk of a VAAE within 72 hours after vaccination. These factors should be considered in risk assessment and risk communication with clients regarding vaccination. (J Am Vet Med Assoc 2005;227:1102–1108)
