Vaccinations Not Recommended For Dogs
By: Dr. Bob Rogers D.V.M.
Multiple components in vaccines compete with each other for the immune system and result in lesser immunity for each individual disease as well as increasing the risk of a reaction.
Canine corona virus is only a disease of puppies less than six weeks of age (15- p20). It is a rare, self-limiting disease (i.e. dogs get well in 3 days without treatment)(3). Corona virus does not cause disease in adult dogs.
Cornell University and Texas A&M University have only diagnosed one case each in the last 7 years. For a veterinarian to make a diagnosis of Corona Virus based on clinical signs is highly presumptive. Only electron
microscopy of feces can verify canine corona virus. This is only done at places such
as Texas A & M Diagnostic Laboratory.
Immunologists have reason to believe that the vaccine does not work. Mucosal secretory IgA antibodies would be necessary to protect a dog against this disease & an injectable vaccine will not provide this type of
protection.(13,19- p18, 21) I see no justification for the use of corona virus
vaccine.
In 1985 a significant number of dogs died from encephalitis caused by Corona Virus vaccine. (3, 21) An unfortunate & heartbreaking catastrophe caused by an unnecessary vaccine.
Leptospirosis vaccine is a common cause of adverse reactions in dogs ranging from life threatening anaphylactic reactions to mild facial swelling and urticaria. Most of the clinical cases of leptospirosis reported in dogs in the U.S. are caused by serovars (or types) grippotyphosa, L. pomona and L.
bratislava.(1,9, 15-p20, 21) The vaccines contain different serovars canicola and
ictohemorrhagica! Cross protection is not provided and protection is short-lived.(19)
New Vaccines recently by Fort Dodge include - L. grypothyposa. I still do not recommend these vaccines. Records at Texas A & M
Diagnostic Lab showed no cases of Leptospirosis in dogs in Texas in 1999.
This vaccine should not be given to puppies less than 16 weeks of age as they are very immunosuppressive. They can interfere with immunization against parvo & distemper. The risk of side effects outway any benefits.
Side effects to Lymes disease vaccine include kidney damage and immune mediated joint disease. Because of the questionable efficacy & common side effects, most veterinary schools do not recommend this vaccine.
Lyme disease prevention should emphasize early removal of ticks. Ticks must be attached to the dog for 24 hrs to transmit the disease. Amitraz collars are more effective than Top Spot as amitraz paralyzes the ticks mouth parts preventing transmission of disease (11). Top Spot or Frontline takes 24-48 hours to kill ticks allowing for the possibility of disease transmission.
Vaccinating pets against lyme disease does not provide any protection for the owners.

According to Dr. Schultz in the Journal of the AVMA Aug. 15. 1995, when a vaccination series given at 2, 3, and 4 months and again at 1 year with a modified live virus, puppies and kittens program memory cells that
survive for life, providing lifelong immunity (6, 15, 20, 21).
Dr. Leland Carmichael at Cornell University and Dr. Schultz have studies showing immunity against challenge at 7 years for canine distemper and 7 years for parvovirus; and immunity by serology out to 15 years. (22). Studies for longer duration are pending (5, 13, 14, 15, 18, 22).
There are no new strains of parvovirus as one manufacturer would like to suggest. Parvovirus vaccination provides cross immunity for all types.
Hepatitis (Adenovirus)- (CAV2) is one of the agents known to be a cause of "kennel cough." Only vaccines with CAV-2 should be used as CAV-1 vaccines carry the risk of "hepatitis blue-eye" reactions and kidney damage.
Hepatitiis (CAV1) in dogs is a very rare disease.
Bordetella Parainfluenza Commonly called "kennel cough," this vaccine is
recommended only for those dogs boarded, groomed, taken to dog shows,or for any reason housed where exposed to a lot of dogs. The intranasal vaccine provides more complete and more rapid onset of immunity with less chance of reaction (23).
Immunity requires 72 hours and does not protect from every cause of "kennel cough." Immunity to bordetella is of short duration
(4-6 months), so vaccination should be repeated as needed. Dogs kept at home are
at very low risk for these diseases, so vaccination is not necessary.

New Principles of Immunology
Dogs' & cats' immune systems mature fully at 6 months. If a modified live virus (MLV) vaccine is given after 6 months of age, it produces an immunity which is good for the life of the pet (i.e. canine distemper, parvo, feline distemper)(15- p35, 20, 21, 23) If another MLV vaccine is given a year
later, the antibodies from the first vaccine neutralize the antigens of second vaccine, and there is little or no effect (8,15,16,19) The titer(level of immunity) is not "boosted" nor are more memory cells induced.
Not only are annual boosters for parvo and distemper unnecessary (6),they subject the pet to potential risks of allergic reactions & immune mediated hemolytic anemia (4, 21) (a disease where the dog rejects its' own
blood -shown to be caused by MLV vaccines.
There is no scientific documentation to back up label claims forannual administration of modified live virus vaccines.
Puppies receive antibodies through their mother's milk (colostrum)the very first time they nurse. This natural protection can last 8 - 14 weeks.Puppies & kittens should not be vaccinated at less than 8 weeks. Maternal
immunity will neutralize the vaccine & little protection (0 -35%) will be produced
(6,7, 11, 13, 20, 21, 23).
