Science of Vaccine Damage
by Catherine O’Driscoll
team at Purdue University School of
Medicine conducted several studies (1,2)
determine if vaccines can cause changes
immune system of dogs that might lead to life-threat-
ening immune-mediated diseases. They obviously
conducted this research because concern already
existed. It was sponsored by the Haywood Founda-
tion which itself was looking for evidence that such
changes in the human immune system might also be
vaccine induced. It found the evidence.
The vaccinated, but not the non-vaccinated, dogs in the Purdue studies
developed autoantibodies to many of their own biochemicals, including
fibronectin, laminin, DNA,
albumin, cytochrome C, cardiolipin and collagen.
This means that the vaccinated dogs -- ”but not the non-vaccinated
dogs”-- were attacking their own fibronectin, which is involved in
tissue repair, cell multiplication and growth, and differentiation
between tissues and organs in a living organism.
The vaccinated Purdue dogs also developed autoantibodies
to laminin, which is involved in many cellular activities including the
adhesion, spreading, differentiation,
proliferation and movement of cells. Vaccines thus appear to be capable
of removing the natural intelligence of cells.
Autoantibodies to cardiolipin are frequently found in patients with the
serious disease systemic lupus erythematosus and also in individuals
with other autoimmune diseases. The presence of elevated
anti-cardiolipin antibodies is significantly associated with clots
within the heart or blood vessels, in poor blood clotting, haemorrhage,
bleeding into the skin, foetal loss and neurological conditions.
The Purdue studies also found that vaccinated dogs were developing
autoantibodies to their own collagen. About one quarter of all the
protein in the body is collagen. Collagen provides structure to our
bodies, protecting and supporting the softer tissues and connecting
them with the skeleton. It is no wonder that Canine
Health Concern’s 1997 study of
4,000 dogs showed a high number of dogs developing mobility problems
shortly after they were vaccinated
(noted in my 1997 book, What Vets Don’t Tell You About Vaccines).
Perhaps most worryingly, the Purdue studies found that the vaccinated
dogs had developed autoantibodies to their
own DNA. Did the alarm bells sound? Did the scientific community call a
halt to the vaccination program? No. Instead, they stuck their fingers
in the air, saying more research is needed to ascertain whether
vaccines can cause genetic damage. Meanwhile, the study dogs were found
good homes, but no long-term follow-up has been conducted. At around
the same time, the American Veterinary Medical Association (AVMA)
Vaccine-Associated Feline Sarcoma Task Force initiated several studies
to find out why
160,000 cats each year in the USA develop terminal cancer at their
vaccine injection sites.(3) The fact that cats can get vaccine-induced
cancer has been acknowledged by veterinary bodies around the world, and
even the British Government acknowledged
it through its Working Group charged with the task of looking into
canine and feline vaccines(4) following pressure from Canine Health
Concern. What do you imagine was the advice of the AVMA Task Force,
veterinary bodies and governments? “Carry on vaccinating until we find
out why vaccines are killing cats, and which cats are most likely to
In America, in an attempt to mitigate the problem,
they’re vaccinating cats in the tail or leg so they can amputate when
cancer appears. Great advice if it’s not your cat amongst the hundreds
of thousands on the “oops” list.
But other species are okay - right? Wrong. In August 2003, the Journal
of Veterinary Medicine carried an Italian study which showed that dogs
also develop vaccine-induced cancers at their injection sites.(5) We
already know that vaccine-site cancer is a possible sequel to human
vaccines, too, since the Salk polio vaccine was said to carry a monkey
retrovirus (from cultivating the vaccine on monkey organs) that
produces inheritable cancer. The monkey retrovirus SV40 keeps turning
up in human cancer sites.
It is also widely acknowledged that vaccines can cause a fast-acting,
usually fatal, disease called autoimmune haemolytic anaemia (AIHA).
Without treatment, and frequently with treatment, individuals
can die in agony within a matter of days. Merck, itself a multinational
vaccine manufacturer, states in The Merck Manual of Diagnosis and
Therapy that autoimmune haemolytic anaemia may be caused by modified
live-virus vaccines, as do Tizard’s Veterinary Immunology (4th edition)
and the Journal of Veterinary
Internal Medicine. (6) The British Government’s Working Group, despite
being staffed by vaccine-industry consultants who say they are
independent, also acknowledged this fact. However, no one warns the pet
owners before their animals are subjected to an unnecessary booster,
and very few owners are told why after their pets die of AIHA.
A Wide Range of Vaccine-induced
We also found some worrying correlations between vaccine events and the
onset of arthritis in our 1997 survey. Our concerns were compounded by
research in the human field.
The New England Journal of Medicine, for example, reported that it is
possible to isolate the rubella virus from affected joints in children
vaccinated against rubella. It also told of the isolation of viruses
peripheral blood of women with prolonged arthritis following
Then, in 2000, CHC’s findings were confirmed by research which showed
that polyarthritis and other diseases like amyloidosis, which affects
organs in dogs, were linked to the combined vaccine given to dogs.(8)
There is a huge body of research, despite the paucity of funding from
the vaccine industry, to confirm that vaccines can cause a wide range
of brain and central nervous system damage. Merck itself states in its
Manual that vaccines (i.e., its own products) can cause encephalitis:
brain inflammation/ damage. In some cases, encephalitis involves
lesions in the brain and
throughout the central nervous system. Merck states that “examples are
the encephalitides following measles, chickenpox, rubella, smallpox
vaccination, vaccinia, and many other less well defined viral
When the dog owners who took part in the CHC survey reported that their
dogs developed short attention spans, 73.1% of the dogs did so within
three months of a vaccine event. The same percentage
of dogs was diagnosed with epilepsy within three months of a shot (but
usually within days). We also found that 72.5% of dogs that were
considered by their owners to be nervous and of a worrying disposition,
first exhibited these traits within the three-month post-vaccination
I would like to add for the sake of Oliver, my friend who suffered from
paralysed rear legs and death shortly after a vaccine shot, that
“paresis” is listed in Merck’s Manual as a symptom of encephalitis.
This is defined as muscular weakness of a neural (brain) origin which
involves partial or incomplete paralysis, resulting
from lesions at any level of the descending pathway from the brain.
Hind limb paralysis is one of the potential
consequences. Encephalitis, incidentally, is a disease that can
manifest across the scale from mild to severe and can also cause sudden
Organ failure must also be suspected when it occurs shortly after a
vaccine event. Dr Larry Glickman,
who spearheaded the Purdue research into post-vaccination biochemical
changes in dogs, wrote in a letter to Cavalier Spaniel breeder Bet
“Our ongoing studies of dogs show that following routine vaccination,
there is a significant rise in the level of
antibodies dogs produce against their own tissues. Some of these
antibodies have been shown to target the thyroid gland, connective
tissue such as that found in the valves of the heart, red blood cells,
DNA, etc. I do believe that the heart conditions in Cavalier King
Charles Spaniels could be the end result of repeated immunisations by
vaccines containing tissue culture contaminants that cause a
progressive immune response directed at connective tissue in the heart
valves. The clinical manifestations would be more pronounced in dogs
that have a genetic predisposition
[although] the findings should be generally applicable to all dogs
regardless of their breed.”
I must mention here that Dr Glickman believes that vaccines are a
necessary evil, but that safer vaccines
need to be developed.
Meanwhile, please join the queue to place your dog, cat, horse and
child on the Russian roulette wheel because a scientist says you should.
Vaccines Stimulate an Inflammatory Response
The word “allergy” is synonymous with “sensitivity” and “inflammation”.
It should, by rights, also be synonymous
with the word “vaccination”. This is what vaccines do: they sensitise
(render allergic)an individual in the process of
forcing them to develop antibodies to fight a disease threat. In other
words, as is acknowledged and accepted, as part of the vaccine process
the body will respond with
inflammation. This may be apparently temporary or it may be
Holistic doctors and veterinarians have known this for at least 100
They talk about a wide range of inflammatory or “-itis” diseases which
arise shortly after a vaccine event. Vaccines, in fact, plunge many
individuals into an allergic state. Again, this is a disorder that
ranges from mild all the way through to the suddenly fatal.
Anaphylactic shock is the culmination: it’s where an individual has a
massive allergic reaction to a vaccine
and will die within minutes if adrenaline or its equivalent is not
There are some individuals who are genetically not well placed to
withstand the vaccine challenge. These are the people (and animals are
“people”, too) who have inherited faulty B and T cell function. B and T
cells are components within the immune system which identify foreign
invaders and destroy them, and hold the invader in memory so that they
cannot cause future harm. However, where inflammatory responses are
concerned, the immune system overreacts and causes
unwanted effects such as allergies
and other inflammatory conditions.
Merck warns in its Manual that patients with, or from families with, B
and/or T cell immunodeficiencies
should not receive live-virus vaccines due to the risk of severe or
fatal infection. Elsewhere, it lists features of B and T cell
immunodeficiencies as food allergies, inhalant allergies, eczema,
neurological deterioration and heart disease. To translate, people with
these conditions can die if they receive live-virus vaccines. Their
immune systems are simply not competent enough to guarantee a healthy
reaction to the
viral assault from modified live-virus vaccines.
Modified live-virus (MLV) vaccines replicate in the patient until an
immune response is provoked. If a defence isn’t stimulated, then the
vaccine continues to replicate until it gives the patient the very
disease it was intending to prevent.
Alternatively, a deranged immune response will lead to inflammatory
conditions such as arthritis, pancreatitis, colitis, encephalitis and
any number of autoimmune diseases such as cancer and leukaemia, where
the body attacks its own cells.
A new theory, stumbled upon by Open University student Gary Smith,
explains what holistic practitioners
have been saying for a very long time. Here is what a few of the
holistic vets have said in relation to their patients:
Dr. Jean Dodds: “Many veterinarians trace the present problems with
allergic and immunologic diseases to the introduction of MLV
Christina Chambreau, DVM: “Routine vaccinations are probably the worst
thing that we do for our animals. They cause all
types of illnesses, but not directly to where we would relate them
definitely to be caused by the vaccine.” (10)
Martin Goldstein, DVM: “I think that vaccines...are leading killers of
dogs and cats in America today.”
Dr Charles E. Loops, DVM: “Homoeopathic veterinarians and other
holistic practitioners have maintained for some time that vaccinations
do more harm than they provide benefits.” (12)
Mike Kohn, DVM: “In response to this [vaccine] violation, there have
been increased autoimmune diseases (allergies being one component),
epilepsy, neoplasia [tumours], as well as behavioural problems in small
A Theory on Inflammation
Gary Smith explains what observant healthcare practitioners have been
saying for a very long time, but perhaps
they’ve not understood why their observations led them to say it. His
theory, incidentally, is causing a huge stir within the inner
scientific sanctum. Some believe that his theory could lead to a cure
for many diseases including cancer. For me, it explains why the vaccine
process is inherently questionable.
Gary was learning about inflammation as part of his studies when he
struck upon a theory so extraordinary that it could have implications
for the treatment of almost every inflammatory disease -- including
Alzheimer’s, Parkinson’s, rheumatoid arthritis and even HIV and AIDS.
Gary’s theory questions the received wisdom that when a person gets
ill, the inflammation that occurs around the infected area helps it to
heal. He claims that, in reality, inflammation prevents the body from
recognizing a foreign substance and therefore serves as a hiding place
for invaders. The inflammation occurs when at-risk cells produce
receptors called All (known as
angiotensin II type I receptors). He says that while At1 has a
balancing receptor, At2, which is supposed to switch off the
inflammation, in most diseases this does not happen.
“Cancer has been described as the wound that never heals,” he says.
“All successful cancers are surrounded
by inflammation. Commonly this is thought to be the body’s reaction to
try to fight the cancer, but this is not the case.
“The inflammation is not the body trying to fight the infection. It is
actually the virus or bacteria deliberately causing inflammation in
order to hide from the immune system [author’s emphasis].” (14)
If Gary is right, then the inflammatory process so commonly stimulated
by vaccines is not, as hitherto
assumed, a necessarily acceptable sign. Instead, it could be a sign
that the viral or bacterial component,
or the adjuvant (which, containing foreign protein, is seen as an
invader by the immune system), in the vaccine is winning
by stealth. If Gary is correct in believing that the inflammatory
response is not protective but a sign that invasion is taking place
under cover of darkness, vaccines are certainly not the
friends we thought they were. They are undercover assassins working on
behalf of the enemy, and vets and medical doctors are unwittingly
acting as collaborators. Worse, we animal guardians and parents are
actually paying doctors and vets to unwittingly betray our loved ones.
Potentially, vaccines are the stealth bomb of the medical world. They
are used to catapult invaders inside the castle walls where they can
wreak havoc, with none of us any the wiser. So rather than experiencing
frank viral diseases such as the ‘flu, measles, mumps and rubella (and,
in the case of dogs, parvovirus and distemper), we are allowing the
viruses to win anyway - but with
cancer, leukaemia and other inflammatory or autoimmune (self-attacking)
taking their place.
The Final Insult
All 27 veterinary schools in North America have changed their protocols
for vaccinating dogs and cats along the following lines; (15) however,
vets in practice are reluctant to listen to these changed protocols and
veterinary bodies in the UK and other countries are ignoring the
Dogs’ and cats’ immune systems mature fully at six months. If modified
live-virus vaccine is given after six months of age, it produces
immunity, which is good for the life of the pet. If another MLV vaccine
is given a year later, the antibodies from the first vaccine neutralise
the antigens of the second vaccine and there is little or no effect.
The litre is not “boosted”, nor are more memory cells induced. Not only
are annual boosters unnecessary, but they subject
the pet to potential risks such as allergic reactions and
immune-mediated haemolytic anaemia.
In plain language, veterinary schools in America, plus the American
Veterinary Medical Association, have looked at studies to show how long
vaccines last and they have concluded and announced that annual
vaccination is unnecessary.(16-19)
Further, they have acknowledged that vaccines are not without harm. Dr
Ron Schultz, head of pathobiology
at Wisconsin University and a leading light in this field, has been
saying this politely to his veterinary
colleagues since the 1980s. I’ve been saying it for the past 12 years.
But change is so long in coming and, in the meantime, hundreds of
thousands of animals are dying every year - unnecessarily.
The good news is that thousands of animal lovers (but not enough) have
heard what we’ve been saying. Canine Health Concern members around the
world use real food as Nature’s supreme disease preventative,
eschewing processed pet food, and minimize the vaccine risk. Some of
us, myself included, have chosen not to
vaccinate our pets at all. Our reward is healthy and long-lived dogs.
It has taken but one paragraph to tell you the good and simple news.
The gratitude I feel each day, when I embrace my healthy dogs,
stretches from the centre of the Earth to the Universe and beyond.
