The
cat
vaccination recommendations
given to me by my vet (as at 2007) were to come back every year. This
was endorsed by boarding catteries in the UK who insist on a
certificate. The routine
booster vaccinations in the UK are Feligen RCP and Leucogen (or
equivalent). An
equivalent booster vaccination is the (1) Nobivac Tricat and (2)
Nobivac FELV. That is or was the "routine" but in truth it is less
certain than that.
The whole subject of vaccinations is fraught with difficulty and lack
of clarity. The public, people who keep cats, are in the hands of their
veterinarian and their views vary widely, it seems to me. Information
on cat vaccination recommendations is scrambled because of a number of
factors:
Financial Profit
Pressure
to make financial profit is probably the biggest driving factor in how
frequently to administer cat vaccinations. This is profit for the big
drug companies and the veterinarians themselves. To bring in a cat
every year is a wonderful way to build bread a butter business. The
"shot" can be administered and a check up given at the same time. The
check up will no doubt result in some further treatment. Bingo. Nice
profit. Sounds cynical? It is the truth in my opinion.
Research
Another factor which seems to blur the picture is that research appears
to be ongoing and is not clear itself. One thing is certain, though, is
that there has been over vaccinating for the reason above, I suspect.
Also who does the research. Probably big drug companies who are driven
by one thing: $.
Risk
Cat vaccinatioon recommendations must be based on risk assessment.
There are two risks. The risk of catching the disease for which a
vaccination is given and the risk of being injured by the vaccination.
These risks need to be researched and they are dependent on the cat's
health, age, and behaviour (indoor cat or outdoor cat). When this
complex picture is made more complex by possibly biased research in
favour of vaccinating you can see how confusing it is for laypeople
like me and other cat owners.
The first interesting thing about cat vaccinations is that humans don't
have booster vaccinations every year. Why are we different? We aren't
that different except we are people and we can make requests and cats
can't. Vaccinations last a long time and don't need
boosting for humans. That single factoe must inform us as to how we
treat our cats.
Most people receive very few regular vaccinations once they reach
adulthood. We only get special vaccinations as and when required (e.g.
travelling abroad).
It is now thought that yearly cat vaccinations may be unnecessary and
could on occasions cause health problems for your cat. The views of
vets differ probably because some are more financially ambitious than
others.
Without widespread disease (epidemics), it is sensible to ask whether
it is wise to vaccinate
regularly, particularly as vaccination carries its own potential health
risk?
Let us remind ourselves that a vaccination is a proactive measure based
on the riskof
getting a
disease. A vaccine works by stimulating the cat's natural immune system
to produce antibodies.
These are immunoglobulins, which identify and neutralize foreign
objects such as bacteria and viruses.
The need for vaccinations is a decision based on balancing
risks (like an insurance policy).
As mentioned, my reading of the situation is that this is a developing
area (i.e.
work in progress) and that there is currently not enough information
for definite overriding recommendations to be given by the authorities.
But, it
seems that cat vaccination recommendations should be based on the
premise that a vaccination is a procedure (one off) as opposed to a
necessary and automatic event.
That means that vets and cat keepers need to make individual decisions.
These
will vary depending on the vet and the personal circumstances of the
cat concerned (some cats are more at risk
than others).
Individual vets will give individual cat vaccination recommendations.
Decisions
Based on the above introduction, the decision whether to forgo a
vaccination will be made
by your vet, but talk to him or her about the need for a
vaccination. The key is no doubt to find a vet who is genuinely
interested in providing care for your cat of the highest standard and
who makes decisions in that regard that are devoid of monetary concerns.
We are reliant on vets because if we research the issues ourselves we
do not find clarity. A good veterinarian will have the knowledge to
find clarity of decision making.
The first of the vaccinations mentioned above is a multi-vaccination
against (a) Feline Panleucopenia, (b) Feline Viral Rhinotracheitis and
(c) Feline
Calicivirus. The second (FELV)
is Feline Leukemia. Vaccines don't make
the cat immune to the disease. They reduce the severity.
(a) Feline
Panleukopenia: This is Feline
Distemper. It is caused by
the feline parvovirus (FPV). It is nasty, spreads fast and can kill
(especially young cats). This can be given, it seems, every 3 years for adult
cats.
(b) Feline
Viral
Rhinotracheitis:
This is the Feline Herpes Virus
(FHV). This causes cat flu and is very infectious. It can kill
(particularly kittens) and can cause permanent damage to kittens.
(c)
Feline
Calicivirus: This is also a
cause of cat
flu. The vaccine
can apparently be given
every 3 years.
(d) Rabies
(but
this may be in only certain countries)
FeLV is a serious disease. The vaccine, it could be argued, is also a
serious procedure (my
thought) as it has the potential to cause Vaccine Related Sarcoma
(cancer) it seems (see cat
health and cancer). Research has
been carried out and the incidence
of
this occurring
is low being 1 in 1,000 to 3 in 10,000 cats. The rabies vaccine may
also result in cancer (according to some studies)
See
this page if your cat is
sneezing. See
this page if you want to read
about FELV
and adopting cats
suffering
from this disease.
Having read and researched this matter some more please forgive me for
updating this page. Veterinarians thought that vaccinations were safe
procedures without risk. It almost seemed at one time as if they should
be done automatically.
However, vaccinations can cause short, medium and long term health
problems:
short term -
anaphylactic shock - I'd make sure
your cat was alright after the vaccination and wait for a while in or
near the surgery in case. This may sound severe but it is all about
risk taking in the end.
medium -
injection site reactions.
long term -
development of cancers at the site
of the injection caused by some of the ingredients of the vaccine.
there is a
suggestion that over vaccinating can cause
or contribute to a condition called Feline
Hyperesthesia.
immune system
damage.
Feline
Fibrosarcoma a form of cancer
can
(rarely I presume - actually 1 in 1,000 to 1 in 10,000 according to the
Wikipedia author) start growing at the site of the vaccination.
Studies revealed that multiple repeat vaccinations (I also presume
yearly) at the same part of the body could result in this cancer
developing.
It is not clear as far as I can see as to what aspect of the
vaccination exactly causes the cancer. It might be the immune-booster
substances in certain vaccines. As a result new recommendations were
instigated (see below). It seems that additives to the vaccine called adjuvants
are responsible. These are
substances that modify the effect
of the vaccine and in the case of feline vaccines is composed of
aluminium, which caused inflammation at he site of the vaccination.
The standard vaccines are listed above. There are
others. Consideration should be given by the vet before administering
the others. I would have thought that even the standard vaccinations
should no necessarily be given yearly if for example the cat
is old, indoors all the time and there is no contact with other cats.
Further
Update: The
American Association of Feline Practitioners have made cat vaccination
recommendations:
Vaccine for
feline leukemia virus (a non-core
vaccine) (FeLV) be given only to high risk cats and kittens
the core
vaccines referred to above (a-c) be given
every three years to adult cats (what happens to kittens?)
Vaccines should
be administered in areas that would
make surgical removal of Feline
Fibrosarcoma easier should it
occur.
A rabies
vaccination not containing an aluminium
adjuvant does not apparently cause inflammation. I don't know if this
vaccine was created at the instigation of The American
Association
of Feline Practitioners.
Note:
these are my
views. The
views of people other than vets can be useful. Vets are fantastic but
they are in business. If you want to just see a chart with American
Association of Feline Practitioner’s Guide
to Vaccinations when
considering a protocol for your cats, then

Recommendations.
Further
update Feb 2009:
Here is a sample
of some views from cat breeders.
Their views differ as do the views of vets. This can cause uncertainty
and worry for those trying to do their best for their cats and in
deciding the best cat vaccination recommendations:
Do
not have your vet give the
three way and the rabies during the same visit!
Ft. Dodge all-killed has aluminum adjuvant in it and that is what
causes point of injection cancers and
lumps forming as well as suspected immune reactions. Ft.
Dodge is the only mfr. to have come up with a calici vaccine that
protects against virulent fatal systemic calici,and that is MLV.
Using Fort Dodge 3-way killed
for over 15 years and have never had a
kitten have a reaction
Unfortunately, consulting with vets is not always
the wisest
decision.
Intra-nasal vaccines -- sometimes these
vaccines cause problems in kittens.
I have never
heard of any
problems with Ultranasal vaccines in kittens
when used properly.
It does list the
FeLV as
being NON CORE - that means it is optional - the
only thing they list as Core are FVRCP & Rabies where required
by
law.
Further update
July 2009:
Dr. Rogers of the Critter Fixer Pet Hospital,
Inc.™(link opens in a new
window)
is
clearly a man of integrity and does the right thing for animals. I have
not met him and don't know him. I can only judge by what he says and he
says the following on rabies vaccinations. This is not verbatim as that
would be a copyright violation.
Scientific research has shown that vaccinations for Rabies, distemper
and parvovirus work for at least 7 years.
Yearly booster
shots have no benefit. (My comment: The opposite is the case because of
the risk associated with delivering a vaccination). However, the law in
Texas requires that the rabies vaccination be carried out yearly. This
is too much Dr. Rogers says and he has tried to change the law.
Non-adjuvant type vaccines that are licensed for a year can be used to
minimise the risk of getting cancer from a vacccination.
Cat
vaccination recommendations -
Conclusion
If there are conclusions it is these:
Don't assume
that the routine
vaccinations should be carried out every year. Discuss the matter with
a good vet to get the best cat vaccination recommendations for your cat.
Don't assume cat
vaccinations are always safe, they are not. Adjuvanted
vaccines have been incriminated as a cause of Injection Site
Fibrosarcoma in cats. This form of cancer will kill your
cat. There is still a question mark over the whole concept of
vaccinating. Vaccinations can damage your cat's immune system.
Cats who are
exposed more (e.g. cats who stay out a lot or meet
other cats a lot) to the transmission of disease
are more at risk and that plays a part in decision making.
Vaccinations are
a balancing act between the risk of
getting the disease which the vaccination is designed to protect
against and the risk of getting ill because of the
vaccination. Only one person can decide that - the vet. Therefore he or
she must be reliable.
The vet advises,
you decide. Stand up to a vet and don't take the usual platitudes
without questioning if you are concerned about your cat.
Vaccinations are
one part of the many elements needed to create a
healthy environment and life for cats. Cat Vaccination recommendations
need to take that into account.
I was going to resist trying to actually state some cat vaccination
recommendations but I think I can. It will always be a compromise and
the following cat vaccination recommendations come from the "Irreverent
Vet" on the PetPlace.com website. I think this is the website owner's
thoughts (a vet) and my judgment is that they are reasonable. In the
end, regrettably, we have to make a judgment as we cannot wholly rely
on our veterinarian, which frankly is a shocking state of affairs:
Indoor Cats - no
risk of exposure to outside cats
Full set of kitten vaccinations & booster when one year of age.
Rabies vaccinations are governed by law in the USA. The minimum is
administered. Thereafter vaccinations are three yearly until aged 10,
when they stop.
Indoor and Outdoor
cats
Full set of kitten vaccinations & booster when one year of age.
Rabies vaccinations are governed by law in the USA. The minimum is
administered. These cats are also vaccinated for feline leukemia virus
and feline immunodeficiency virus on a yearly basis. They are also
vaccinated for the feline distemper combination vaccine on a three
yearly basis. At aged 10 vaccinations stop.
As for me and my cat, I stopped vaccinations ages ago because I decided
that she didn't need them on a balance of risk as she is an old
semi-indoor cat who was well vaccinated (over vaccinated) in the early
years of her life. Also I have to say that I think even the moderated
recommendations by the "Irreverent
Vet" are too high. There are real question marks against vaccinations.
I wonder what would happen if we stopped althogether?
It
is also worth remembering that even experienced cat breeders who
routinely provide medical care for their cats are soemtimes unsure or
have conflicting opinions on cat vaccination recommendations.
