Vaccine Release Form


Vaccination Procedure:

Your dog, cat, ferret, or guinea pig will be given a vaccination that is a solution of killed or weakened viruses, bacteria, fungi, or protozoa that is administered under the skin, in the muscle, or in the nose. The vaccination is designed to stimulate your pet's immune system before exposure occurs to protect him/her against disease.

Vaccination Reactions and Risks:

As with any medical procedure, vaccinations are not risk free. Three categories of complications can occur: Vaccination Failure, Mild Reactions, and Serious Reactions.

With Vaccination Failure, a small portion of any population of pets may not respond adequately leaving the pet unprotected. It's hard to predict which pets won't respond and it is not practical to do titers on every pet.

Mild Vaccination Reactions occur in about one in four vaccinated pets. Mild reactions are rarely life threatening but should always be reported to the veterinarian and may necessitate a doctor examination. Mild vaccination reaction symptoms include:

1). Facial and lip swelling.
2). Hives and itching.
3). Pain and swelling on the skin, in the muscles and the joints.
4). Sterile abcesses.
5). Transient lethargy with fever.
6). Vomitting and diarrhea.
7). Hair loss at the injection site that may be temporary or permanent.
8). Sneezing.
9). Mild signs of the "disease" vaccinated for.

Mild vaccination reactions usually respond rapidly to treatment.

Serious Vaccination Reactions are very uncommon; occurring in less than one in ten thousand pets (.01%). Serious side effects always necessitate a doctor exam or an emergency exam if occurrence is "after hours." Serious side effects include:

1). Anaphylaxis and shock.
2). Immune mediated diseases causing inflamed blood vessels (vasculitis), low blood cell and platelet counts.
3). Tumor formation at the vaccination site called a "fibrosarcoma."

Fibrosarcomas can be aggressive and fatal. These tumors seem to be most commonly associated with rabies vaccines but any vaccination can cause them. These growths usually occur in cats only.  Any serious side effects can be difficult to treat successfully.
