At some time in its life, your pet may be exposed to a serious or even fatal infectious disease like parvovirus. Having your pet vaccinated is the best and least costly way of preventing disease. Without proper vaccination, he is left unprotected.
When your dog or cat is vaccinated, its immune system produces special substances called antibodies. The antibodies work against viruses or bacteria that cause disease and can be regarded as the body’s “fighter pilots”. It is important to note that vaccines are preventative rather than curative. Vaccinating a sick animal is not going to help and in fact is not advised. A healthy pet with a healthy immune system is required in order to build these protective antibodies in response to a vaccine.
