Recent studies in the U.S. and the U.K. have produced significant evidence to support very limited use of vaccines in dogs and cats. Current recommendations are as follows:
Dog’s and cat’s immune systems are mature by four to six months of
age. The most conservative vaccine schedule would include puppy shots
and a final one year booster.
The “puppy shot combo” is good for at least eight years and should
not be repeated for the life of the dog (or cat). I use the four month
maturity cut-off for my own dogs with no booster as per Dr. Schultz.

Do not re-vaccinate your dog (or cat) with core vaccines. The
bordatella vaccine has shorter (9-12 months) duration. It is required
for boarding although there is little evidence that it will be effective
in warding off infection. Use only the nasal application. If your
dog gets “kennel cough”, it is generally mild and self-limiting and does
not respond to medication, much like the common cold.
Rabies vaccines are required every three years although they last
more like 7 to 10 years. A current challenge is in progress in hopes of
bringing the law into line with current vaccine research. http://www.rabieschallengefund.org/
Other vaccines available but not recommended due to adverse effects and/or lack of effectiveness are:
Lyme vaccine, Coronavirus, Giardiasis, and Rattlesnake envenomation. (Home School of Veterinary Medicine UC Davis).
There are many harmful effects of over vaccination, including:
Autoimmune hemolytic anemia (usually fatal), Brain and nervous system
damage, Encephalitis, Vaccine induced cancers, Anaphylactic shock
(massive allergic reaction), Epilepsy and seizures, Behavioral
problems; anxiety or aggression and Allergies.
These and other adverse effects are being reported from studies compiled by Catherine O’Driscoll canine-health-concern.org.uk
We came across an article about the new drug ProHeart 6 that is being
prescribed for heartworm prevention. A 6 year old healthy dog named
Jack died unexpectedly after receiving the drug ProHeart 6. You can
read more about Jack’s story here.
Don’t be afraid to talk to your veterinarian about your questions and
concerns of over vaccinating. It could not only extend the lifespan of
your dog, but save it’s life.
