Vegans and Vaccinations
The following article was printed in The Vegan magazine and was compiled by
Gill Langley MA PhD MBiol.
One of our body's most important defence mechanisms is the immune system, which
enables specialised cells and proteins (antibodies) in the bloodstream to combat
'foreign' substances, including bacteria and viruses. When exposed to germs,
the body creates antibodies to deal specifically with them, and in a healthy
person infection is overcome.
Principles ...
The aim of vaccination is to prime this natural defence system. A vaccine consists
of large numbers of killed or weakened bacteria or neutralized toxins. Introduction
of these substances into the body by vaccination results in their recognition
as 'foreign' and the production of antibodies against tyhem. As the vaccines
are not virulent (i.e. cannot cause infection), the main result is that if the
vaccinated person subsequently, the immune system swings into action much more
quickly and gives protection against the disease.
... and Practice
That's the theory anyway; do the results show that vaccination is always successful?
Vaccination, being based on the germ theory of disease, is a central part of
modern medicine. The 'conquest' of the infectious diseases of the last century
and early years of this is often claimed by doctors to be one of the major successes
of modern medicine. But a closer look at the history of medicine reveals a somewhat
different picture.
In his book The Role of Medicine (Blackwells, 1979), Professor Thomas McKeown
writes that the contribution of clinical medicine to the prevention of death
and increase in life expectancy was smaller than that of other influences (and
certainly smaller than is often claimed), and he spends some time dealing with
the part vaccines have had to play. For example, deaths from tuberculosis fell
consistently from the time it was first recorded in 1838, and by the time the
BCG vaccine was introduced in the mid-1950s, deaths had already fallen from
3,500 per million people in 1838 to 200 per million people. The rate of decrease
in deaths from tuberculosis has not changed since vaccination became common,
and McKeown attributes most of the reduction in mortality to increased resistance
due to better nutrition, and to less overcrowding. By comparison with Britain,
the Netherlands has never had a national BCG vaccination programme, but has
the lowest death rate form tuberculosis of any European country.
Since the early years of this century the death rate from diphtheria fell constantly
both during and after the introduction both of antitoxin treatment and later,
in the 1940s, a national immunisation campaign. Even though Professor McKeown
reckons diphtheria immunisation is one of the more successful, he admits that
because deaths from whooping cough and measles also fell over a long period
- when there was not vaccine available - it can't be assumed that vaccination
alone accounted for the decrease in diphtheria deaths. Again, better nutrition,
improved sanitation and housing conditions, and purer drinking water played
a major role.
It's impossible generalise about the successes of vaccines of different sorts.
As we've seen, results depend not only on the effectiveness of each vaccine
but only on the effectiveness of each vaccine but also on nutritional, environmental
and behavioural factors. So it seems that smallpox has been eradicated, at least
for the time being; and yet a study of BCG vaccination in India showed after
seven years that there were as many cases of tuberculosis of the lung in vaccinated
people as there were in those who had not been immunised. Success rates for
BCG vaccine vary from 80% among American Indians to nil among schoolchildren
from Georgia!
Safety
Everyone is concerned that vaccines should be safe, and vegans will also be
concerned about the origins of vaccines and the way they are tested for safety.
In the case of viral vaccines such as smallpox and rabies, in the early days
the virus was obtained from infected animals. Smallpox virus was collected from
skin sores on infected calves. But later developments have allowed the virus
to be grown in cell cultures, and human cells are now used in culture to produce
rabies, smallpox, polio (in the UK), german measles and measles vaccines. Bacterial
vaccines such as diphtheria and tetanus were originally produced from meat broths,
but the bacteria are now grown in chemically-defined liquids.
Each batch of vaccine is subjected to a number of tests before it is sold, and
most of these entail the use of laboratory animals. Safety tests are done to
ensure that there is no active, virulent virus remaining in the vaccine, and
these involve injecting mice, guinea pigs, rabbits or monkeys, sometimes directly
into the spinal cord, to see if any infection results. Potency tests check that
the vaccine really does give protection: two groups of animals are infected
with the disease, and one group then receives vaccination. This group shouldn't
develop the disease, but the other animals aren't so 'lucky'. Finally, the vaccines
have to be tested for purity, to ensure that there are no other infectious viruses
contaminating the vaccine, and these tests are conducted using adult and suckling
mice, guinea pigs and rabbits.
Alternative humane methods of vaccine testing are being developed, such as cell-culture
techniques and biochemical tests, but so far there is no vaccine which does
not at some stage involve animal exploitation.
The safety of vaccines in use remains a contentious issue. If animal tests are
effective, all vaccine batches which 'pass' should be safe for human use, but
this is obviously not the case. Cause of the greatest concern has been the whooping
cough (pertussis) vaccine. In the early 1970s eight out of every ten children
received the triple vaccine, and fears led to a fall in the vaccination rate
so that by 1977 only three out of ten children had been immunised against whooping
cough, and even now only six in every ten are vaccinated, and mini-epidemics
occur every two or three years.
Until 1968 the whooping cough vaccine was only effective 20% of the time, but
doctors claim that since then the vaccine has been improved. There are, though,
some eminent doctors who regard the whooping cough vaccine as ineffective and
dangerous. A study of its safety was set up, and in 1981 reported that the risk
of permanent brain damage after pertussis vaccination was 1 in 110,000 injections.
Critics claim that by only counting those children who were hospitalised, the
numbers were underestimated and the risk could be as high as one child brain-damaged
for every 50,00 injections. Earlier this year the controversy was sparked off
again by the sudden deaths of five-month-old twins two hours after receiving
the triple vaccine. So the situation remains unclarified, and although there
is also a risk of brain damage from the disease itself, the words of reassurance
from the Department of Health have a hollow ring to them.
A question about the long-term safety of vaccines has been posed by a study
of measles in Denmark. A team of doctors found that most of the people who apparently
never had measles in childhood actually did have antibodies to the measles virus
in their blood, showing they had been infected but hadn't developed the characteristic
rash. These people developed more apparently unrelated diseases in later life
including such serious conditions as arthritis, bone problems, skin diseases
and certain tumours - than those who had a full-blown measles infection.
The doctors suggest that if a person is exposed to measles but doesn't develop
a rash, the virus may survive and cause illness later on. This casts a doubt
on the advisability of vaccination, which causes a build-up of antibodies to
the measles virus. A doctor will not know when vaccinating a child whether or
not they have already been exposed to infection, in which case measles may be
in the incubation stage. If so, the rash could be suppressed and the virus may
linger in the body, causing much more serious problems in years to come.
This study provides unexpected support for the philosophy of holistic medical
practitioners who have always believed that suppression of illness damages the
body's long-term ability to fight off disease; to them, childhood infections
such as measles help establish natural immunity in later life, and suppression
of symptoms drives disease deeper into the body. The Unitary Theory, common
to all natural therapies, states that the identity of the disease-causing bacteria
or virus is of less importance than the equilibrium of the body, mind and spirit.
Naturopathy
Naturopathy or nature cure has a long history and has been evolved by its practitioners
in the clinical situation largely by observation of humans in health and disease.
Its methods have been developed by practical experience and owe nothing to animal
experimentation. The principle of nature cure is the stimulation of the body's
natural healing powers, both by building a good foundation for health and by
such treatments as diet, relaxation and meditation, and hydrotherapy.
Sound nutrition plays a vital role in naturopathy, whose practitioners advocate
a wholefood diet, with food being eaten as near to its natural state as possible.
Some, although not all, naturopaths recommend a vegetarian or vegan diet for
some of their patients, but all agree that junk foods contaminated with chemicals
or drugs will hinder the body's natural resistance to disease by causing a build-up
of toxins in the tissues. Nature cure practitioners believe that infection is
likely to occur when the natural balance of the body breaks down, and this usually
owes more to emotional, nutritional or mechanical stresses than to bacteria
or viruses. They point to the fact that many people are exposed to germs and
yet don't succumb to illness, their bodies have a high level of natural resistance.
If a child brought up on a health-promoting diet does catch an infectious disease,
s/he is more likely to recover without complications such as eyesight problems,
which can result from measles infection. In treating childhood infections a
naturopath would be likely to 'prescribe' a short fast or fruit juice-only diet
for a few days, possibly combined with hydrotherapy and herbal or homoeopathic
remedies. While this approach may sound highly unorthodox to some, it's worth
remembering that for many years tuberculosis patients benefited from fresh mountain
air and good food at a time when there was no drug treatment. The charted decline
in many infectious diseases in the late nineteenth century was also due mainly
to improved nutrition, purer drinking water and better sanitation, which boosted
people's ability to fight off illness - the basic precept of naturopathy.
Homoeopathy
Homoeopathy, while playing a part in the naturopath's approach, is also a system
of holistic medicine in its own right. Developed nearly 200 years ago, it works
on the basis of treating like with like; remedies are used in extremely dilute
forms which, if concentrated, would actually cause symptoms similar to the illness
being treated. Homoeopathic remedies are prepared from natural substances -
vegetable, mineral, human or animal - and are potentised by special techniques
of repeated dilution. The more dilute the remedy, the more powerful it is.
No-one has yet satisfactorily explained how homoeopathy works, but there is
no doubt that in many cases it has proved to be extremely effective. Because
different remedies may be used to treat the same illness in different patients,
homoeopathy isn't amendable to orthodox scientific methods of assessment, such
as large-scale clinical trials and animal experiments. Nevertheless, some scientists
have misguidedly conducted animal testes on an effort to establish the efficacy
of homoeopathic treatment. Homoeopathy was originally developed through provings
on people and, despite occasional animal tests, such is still the case when
new remedies are discovered. Vegans must be on the look-out for remedies derived
from animal substances such as bee venom and cuttle-fish ink, and should also
bear in mind that many remedies are made in tablet form containing the milk
sugar, lactose.
Homoeopathic remedies can be used preventatively or curatively and there are
remedies for most childhood infections, such as Germany measles and whooping
cough.
When cholera struck London in 1854, the London Homoepathic Hospital treated
many patients. On the release of official statistics on the epidemic, it was
found that 54,000 people had died of cholera. Of these, 59% had died while receiving
orthodox treatment, while of the patients treated homoeopathically only 16%
died. This prompted the then Medical Inspector to remark "If it should
please the Lord to visit me with cholera I would wish to fall into the hands
of a homoeopathic physician!"
For vegans, whether concerned chiefly about animal exploitation or natural health,
there is ultimately no easy answer to the vaccination question. I hope, however,
that this article has provided some guidance in the matter.
