Pet Health: Vaccines...What's the Controversy?

I am old enough now that I can still recall the days of taking my dachshund, Rusty to our veterinarian in Westerville OH and getting his "rabies, distemper, and lepto" vaccines (those were the days BEFORE parvo...if you can believe that). I remember Rusty having a reaction (hives) and we opted to not vaccinate for lepto anymore, but it was only after a long discussion with our veterinarian.

As you may have seen in another recent post I had, the Alabama House just okayed the use of 3 year rabies vaccines in that state

Fast forward to this morning as I spent a good 20 minutes on a pet forum carefully crafting an answer to someone who thinks that veterinarians are scamming clients by charging too much for vaccinations and that everyone should just buy the vaccines from the local farm and feed store. I followed that by reviewing news video from Georgia about vaccines can be problems for pets...(here's the linkbut you will have to search for "pet vaccines" to see the video)

WHY all the controversy? Why do "pet experts" on the Internet or in the media think that they know more than veterinarians??

We know that vaccines help prevent disease...that much is fact as we have seen from the literal extinction of smallpox, the reduction of polio, and our low rate of rabies among our dogs and cats. We also know that some vaccines create a longer lasting immunity than other vaccines. But, if you listen to the media (and I referenced this in the last posting) you would think that millions of pets are dying from vaccines and that these newer guidelines mean that you don't have to go to the veterinarian at all!! I am continually amazed at the sheer amount of BAD information on this subject that is prevalent in the mass media and the new media of the Web.

Let's do a little history here: When vaccines for pets first became prevalent (around the 1950s-1960s) little research was done as to the duration of immunity created by the vaccines. The manufacturers of vaccines said "re-vaccinate annually" and veterinarians did so. Also, vaccine technology has changed...we have moved from using "killed" viruses to modified live viruses and even recombinant DNA technology to create vaccines. As we have gotten "smarter" about vaccines, veterinary science started making changes to recommended protocols.

Around the mid 1990s, this topic really gathered steam as scientists and veterinarians started searching for a correlation between an aggressive cancer in cats (fibrosarcoma) and vaccines. Some people also believed that there was a connection between recent vaccine events and immune mediated problems in dogs. Science has shown that some cats do develop these terrible cancers when they are injected (vaccines, antibiotics, etc), but not all cats will develop them. I saw one study from showing that about 1 in 30,000 cats develop this cancer.

Both the American Veterinary Medical Association (AVMA) and the American Animal Hospital Association (AAHA) recommended going to an extended vaccine protocol as the science and information got better. This happened as early as 2001 and some veterinarians had already changed protocols at that time. The majority of veterinarians now recommend vaccinating for "core" vaccines, like canine distemper, feline distemper, canine parvovirus, and rabies every 3 years instead of annually. Other vaccines, like feline leukemia, Bordetalla, Lyme Disease, and others, should be used based on the risk factors that your individual pet has. The best way of determining those factors is to have an open discussion with your veterinarian.

So far, this seems pretty straightforward...but the confusion and the controversy comes about when people equate veterinary visits with vaccines. I can't stress this enough....the most important reason to see your veterinarian is to have a good physical examination done on your pet. I recommend twice yearly examinations, but all pets should go at least once yearly. Also, trying to save money by vaccinating your pets yourself is also a potential for disaster. First, how do you know that the vaccines have been handled properly at your local farm/feed store or pet store? Next, do you know all the components of the vaccine you are about to give? What if your pet isn't at risk? Why should you give that vaccine?

Veterinarians and their staff members want your pet to be "immunized" not just poked with a needle. If you have questions or concerns about your pet's vaccine schedule, talk with your veterinarian. Find out your pet's risk factors and the potential effects of not vaccinating. Titer tests are available to check antibody levels for certain diseases, but be forewarned that they are not 100% understood (is your pet truly protected) and they can be quite a bit more expensive than the vaccines themselves.

You can also post questions to veterinarians at www.PetDocsOnCall.com. Our doctors will be sure to provide you with accurate information that you can trust...after all, its from a veterinarian!

This topic is still quite controversial and has many tangents and side avenues to explore. I welcome your comments and questions and hopefully we can both learn a little bit more about keeping our furry friends safe!

I am certainly glad the vet community is examining and discussing the practice of vaccinating on a more individual basis. However I am concerned, like others, that this means a vet might only see his or her canine patient for a check up once every three years, this also means that certain health issues can go untreated for much longer periods of time. We really need even more widespread education on pet care: even though your dog doesn't need a rabies vaccination every year, good animal health requires a yearly visit. There are a list of reasons a pet should see his or her vet at least once a year (perferably twice a year) the most important that comes to mind is heartworm testing and a dental check up or cleaning. An easy reminder is to make a yearly appointment on your dog's birthday!
