Reaction to
lepto in vaccine
Question: Dr Richards,
I am the proud owner of two miniature schnauzers which are closely
related. I brought one of them,Derby, who is 1 year old, for her second
Rabies and Distemper shot, and she had a severe reaction to the lepto
portion we believe. The first shot she had last year did not include
lepto. Well, the shot that was administered this year did and the dog
was
very pale,lethargic and vomitted. She appears to be fine now thanks
to her
being at the vet after the shot was given. My question is given the
one
dog's reaction do you recommend not vaccinating against lepto again
for
this dog or my other dog. We live in North Carolina. Is it worth the
risk?
Answer: Patty-
We do not use combination vaccinations containing leptospirosis at all
in
our practice. The leptospirosis portion of the vaccines seems to cause
the
most reactions and leptospirosis is not common in our area. This
situation
does vary from one area to another and it is possible that there is
more of
a problem with leptospirosis where you are. If your vet feels the risk
of
the disease is low then skipping this portion of the vaccination seems
like
a good course of action, to me. The recent outbreaks of leptospirosis
in
Long Island and other areas have been to types (serovars) of leptospirosis
that are not included in the standard vaccinations. If there is a problem
with lepto in your area it might be better to consider using the new
vaccination for leptospirosis (I think it is from Ft. Dodge) that has
several types of leptospirosis in it.

Vaccination problems
Question: As a subscriber to your service, I'd like your opinion
on yearly vaccines
for an 11 year old Yorkshire Terrier. I'm hearing mixed reviews on
this
subject. Some are saying the build up of vaccines are harmful. She
is 5.5lbs
and suffering from heart problems. Currently she takes Vasotec, Atenolol,
Furosemide and Digoxin.
Thanks, Pegge
Answer: Pegge-
I have not seen any really good evidence to suggest that there is a
syndrome of caused by "over vaccination" or that there is a buildup
of
problems due to repeated yearly vaccination in dogs. There are some
veterinarians making these claims but they have not produced any really
solid evidence that I am aware of at this time.
On the other hand, there is evidence that vaccinations do sometimes
cause
complications, such as a brief period of immune suppression, allergic
reactions and evidence that vaccines can on rare occasions induce
immune-mediated hemolytic anemia (IMHA) in dogs. In cats, vaccinations
have been shown to increase the rate of fibrosarcomas, which are a
particular type of cancer. No such problem is known to exist in dogs
at
this time, though.
Vaccines have saved the lives of a great number of dogs and cats. However,
if there are problems, even if they are rare, with vaccine administration
and the vaccines provide more than a year of protection, there is a
feeling
among many veterinarians that the interval between vaccines should
be
increased. Whether or not that will affect your Yorkie depends on where
you
live, the lifestyle of your dog and the risks of various diseases based
on
that assessment.
At the present time it is fairly safe to say that parvovirus and distemper
vaccinations last much longer than one year, once there is a good response
to the vaccine. It is usually safe to assume that there has been a
good
response if a dog has had the puppy vaccination series and been
revaccinated at least once or twice. I do not know how long adenovirus
and
parainfluenza virus protection lasts from the vaccines. Leptospirosis
vaccines probably provide less than a year of protection. I do not
know the
duration of immunity from Lyme disease vaccination. Rabies vaccine
lasts
between three and five years but some states require yearly vaccinations
for this virus and almost all states require revaccination after three
years.
So even though I don't think there is a problem that can be related
to
vaccinating at yearly intervals, I don't think all dogs require
vaccinations at yearly intervals. Dogs that live in areas where
leptospirosis might be a problem may require vaccination twice a year.
Other dogs may only require vaccination every three years or so.
I do think it is really important for dogs to have a yearly physical
exam
and I think that most would benefit from at least once a year teeth
cleaning and dental exams, too. So I wouldn't put off a visit
to the vet
but if you are worried about vaccinations you might want to ask how
likely
it is that your dog will be exposed to the various diseases it has
been
vaccinated for and what the best vaccination interval for your particular
dog might be.
If your vet is reluctant to discuss this issue and prefers to stick
to a
yearly vaccination schedule for all dogs, he or she is not in the minority
at the present time. I tend to worry a little about vaccinating
pets when
they have problems like heart disease that requires several medications
to
control, though. Even a slight reaction from the vaccine can lead to
more
complications in these patients. I would really take a hard look
at how
much risk there really is for the various diseases you might consider
vaccinations for in this case and try to eliminate any unnecessary
vaccinations.

Limping after
vaccinations
Q: Dr Mike, I have a 1 year old male, neutered,
Akita/Golden Retreiver mix, who had his shots just today. After his return
from the Vet, I noticed that he was limping on his right leg, and all throughout
the day. Is this something to be concerned about? I know that when they
get their shots, they will be sore, but does this relate to his limping?
Should I give him asprin, or should I not really worry too much as this
will subside soon? Thanks, Bobbie
A: Bobbie- I am hoping your dog is fine now but
I thought it would be best to answer your question. It is always better
to check with your vet whenever anything unusual happens after vaccinations
or after a new medication is started. There is a good chance that the problem
is not directly related to the vaccination but more to the car ride, getting
on and off the vet's table or something like that. But it is always best
to check with your vet if you have a question about a change in behavior
or physical signs of illness or injury that occur after an office visit.

Vaccination
lumps - seromas and abscesses
Q: Hi my name is Jorge and I want to tell you that
my dog have a problem because the doctor put the vaccine in a wrong way
or place and it have a really big ball where the vaccine was put near the
stomach. The doctor said that he will have to remove it if it dont get
more liquid and if get liquid he will take it out with a syringe. I wonder
if you can tell me if another thing may be done. If you dont understand
write me . Thank you Jorge.
A: Jorge- I am pretty sure that your dog is probably
better by now. Sometimes lumps do form where vaccines are given. If these
are fluid filled lumps they are usually either abscesses or seromas. An
abscess is an infected pocket under the skin and they are a rare problem.
Seromas are accumulations of serum, the liquid portion of the blood, under
the skin. These occur when the vaccine irritates the veins in the area
and they leak serum or if there is bleeding under the skin, perhaps due
to the needle passing through a vein or skin artery. These are more common
than infections (abscesses) and they tend to go away on their own after
one to three weeks. It is always a good idea to let your vet look at any
lumps that form after vaccination, which you seem to have done. I am sure
your vet will keep working with you to resolve this problem as long as
is necessary.

Allergic to Vaccination
Q: I have a 7 yr. old Shih Tzu that has had allergic
reactions to any type of vaccination. Her last vaccination (rabies) she
had severe hives, swelling of the face (eyes swollen shut) and throat.
The vet had to give her a shot in her front leg and keep her for observation
the rest of the day. The vet said she is apparently allergic to the egg
culture the vaccine is grown in. What do I do when she is due for her rabies
shot next time?
A: There are new vaccines coming on the market,
hopefully this year, which utilize recombinant gene technology. These vaccines
should be much less likely to produce allergic reactions as they usually
do not require adjuvents (the extra ingredients in vaccines which help
make the immune system react to the vaccine). It may be a good idea to
ask your vet about the use of one of these vaccines if they have been marketed
when your dog needs to be vaccinated next time. I don't think any of the
currently available rabies vaccines are grown in egg culture anymore but
I could be wrong. It is possible that your dog is reacting to the rabies
virus antigen or to the vaccine adjuvents.
It is usually possible to control acute allergic reactions to vaccination
by preadministration of antihistamines and/or corticosteroids. For "booster"
vaccinations it does not appear to interfere with immunity to administer
corticosteroids concurrently with the vaccination.
If it wasn't rabies vaccine that your dog was reacting to, I'd probably
just advise skipping the vaccination. This isn't possible for rabies vaccines
since they are usually required by law and there is some risk to your pet
in the event he bites someone and is not vaccinated. Long quarantines or
even euthanasia to allow examination of the brain for rabies virus may
be necessary when a dog with an expired rabies vaccination bites someone,
even accidentally. Ask your vet about the newer vaccines. There is a good
chance they will be available within the next year.
