Are Vaccines Still Necessary?
>> Sunday, August 19, 2012
Vaccines, whether they are for people or animals, have become a very controversial subject. They serve to protect us and our pets from life threatening illness. However, like any medication, they can also cause side effects in certain individuals. Basically, vaccines expose the patient to a small infection. This ‘infection’ then triggers the immune system to respond by developing antibodies or immunity to the infectious organism. Then, when the patient is exposed to a full blown infection, their body can effectively fend off the disease. Vaccines are created in such a way that they trigger that immune response, but spare the patient the illness necessary with a natural infection.
One of the main reasons we do not see diseases like polio, canine distemper, and rabies in our communities is because of vaccinations. Vaccines reduce our risk of illness when we travel and prevent us from spreading those diseases. Even though certain diseases are uncommon or absent in our community, vaccination may remain necessary.
The vaccines that are selected for a patient are variable, depending where they live and what our pets do and where they travel. Veterinarians have become better at selecting vaccine protocols to fit our patients. We have also become more prudent recognizing that yearly vaccine protocols are rarely warranted and that vaccine titers can be used to assess whether vaccination is even necessary. We have also become careful about how vaccines are administered. All these efforts help in limiting potential side effects.
Vaccine reactions are rare, however vaccination does carry inherent risks. Just as in people, minor allergic reactions, local inflammation, pain, local tumor growth, or even life threatening shock and anaphylaxis may all occur as a result of vaccination. These events are very uncommon and are far outweighed by the risks of disease. We have learned that vaccines should not be administered to patients that have previously suffered from immune mediated diseases or cancer since vaccines could cause these patients harm.
Vaccines are important because infectious diseases still exist. The viruses and other infectious organisms we vaccinate against are a constant threat and they are changing and developing all the time. Vaccines and vaccine protocols are changing too. Also new diseases are emerging that warrant completely new vaccines. Major veterinary groups such as AAHA, AVMA and ACVIM have responded to the changing canvas of infectious diseases in our country and our expanding knowledge about our pets immune systems, by creating carefully crafted vaccination protocols.
We at Veterinary Care Specialists and VCS Pets First have considered all the available scientific data and created a series of vaccine recommendations for the life of your dog or cat. These protocols can be found at www.vcsmilford.com or www.vcspetsfirst.com.
