There's lots of current research about over vaccinating these
days, my opinion is that three vaccinations before a year of age are plenty
four at the most before one-year age!
Overdoing vaccinations can start a dog down a long road of autoimmune
problems in the future, from allergies to organ failure over vaccinating a
young dog can be bad and start expensive relationships with vet in the
future. Many Vet's like to bring
your dog into the office as much as possible vaccination protocols are one of
those ways.... I Vaccinate once every three years with the rabies shot and as
soon as vaccination laws and rabies change to five years I am sure once every five
years will work great too!

World-renowned veterinary research
scientist, Dr. W. Jean Dodds, and I have established The Rabies Challenge
Fund to raise
funds to conduct concurrent 5 and 7 year canine rabies vaccine
challenge studies in the United States. (Results of Michel AubertÕs challenge
study published in 1992 demonstrated that dogs were immune to a rabies
challenge 5 years after vaccination and Dr. Ronald SchultzÕs serological studies
have shown that dogs have antibody titer counts at levels known to confer
immunity 7 years after vaccination for rabies.) Dr. Dodds is trustee of the
fund and we are in the process of submitting IRS documentation for tax-exempt
501 (c) 3 status. For more information on the fund, read Aaron Miller's Lincoln County

owners adequate information so they do not inadvertently overvaccinate
their animals, the Nation's First legislation which would have required
veterinarians to provide vaccine disclosure forms to pet owners BEFORE they
vaccinate their animals (cats
& dogs) was
filed in Maine this year. The bill, LD 429, An Act to Require
Veterinarians to Provide Vaccine Disclosure Forms (http://www.mainelegislature.org/legis/bills/billtexts/LD042901-1.asp http://www.dogsadversereactions.com/vaccines.html )
had been introduced on my behalf by Representative Peter Rines of Wiscasset and
was vigorously opposed by the Maine Veterinary Medical Association and its
members at the public hearing on February 28th and was recently defeated by
Maine's Legislature. Pet owners in CT, PA, FL, MO, MN, RI, WI
and TX are working on getting similar bills filed in their states for next
year's legislative sessions, and AB263 was introduced in Nevada this year

Texas
State Board of Veterinary Medical Examiners
November
2005 Board Notes
In
February 2003, the Board adopted AN OPEN LETTER TO VETERINARIANS RE:
VACCINATION PROTOCOLS. In the LETTER, the Board noted that many aspects
of veterinary practice were evolving quickly, including the area of vaccination
protocols Ð vaccination intervals, duration of immunity, risks of vaccination,
and the efficacy of certain vaccines that are routinely used by many
Veterinarians. Recent studies have cast new light on these issues,
prompting organizations such as the American Veterinary Medical Association,
American Association of Feline Practitioners, and American Animal Hospital
Association, to issue reports suggesting a need to revise some commonly
accepted practices.
While
the Board has stated that it does not intend to Òmicro manageÓ the practice of
veterinarians in this area, it did recommend that veterinarians keep informed
of the latest developments in vaccines and vaccinations; communicate with
clients the benefits and risks associated with the administration of any given
vaccine; and seek the clientÕs consent to the vaccinations offered. The
Board followed up with a reminder in the November 2004 Board Notes, again urging Veterinarians to review
their vaccination protocols. The Board noted that mere adherence to
custom may, in some cases, be insufficient to meet the evolving standard of
care for administering various vaccines. For example, coronavirus
vaccines are still being routinely prescribed for dogs and cats by some
veterinarians, although recently published positions of the veterinary associations
unanimously do not recommend them.
The
Board believes that veterinarians are becoming aware of the vaccination issues
and changes are being made. Some are beginning to discuss with their
clients the concept of ÒcoreÓ versus Ònon-coreÓ vaccines. Clients are
also becoming better informed on vaccination issues. One area that is
still of concern is that of informed consent. Indications are that not
enough is being done to inform the client of the need for the offered vaccines
and the securing of informed consent. This simply involves a veterinarian
providing enough information about the vaccines to the client so that he or she
can give a reasoned consent to the recommended vaccines. This, in turn,
requires a discussion of risks versus benefits of vaccination on a pet-by-pet
basis. The benefits of certain vaccines, for example, distemper and
parvovirus, are well known health threats and do not require detailed
explanation, while a vaccine for Lyme Disease, where risk is not the same in
all locations, may need more explanation. Options to a vaccine may be
available. Less frequent vaccinations may provide the necessary
protection in many cases.
Once
the risks and benefits of the vaccines have been explained to a client, the
veterinarian should seek the clientÕs consent for the recommended
vaccines. A written Òauthorization to vaccinateÓ is recommended, but if a
written authorization is not used, the patient record should be carefully noted
to show that the client approved the vaccines after an explanation of benefits
and risks. Examples of model consent forms are now widely available.
Informed
consent is not a new concept in veterinary medicine. Veterinarians
routinely seek consent for treatments for their patients. The Board believes that informed consent
should become the standard for vaccination protocols as well.
Veterinarians are urged to consider this matter with the goal in mind of
improving veterinary services for all their patients.

State
Recommends Veterinarians Provide Vaccine Disclosure
by
Aaron Miller
AUGUSTA -- A state committee recently encouraged Maine veterinarians to inform
pet owners of the recommended interval for administering vaccines.
Senate Chair Sen. John Nutting and House Chair Rep. John Piotti wrote to the
Maine Veterinary Medical Association President Matt Townsend earlier this
month, asking veterinarians to provide pet owners with that information.
The association consists of Maine veterinarians and volunteers and represents
over 90 percent of veterinarians in Maine.
The June 3 letter came after the state's Committee on Agriculture, Conservation
and Forestry voted Wiscasset Rep. Peter Rines' proposed legislation requiring
veterinarians to provide vaccine disclosure forms ought not to pass.
The Maine Veterinary Medical Association opposed Rines' LD 429, a bill that
would require a veterinarian to provide a vaccine disclosure form to the owner
of a cat or dog before vaccinating those animals. The proposal came after
Kris Christine, of Alna, said she inadvertently learned her veterinarian
administered a vaccination her pet did not need.
The vaccine disclosure is aimed at releasing information regarding proven or
demonstrated durations of immunity as well as advantages and disadvantages of
vaccines.
"We strongly encourage Maine veterinarians to inform pet owners of the
recommended interval for administering a vaccine and potential risks associated
with that vaccine," Nutting and Piotti wrote. "We realize that immunology
is not a static field and the science is complex. We do not propose to
dictate the detail of information provided. We do, however, want to
emphasize the importance of information being available at veterinarian's
offices."
Nutting and Piotti requested the Maine Veterinary Medical Association apprise
the Committee on Agriculture, Conservation and Forestry of any materials or
guidelines developed by the association in regard to the committee's request.
"We would like to know the extent to which these guidelines or materials
are being incorporated in your members' veterinary practices," Nutting and
Piotti wrote.
In an interview June 14, Townsend said that the Maine Veterinary Medical
Association is not opposed to the committee's request. Townsend added
that the veterinary association is currently in the process of including
information about vaccines on the association's website. Different
opinions on vaccinations and protocols are planned to be posted, he said.
"We have never been opposed to the legislature saying we'd like for you to
offer some type of pamphlet," Townsend said. "But we have
questions about what pamphlets we should use."
The committee does not make any recommendation in the June 3 letter.
"I don't think a pamphlet is the one answer or the best answer,"
Townsend said. "It is a step that can be quite helpful for a lot of
clinics. The whole concept we are in favor of."
Although pleased with the committee's request, Christine remains skeptical.
"I personally don't believe a majority of veterinarians will provide
disclosure," Christine said. "I think it will be necessary for
the committee to introduce the bill in December."
If veterinarians refuse to disclose vaccine information, Christine recommended
pet owners contact their representatives.
"Pet owners are entitled to full disclosure," Christine said.
"They deserve to know how long these vaccines have been proven for
immunity."

The following are quotes from the article
that I found especially interesting and once again illustrates
why Representative Rines' LD 429, An Act to Require Veterinarians to
Provide Vaccine Disclosure Forms is so important to pet owners -- they
simply will not have access to this information otherwise.

Regards, Kris Christine
ÒI have studies that show duration of
immunity at seven to nine years for all the core vaccines except rabies, and
even on an antibody basis I can show that rabies gives much longer protection
than three years,Ó says Dr. Schultz.
Although AAHA recommends vaccinating
against distemper every three years after the initial puppy shots, challenge
studies have shown that the minimum duration of immunity can last five to seven
years, and perhaps even longer. In fact, titers have indicated that dogs can be
protected for nine to 15 years. ÒTo be honest, although canine distemper is a
core vaccine, I think a dog only needs to receive it once in his life,Ó says
Dr. Schultz. ÒThe same goes for canine parvo and adenovirus-2. ThatÕs the
vaccination program IÕve been practicing on my own dogs without any difficulty
whatsoever. WeÕve never had a vaccine-preventable disease occur.Ó
"challenge
studies indicate that a vaccinated kitten can remain protected from feline
parvo for eight years."

Vaccination:
Which ones do
they REALLY NEED, and HOW OFTEN?
by
Ann Brightman
When
Helena took her new Sheltie puppy, Mick, to the vet for his first check-up, she
felt more than a little anxious when it came time for him to receive his shots.
While she wanted to protect her new friend from deadly diseases like distemper
and parvo, she was also concerned about the health risks associated with
over-vaccination. Although Helena went ahead with the vaccines and follow-up
boosters, she was worried about subjecting Mick to subsequent annual shots,
even though her vet told her she was risking her dogÕs health even more by not
doing so.
ItÕs a common quandary these days,
especially as we hear more and more about the often devastating side effects of
over-vaccination. How do we prevent our dogs or cats from contracting
infectious diseases that can often be fatal, while also protecting them from
the equally serious health consequences of too many shots? The best strategy is
to learn which vaccines are absolutely necessary (referred to as core
vaccines), why theyÕre needed, and what the minimum requirements are for each
to ensure protection from disease without over-vaccinating.
WHAT
ARE CORE VACCINES?
ÒCore vaccines are those that every dog
or cat should receive, regardless of geographic location or lifestyle,Ó says
Dr. Ron Schultz, Professor and Chair of the Department of Pathological Studies
at the University of Wisconsin-MadisonÕs School of Veterinary Medicine. For
dogs, the four core vaccines are canine distemper (CDV), canine parvovirus-2
(CPV-2), canine adenovirus-2 (CAV-2) and rabies. Those for cats are feline
panleukopenia or parvovirus (FPV), feline herpesvirus-1 (FHV-1), also referred
to as feline viral rhinotracheitis, feline calicivirus (FCV) and rabies. In
this article, the first in a three-part series, weÕll be taking a close-up look
at canine distemper, feline panleukopenia and rabies.
The eight vaccinations listed above are
considered core because the diseases they protect against are distributed over
a wide area and have a high mortality rate. ÒThese vaccinations are absolutely
necessary,Ó says Dr. Schultz. ÒYou want the vaccine to be the first antigens to
prime the immune system. You donÕt want to leave it up to natural immunization or
exposure.Ó This is because, when compared to the actual disease-causing virus,
the vaccine is a safer way to protect the animal. ÒIf the vaccine is live, itÕs
attenuated. If itÕs killed, it canÕt cause disease,Ó explains Dr. Schultz.
ÒItÕs true that many puppies that never see a vet get naturally immunized by
exposure to distemper, as an example, but for every one that gets vaccinated,
probably another would have died if the first encounter with distemper occurred
prior to vaccination.Ó
MINIMIZING
VACCINATION
Although core vaccines are necessary to
protect your companion from infectious disease, even these do not need to be
given on an annual basis. ÒThatÕs what weÕre trying to change,Ó says Dr.
Schultz. ÒWhat we recommend is that both puppies and kittens get the core
vaccines at least once at or over the age of 12 weeks.Ó The 12 weeks is
significant, because prior to that, many animals still have passive maternal
antibodies that block immunization, which means they may not respond to the
vaccine and are therefore unprotected against the disease. American Association
Hospital Association (AAHA) guidelines recommend vaccinating again at one year,
and once every three years after that, although even that may not be necessary. ÒI have studies that show duration of
immunity at seven to nine years for all the core vaccines except rabies, and
even on an antibody basis I can show that rabies gives much longer protection
than three years,Ó says Dr. Schultz.
CANINE DISTEMPER (CDV)
CDV is a highly infectious and often
fatal disease that attacks the respiratory, gastrointestinal and central
nervous systems. Although dogs of any age can contract distemper, puppies up to
six months of age are most susceptible to the disease, which
can cause a range of symptoms from fever,
loss of appetite and eye inflammation in its early stages, to diarrhea,
vomiting, pneumonia, and neurological complications such as ataxia, seizures
and paralysis.
Canine distemper occurs around the world
not only among domesticated dogs, but also in many wild carnivores such as
raccoons, skunks and foxes. ÒWildlife is actually now more of a reservoir for
distemper than dogs are,Ó says Dr. Schultz. ÒThe virus is spread mainly by air,
or by direct contact with secretions from the infected animal. The mortality
rate among puppies with distemper is 50% or higher.Ó On the plus side, the
distemper virus is very fragile and easily destroyed by outside influences. ÒIt
doesnÕt live very long in the environment,Ó says Dr. Schultz. ÒIt dies very
quickly because it is what we call an enveloped virus. These kinds of viruses
are highly susceptible to water, disinfectant and sunlight.Ó
Although there is only one distemper
serotype, there are several genotypes. ÒWhat this means is that, from an
immunologic standpoint, it doesnÕt matter which distemper infects the animal,
theyÕre all similar; the vaccine for canine distemper can protect against the
different genotypes.Ó Dr. Schultz adds that modified live vaccines (MLV) are
most effective for distemper. ÒIn fact thereÕs no question in my mind that you
should be using live vaccines for most of the cores. Although attenuated, live
vaccines infect and replicate, and thatÕs how you get immunity.Ó
Although
AAHA recommends vaccinating against distemper every three years after the
initial puppy shots, challenge studies have shown that the minimum duration of
immunity can last five to seven years, and perhaps even longer. In fact, titers
have indicated that dogs can be protected for nine to 15 years. ÒTo be honest,
although canine distemper is a core vaccine, I think a dog only needs to
receive it once in his life,Ó says Dr. Schultz. ÒThe same goes for canine parvo
and adenovirus-2. ThatÕs the vaccination program IÕve been practicing on my own
dogs without any difficulty whatsoever. WeÕve never had a vaccine-preventable
disease occur.Ó
Titer testing is highly effective for
canine distemper, but according to Dr. Schultz, the best time to do it is at
two weeks or more after the last puppy vaccination, to ensure that the animal
responded to its initial vaccines. ÒTo my mind, thatÕs the only time itÕs of
medical benefit to use a titer test for canine distemper. After that, you donÕt
really need to titer the animal since you can easily go five or seven years
before the next vaccine.Ó
FELINE
PANLEUKOPENIA (FPV)
Although FPV is sometimes referred to as
feline distemper, this terminology is misleading. ÒWhen I talk about feline
Ôdistemper,Õ I always talk about it as feline parvo or panleukopenia,Ó explains
Dr. Schultz. ÒThe virus that causes this disease is essentially
identical to the canine parvo virus, but
not the canine distemper virus. If a dog has parvo, it can infect a cat, but
this doesnÕt happen with distemper.Ó
Most often found in kittens, FPV is a
contagious and deadly disease that attacks and destroys growing cells in the
intestine, blood and nervous system. It causes diarrhea, vomiting, a lowered
white blood cell count, and neurological symptoms such as tremors. Kittens up
to six months of age can easily die from the disease, while older cats may
develop much milder signs. ÒThereÕs a tremendous age-related resistance to
parvo,Ó says Dr. Schultz. ÒIf the animal is less than a year old, mortality is
80% to 100%. However, I rarely see mortality in animals over a year of age,
although I might see mild morbidity. Nevertheless, feline parvo is the one cat
vaccin4e I absolutely insist on.Ó
Like canine distemper, feline parvo has
worldwide distribution with outbreaks occurring most commonly in urban areas
during the summer months. The disease is transmitted by direct contact,
although cats can also contract FPV from the fecal matter of an infected
feline. Unlike canine distemper, the parvo virus is extremely long-lived, and
can remain active in the environment for months or even longer. ÒParvo is what
we call a naked virus and is one of the most resistant,Ó says Dr. Schultz. Soil
contaminated with the parvo virus still has the ability to infect an animal a
year later. ÒIn fact, parvo is more often caused by environmental contamination
than direct contact with an infected animal. You donÕt need the infected cat to
be in the environment for very long in order for it to leave the virus behind.Ó
As with canine distemper, MLV vaccines
are very effective for preventing feline panleukopenia. ÒWith parvo, in fact,
youÕd better be using live vaccines, because the killeds donÕt work.Ó As with
other core vaccines, kittens should be vaccinated at 12 weeks. Titer testing is
very effective for this disease, although challenge
studies indicate that a vaccinated kitten can remain protected from feline
parvo for eight years.
RABIES
(RV)
Unlike distemper and parvo, rabies is a
disease that can be transmitted from animals to humans, which is why rabies
vaccinations are required by law throughout North America. The virus infects
the central nervous system, causing encephalitis and death. Symptoms can
include confusion, partial paralysis, aggressive behavior, excessive salivation
and other neurological signs. Although rabies occurs worldwide, including in
Asia, Africa and Latin America, some countries such as the U.K. are
rabies-free. In North America, rabies is most prevalent in the eastern portions
of the continent, although cases can occur anywhere. Wild animals such as
raccoons, skunks, bats and foxes are the major carriers. Because rabies isnÕt
age-related, mammals at all stages of life can be affected with the same degree
of severity. The chief means of transmission is by a bite from an infected
animal.
ÒThere are multiple strains of rabies,
but the important thing is that the vaccine prevents infection with all those
different strains,Ó says Dr. Schultz. ÒAlthough the risk of infection in
domesticated animals is generally low, the public health concern is the issue.
ThatÕs what drives the regulations for rabies vaccines.Ó As with the other core
vaccines, puppies and kittens should be vaccinated at 12 weeks. Although some
states and provinces have approved a three-year rabies vaccine, some still
require annual re-vaccination for dogs and cats, even though the duration of
immunity based on challenge studies has been shown to be three to seven years.
ÒThe regulations vary from state to state and province to province, and even
from municipality to municipality.Ó ItÕs also important to realize that a
municipality might have a more restrictive requirement than the state or
province itÕs a part of, although not the other way around.
ÒRabies titers are effective, but
thereÕs no point running them because youÕre going to have to vaccinate your
animal by law anyhow,Ó says Dr. Schultz. However, titer testing for rabies is
useful in cases where the animal has had an adverse reaction to the vaccine, or
has a medical condition that could be aggravated by the vaccination. ÒIn these
situations, local municipalities will sometimes accept a letter from the vet as
a reason not to vaccinate every three years, But the guardian has to understand
that the animal is still considered to be non-vaccinated, and if it bit
someone, it would be treated as such if itÕs gone beyond the three years,
irrespective of the vetÕs letter. Even so, if you have a dog that for health
reasons
shouldnÕt be given a rabies vaccine,
itÕs better to take the chance of it being quarantined for biting someone than
to give the vaccine and kill the dog.Ó
BACK
TO BASICS
Vaccinations definitely have their place
in disease prevention, but knowing where to draw the line is key. ÒIÕve seen it
go from no vaccines back in the mid-1960s, to where we just kept adding one
after the other,Ó says Dr. Schultz. The pendulum has since started swinging
back again as organizations such as AAHA and American Association of Feline
Practitioners (AAFP) began looking more closely at which vaccines out of the 12
for cats and 16 for dogs were really needed and why. ÒWe used to have one
manufacturer that made a canine vaccine combo with 13 different components in
it. ThatÕs not good, and thatÕs why itÕs not available anymore.Ó Now, by contrast,
companies are coming out with information demonstrating that their products
give duration of immunity lasting several years. ÒAll the major manufacturers
are coming on board and saying that their core vaccines give at least three
years immunity. To me, thatÕs the greatest gratification in the more than 25
years IÕve been doing this.Ó

Too many shots?
By
Bonnie Washuk, Staff Writer
Sunday, February 20,2005
Ashleigh
D. Starke/Sun Journal
CANINE
CONCERNS: Kris Christine of Alna hopes the Legislature will pass legislation
requiring all Maine veterinarians to give pet owners disclosure forms on the
pros and cons of vaccinations. In January 2003, her Labrador retriever, Meadow,
pictured here, developed a mast cell tumor on the site of a rabies vaccination.
AUGUSTA
- Like many pet owners, when Kris Christine of Alna got cards from her veterinarian
reminding her that Meadow's and Butter's shots were due, she brought in her
lovable Labs.
Her vet recommended that her pets have
rabies shots every other year and distemper shots every year, Christine said.
But months after Meadow's biannual rabies
shot in the fall of 2003, she noticed something. "He had this weird thing
on his back hind side," she said. "Every time he'd run, it would
swell, then it would go away."
Meadow eventually was diagnosed with
mast cell cancer, which Christine believes resulted from the vaccination
injection at that same spot on his leg. "It's not something you
want," she said. "It's an aggressive cancer."
Veterinarians say the likelihood is very
small that Meadow's cancer stemmed from the shot. However, while taking care of
Meadow's cancer, Christine stumbled on a hot debate in the animal health field:
How often should dogs and cats be vaccinated?
While experts stress that vaccines are
vital to the health of pets, mounting research indicates vaccines can no longer
be considered harmless. Research shows they can cause adverse health effects -
everything from lower immunity against viruses, bacteria and parasites, to
cancer - and that some vaccines do not have to be given as frequently as once
thought.
In response, the American Animal
Hospital Association in 2003 began recommending less frequent vaccinations for
cats and dogs.
Christine, who began researching the
subject after Meadow's cancer was detected, quickly became an energetic
crusader, spreading information about vaccinations and questioning frequency
guidelines. She believes that by following her veterinarian's recommendations,
"Meadow was being over-vaccinated for years."

Christine of Alna hopes the Legislature will pass legislation requiring all
Maine veterinarians to give pet owners disclosure forms on the pros and cons of
vaccinations.
In
the process, Christine said she discovered that Maine law required a rabies
shot for dogs and cats every two years, despite the fact that the vaccine's
manufacturer says it is good for three.
She questioned the law in early 2004,
and it was changed last fall, according to state public health veterinarian Dr.
Robert Gholson. The state now mandates that rabies shots be given every three
years. (Saying not all veterinarians have gotten the word, Gholson is sending
out a second reminder.)
Christine now hopes she will be equally
successful with her next effort: to get the Legislature to pass a law requiring
Maine veterinarians to disclose the pros and cons of vaccines.
Rep. Peter Rines, D-Wiscasset, is
sponsoring L.D. 429, and said that since introducing the bill, the outpouring
of e-mails and letters in favor has been overwhelming.
"In my tenure as a legislator I've
never had this kind of response," he said. Pet owners are thanking him,
and some people outside Maine have said they hope his bill will lead to similar
laws in other states, he said.
"Everyone wants to do the best
thing for our four-legged friends," said Rines, noting his bill is
intended only to give consumers information.
But some Maine veterinarians plan to
voice their opposition to the bill at its public hearing on Feb. 28. Saying
they feel like they're under attack, the opponents say they see no need for
disclosure forms.
The
making of a crusader
After
Meadow was diagnosed with cancer last year, he underwent two operations. A
chunk of his back thigh was removed.
On the bottom of one of Christine's
veterinarian bills in April for cancer treatment was a reminder that Meadow's
distemper shot was due in November and his next rabies shot in 2005.
It upset Christine. "I said, 'He's
not going to be alive then.'"
Christine said her veterinarian said the
cancer did not come from the vaccine, but Christine was skeptical. She grew
even more doubtful after learning that the law required dog immunizations every
two years even though the rabies vaccine lasted three.
When she got the bill, Christine told
her vet she had a problem giving her dog vaccinations every year or every other
year.
"Here's my dog lying at my feet,
suffering with a huge chunk of his hind leg removed. I thought, 'You were
giving him medication that you know he doesn't need.'"
Christine found a new veterinarian and
became an advocate for changing the laws and making pet owners more aware of
the potential health risks posed by vaccinations. "We need the
tools," she said
She is not the only one who feels that
way.
Among those concerned about pets receiving
vaccinations too frequently are AKC judge and former breeder Arnold Woolf of
Lewiston and Larry Doyon of Munster Abbey Kennels in Minot, breeders of German
shepherds. Both say they support the legislation.
Experts:
Risks are low, but . . .
Christine's
efforts have also met angry opposition. Last week the Maine Veterinary Medical
Association came out against L.D. 429. In a Feb. 2 letter to lawmakers, MVMA
President Matt Townsend did not directly spell out why the organization is
opposed to the bill.
But Townsend complained that such a law
would mandate "cumbersome disclosure and consent procedures for every
vaccination and medication dispensed by veterinarians." It also said
Christine "has launched what can only be described as an aggressive scare
campaign, designed to drive a wedge of distrust between pet owners and their
veterinarians."
Actually, the law makes no mention of
medication other than vaccines. The law says veterinarians must provide
disclosure forms informing consumers about the advantages and disadvantages of
vaccines.
MVMA Executive Director Bill Bell said
there is no Maine protocol on how often vaccines should be administered, and
that even top researchers disagree. "The bill is vague to the point of
being ridiculous," he said.
Veterinarians are worried a disclosure
form would scare away some pet owners from having their dogs and cats
vaccinated, which would lead to diseases coming back, Bell said. He added that
the bill will increase paperwork for veterinarians without doing any good.
One nationally recognized vaccine
researcher, Dr. Ronald Schultz, favors the law.
While rare, vaccines can cause adverse
health affects in cats and dogs, said Schultz, an expert in animal vaccinations
and chair of the department of pathobiological sciences at the University of
Wisconsin School of Veterinary Medicine.
"I favor anything that would better
inform the potential buyer of what they need and what they're getting," he
said in a telephone interview from his Wisconsin office.
A majority of veterinarians are already
providing that information, but some are not, he said.
The thinking that vaccines are harmless
is changing, Schultz said, adding that annual vaccinations don't help pets, and
can hurt them. "For years we worked under a philosophy of 'if it doesn't
help, (at least) it won't hurt.'"
What he called "an awakening"
began in the 1980s when healthy cats given vaccines were getting cancer.
"The odds were small, but if the odds are 1 in 1,000 that doesn't matter
if it's your pet," he said.
The probability of dog vaccines causing
cancer is lower than cats, he said. "But we're constantly learning. The
wake-up call to the veterinarian profession was that vaccines create a risk.
... No matter how rare the adverse effects are, we don't want to give a product
that's not needed."
Schultz said the veterinary profession
has been using annual or biannual shots as a way to bring clients through the
door for the more important exam. Convincing pet owners to come in by telling
them their pets' annual or biannual shots are due should no longer be
practiced, he said.
Schultz cited the newest guidelines from
the American Animal Hospital Association, which in 2003 went from recommending
annual distemper shots to one every three years. Under the guidelines, dogs and
cats should receive core shots for rabies and distemper beginning at 12 weeks,
a booster at one year, then boosters no more frequently than every three years.
(Some central and western Maine veterinarians are following the
recommendations, others are not. See related chart.)
All other vaccines are "optional," according to Schultz and the AAHA, and are based on the animal's lifestyle and risk. For instance, annual Lyme disease and
