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
skeptics.
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
mothers 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.
