New Vaccination Protocols in America

VACCINATION NEWS FLASH

I would like to make you aware that all 27 veterinary schools in North America are in the process of changing their protocols for vaccinating dogs and cats. Some of this information will present an ethical & economic challenge to vets, and there will be sceptics.

Some organizations have come up with a political compromise suggesting vaccinations every 3 years to appease those who fear loss of income vs. those concerned about potential side effects. Politics, traditions, or the doctor's economic well being should not be a factor in medical decision.

NEW PRINCIPLES OF IMMUNOLOGY

"Dogs and cats immune systems mature fully at 6 months. If a modified live virus vaccine is given after 6 months of age, it produces an immunity which is good for the life of the pet (ie: canine distemper, parvo, feline distemper). If another MLV vaccine is given a year later, the antibodies from the first vaccine neutralize the antigens of the second vaccine and there is little or no effect. The titer is not "boosted" nor are more memory cells induced." Not only are annual boosters for parvo and distemper unnecessary, they subject the pet to potential risks of allergic reactions and immune-mediated hemolytic anemia. "There is no scientific documentation to back up label claims for annual administration of MLV vaccines." Puppies receive antibodies through their motherís milk. 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 and little protection (0-38%) will be produced. Vaccination at 6 weeks will, however, delay the timing of the first highly effective vaccine. Vaccinations given 2 weeks apart suppress rather than stimulate the immune system. A series of vaccinations is given starting at 8 weeks and given 3-4 weeks apart up to 16 weeks of age. Another vaccination given sometime after 6 months of age (usually at 1 year 4 mo) will provide lifetime immunity.

CURRENT RECOMMENDATIONS FOR DOGS

Distemper & Parvo
"According to Dr. Schultz, AVMA, 8-15-95, when a vaccinations series given at 2, 3 & 4 months and again at 1 year with a MLV, puppies and kitten program memory cells that survive for life, providing lifelong immunity." Dr. Carmichael at Cornell and Dr. Schultz have studies showing immunity against challenge at 2-10 years for canine distemper & 4 years for parvovirus. Studies for longer duration are pending. "There are no new strains of parvovirus as one mfg. would like to suggest. Parvovirus vaccination provides cross immunity for all types." Hepatitis (Adenovirus) 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 & kidney damage.

Bordetella Parainfluenza: Commonly called "Kennel cough" 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. Immunity requires 72 hours and does not protect from every cause of kennel cough. Immunity is of short duration (4 to 6 months).

RABIES
There have been no reported cases of rabid dogs or cats in Harris, Montogomery or Ft. Bend Counties [Texas], there have been rabid skunks and bats so the potential exists. It is a killed vaccine and must be given every year.

Lyme disease is a tick born disease which can cause lameness, kidney failure and heart disease in dogs. Ticks can also transmit the disease to humans. The original Ft. Dodge killed bacteria has proven to be the most effective vaccine. Lyme disease prevention should emphasize early removal of ticks. Amitraz collars are more effective than Top Spot, as amitraz paralyzes the tick's mouth parts preventing transmission of disease.

VACCINATIONS NOT RECOMMENDED
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. It is rare, self limiting (dogs get well in 3 days without treatment). Cornell & Texas A&M have only diagnosed one case each in the last 7 years. Corona virus does not cause disease in adult dogs.

Leptospirosis vaccine is a common cause of adverse reactions in dogs. Most of the clinical cases of lepto reported in dogs in the US are caused by serovaars (or types) grippotyphosa and bratsilvia. The vaccines contain different serovaars eanicola and ictohemorrhagica. Cross protection is not provided and protection is short lived. Lepto vaccine is immuno-supressive to puppies less than 16 weeks.



NEW RECOMMENDATIONS FOR CATS

Feline vaccine related Fibrosarcoma is a type of terminal cancer related in inflammation caused by rabies & leukemia vaccines. This cancer is thought to affect 1 in 10,000 cats vaccinated. Vaccines with aluminum adjuvant, an ingredient included to stimulate the immune system, have been implicated as a higher risk. We now recommend a non-adjuvanted rabies vaccine for cats. Testing by Dr. Macy, Colorado State, has shown this vaccine to have the lowest tissue reaction and although there is no guarantee that a vaccine induced sarcoma will not develop, the risk will be much lower than with other vaccines.

Program injectable 6 mo flea prevention for cats has been shown to be very tissue reactive & therefore has the potential of inducing an injection site fiborsarcoma. If your cats develops a lump at the site of a vaccination, we recommend that it be removed ASAP, within 3-12 weeks.

Feline Leukemia Virus Vaccine
This virus is the leading viral killer of cats. The individuals most at risk of infection are young outdoor cats, indoor/outdoor cats and cats exposed to such individuals. Indoor only cats with no exposure to potentially infected cats are unlikely to become infected. All cats should be tested prior to vaccination. Cats over one year of age are naturally immune to Fel.V whether they are vaccinated or not, so annual vaccination of adult cats is NOT necessary. The incubation period of Feline leukemia can be over 3 years, so if your cat is in the incubation state of the disease prior to vaccination, the vaccine will not prevent the disease.

Feline Panleukopenia Virus Vaccine.
Also called feline distemper is a highly contagious and deadly viral disease of kittens. It's extremely hardy and is resistant to extremes in temperature and to most available disinfectants. Although an effective treatment protocol is available, it is expensive to treat because of the serious nature of the disease and the continued presence of virus in the environment, vaccination is highly recommended for all kittens. Cats vaccinated at 6 month or older with either killed or MLV vaccine will produce an immunity good for life. Adult cats do NOT need this vaccine.

Feline Calicivirus/Herpesvirus Vaccine.
Responsible for 80-90% of infectious feline upper respiratory tract diseases. The currently available injectable vaccines will minimize the severity of upper respiratory infections, although none will prevent disease in all situations.

Intranasal vaccines are more effective at preventing the disease entirely. Don't worry about normal sneezing for a couple of days. Because intranasal vaccines produce an immunity of shorter durations, annual vaccination is recommended.

VACCINES NOT RECOMMENDED

Chlamydia or pneumonitis.
The vaccine produces on a short (2 month) duration of immunity and accounts for less than 5% of upper respiratory infections in cats. The risks outweigh the benefits.

Feline Infectious Peritonitis.
A controversial vaccine. Most kittens that contract FIP become infected during the first 3 months of life. The vaccine is labeled for use at 16 weeks. All 27 vet schools do not recommend the vaccine.

Bordetella
A new vaccine for feline bordetella has been introduced. Dr. Wolfe of Texas A&M says that bordetella is a normal flora and does not cause disease in adult cats. Dr. Lappin of Colorado State says that a review of the Colorado State medical records reveals not one case diagnosed in 10 years.

NEW DEVELOPMENTS
Giardia is the most common intestinal parasite of humans in North America, 30% or more of all dogs & cats are infected with giardia. It has now been demonstrated that humans can transmit giardia to dogs & cats & vice versa.

Heartworm preventative must be given year-round in Houston.

VACCINES BADLY NEEDED
New vaccines in development include:
Feline Immunodeficiency Virus and cat scratch fever vaccine for cats and Ehrlichia [one of the other tick diseases, much worse than Lymes] for dogs.

THE VIEW FROM THE TRENCHES; BUSINESS ASPECTS

Most vets recommend annual boosters and most kennel operators require them. For years the pricing structure of vets has misled clients into thinking that the inherent value of an annual office visit was in the "shots" they failed to emphasize the importance of a physical exam for early detection of treatable diseases. It is my hope that you will continue to require rabies & Kennel cough and emphasize the importance of a recent vet exam. I also hope you will accept the new protocols and honor these pets as currently vaccinated. Those in the boarding business who will honor the new vaccine protocols can gain new customers who were turned away from vet owned boarding facilities reluctant to change.

CONCLUSION
Dogs & cats no longer need to be vaccinated against distemper, parvo, & feline leukemia every year. Once the initial series of puppy or kitten vaccinations and first annual vaccinations are completed, immunity from MLV vaccines persists for life. It has been shown that cats over 1 year of age are immune to Feline Leukemia whether they have been vaccinated or not. Imagine the money you will save, not to mention less risks from side effects. PCR rabies vaccine, because it is not adjuvanted, will mean less risk of mediated hemolytic anemia and allergic reactions are reduced by less frequent use of vaccines as well as by avoiding unnecessary vaccines such as K-9 Corona virus and chlamydia for cats, as well as ineffective vaccines such as Leptospirosis and FIP. Intranasal vaccine for Rhiotracheitis and Calici virus, two upper respiratory viruses of cats provide more complete protection than injectable vaccines with less risk of serious reactions.

The AAHA and all 27 veterinary schools of North America are our biggest endorsement for these new protocols.

Many thanks Tenderfoot. I'll definitely be printing and filing this for future reference. I find it shocking that they would even factor in 'loss of income', particularly since people are spending astronomical amounts for other procedures. Get a grip, vets.

I agree with you badger. It is scary and disappointing how medicine, both veterinary and human, are directed by finances. Also one of the factors has been the drug companies. In order to do the testing on the vaccines to see how long they last, large amounts of money is required. Usually this is taken care of by the drug companies. However in this case, none of the drug companies want to prove that you need less of their product.

In defense of most of the veterinarians I know that wrestle with vaccine issues, the 'revenue' discussion has not much to do with the vaccine revenue but the medicine which is generated from yearly examinations. Putting this another way - if pets only came in when the owners thought the pet was sick, we would save and help a lot LESS pets. So often pets come in for a simple vaccine and we diagnose a painful ear infection or head off a crisis by early detection of diabetes. Often clients come in proud of their overweight, always thirsty, always hungry 13 year old pet and are shocked that these are signs of a problem like Cushings.

A few movements have tried to re-educate the public in the importance of examinations yearly and reducing or eliminating vaccines. I took part in a "Think Twice for Life" program - which included two physical examinations per year with all vaccines free. That is the owners would pay for two examinations and could have as many or as little vaccines as they wanted for the year. It would actually save the clients money. The program was discontinued early - lack of owner interest.

My hospitals would happy survive financially if we never gave another vaccine. The issue for the veterinary community is how to reduce the vaccines without the client visits - not for revenue sake but because so many problems and diseases are often unseen by the most diligent of owners.

AAHA is the organization that is leading the protocols with vaccines. State veterinary board and the AVMA stay away from making any direct stands on these issues; so AAHA is the main source to go to.

Here is a link to their 2006 canine protocols

Here is a link to their list of protocols. The dental protocols are also interesting to read!
http://www.aahanet.org/About_aaha/About_Position.html

I am looking forward to their next update! My hospitals vaccine protocols have been changing about every 4-6 months based on AAHA and other current studies and trends. Each protocol turnover has involved cutting vaccines down in frequency, rarely more.

I am glad that there is a site like this pets.ca and i wish more clients would read these posts;.

Ummm I've obviously missed something...

I'm lost...

Someone want to explain in layman's terms what's going on? O.o
