Should Your Dog Get the Lyme Disease Vaccine?

By Ruthie Bently

I have lived in southern Minnesota for almost twelve years now. We don’t usually see ticks of any kind before May, when the temperature warms enough up for them to become active; this year was the exception to the rule. After a ramble with Skye I found the first tick, not on Skye but on my own arm. It was only the second week of March.

There are eight ticks in the United States that are responsible for ten diseases people catch; Lyme disease is one that our dogs can catch too. The Deer Tick or Black-Legged Tick (Ixodes scapularis) is not the only tick that carries the bacteria that causes Lyme disease. It is also carried by a tick known as the Western Black-Legged Tick (I. pacificus) on the West Coast of the United States. It was originally thought that only the Northern Deer Tick (Ixodes dammini) was a carrier of Lyme disease. The Lone Star Tick (Ambylomma americanum), Ixodes Angustus, and Ixodes spinipalpis have been shown in experiments to be vectors of Lyme disease. This means that due to the development of the disease, there could be more than three ticks we have to worry about in the future. Depending on your location in the United States, from 1% to more than 90% of the ticks can be infected with the bacterium Borrelia burgdorferi that causes Lyme disease. The nymph stage of the tick life cycle is the most common for Lyme disease transmission.

Chemical and medical preparations for tick prevention have been around for many years: collars, powders, chewables and topical treatments to protect for a month at a time. There is currently a vaccine available for canine Lyme disease, but there are pros and cons for it. As a responsible pet owner, I always look at something from all sides before I make a decision, because I want the best for the creatures in my care. While the vaccine is reputed to keep your dog from getting Lyme disease, there are dogs that have been vaccinated that have still contracted Lyme disease. Proponents of the vaccine state that it will keep a dog from becoming a carrier and transmitting it to their owner. When I asked my vet about this, he stated you can’t get Lyme disease from your dog; it comes from a tick and cannot be passed from dog to human.

One manufacturer guarantees their vaccine and states that they will pay for 50% of any treatment a dog needs if they do contract Lyme disease. While this sounds good, I have to wonder why they’re only offering to pay for 50% of the treatment. This makes me question vaccinating my dog against the disease in the first place. Other things to consider are that the Lyme vaccine only provides immunity for a short time span, and needs to be administered yearly. It can cause an untreatable, fatal form of Lyme disease. None of the veterinary schools in the United States recommend it. Prolonged use of the vaccine can cause kidney problems in dogs.

Many dogs do not show symptoms of Lyme disease until they have had it for between four and six months, and some dogs never show symptoms. The Canine SNAP 3DX (or C6 SNAP) is a test for antibodies in a dog’s body specific to Lyme disease and should not be affected if you dog has been vaccinated for Lyme disease as the antibodies are only present after infection. Your vet can perform the test and it’s reputed to be very accurate in Lyme detection. If your dog tests positive, the Lyme Quantitative C6 Antibody test is suggested as a follow-up. It can be used as a baseline not only for diagnosis, but for indicating progress in the therapy of the disease.

If contracted by dogs, Lyme disease can be treated either allopathically or holistically. However, because of the seriousness of this disease to your pet’s health, this is not one you can attempt to treat by yourself at home, with an over the counter fix. You need to seek veterinary help.

In my opinion, vaccinating for Lyme disease is a bad idea, and I live in one of the states where Lyme disease is high for dogs. It may lull you into a false sense of security; there are other tick borne diseases that our dogs can contract. The other diseases aren’t going away any time soon and if history is any indicator they may just get worse. Tick prevention should be a consideration in your line of defense. After all, Lyme disease started in Lyme, Connecticut and now is nationwide. Whatever you decide to do, make sure you seek the counsel of your veterinarian before you decide whether to vaccinate for Lyme disease, or not.

Lyme Disease Vaccine for Dogs

 LYME–Vaccinate or Not?

PERMISSION GRANTED TO CROSS-POST THIS MESSAGE.
In response to questions about Lyme disease in dogs and the Lyme vaccine, I would like to share the advice that Dr. Ronald Schultz, Chair of Pathobiological Sciences at the University of Wisconsin School of Veterinary Medicine gave me for my 2 dogs, who both receive(d) (one died in July from a mast cell tumor which developed at a rabies vaccination site) 100+ tick bites a summer.
I was concerned after having contracted Lyme twice myself; however, none of the dogs we have had over 30 years were ever vaccinated against Lyme or ever contracted the disease. After getting it myself, I was reconsidering. Dr. Schultz advised me that there was far more risk associated with the Lyme vaccine than there was with antibiotics to treat the disease if one or both dogs contracted Lyme.
He further explained that if they tested positive for Lyme, but displayed no symptoms, then not to treat them with antibiotics because it indicated that they had been exposed to the disease, but hadn’t contracted the disease. However, he said, that if they tested positive for Lyme and had symptoms (lameness, fever, lethargy, etc..), then start treatment. Dr. Schultz elaborated by telling me that in vaccinology, immunology, the point is not to prevent infection, it is to prevent disease. In fact, low-grade infections are introduced to elicit immune responses, which is how vaccination works, by introducing an attenuated (weakened) antigen into the animal’s system.
Further, he said that a positive Lyme test in an ASYMPTOMATIC dog merely reflects the fact that the dog has been exposed; positive Lyme test in a dog with SYMPTOMS indicates that the animal has contracted the disease and needs treatment.
Based on his advice, I have chosen to not vaccinate my dog(s) against Lyme. Below are links to a few articles on the subject which may help you in deciding whether or not to vaccinate your dog against Lyme.
Lyme is a “killed” vaccine and is associated with clinically significant adverse reactions. According to the 2003 AAHA Guidelines (Page 16), “…killed vaccines are much more likely to cause hypersensitivity reactions (e.g., immune-mediated disease).” Further, the AAHA task force reports on Page 18 that, “Bacterial vaccines, especially killed whole organism products …..are much more likely to cause adverse reactions than subunit or live bacterial vaccines or MLV vaccines, especially if given topically. Several killed bacterial products are used as immunomodulators/adjuvants. Thus, their presence in a combination vaccine product may enhance or suppress the immune response or may cause an undesired response (e.g., IgE hypersensitivity or a class of antibody that is not protective).”
Dr. Alice Wolf, Professor of Small Animal Internal Medicine at Texas A&M College of Veterinary Medicine, stated in an address Vaccines of the Present and Future WSAVA 2001 – Vaccines of the Present and Future at the 2001 World Small Animal Veterinary Association World Congress that Lyme vaccines : “are only partially effective and may cause serious immune-mediated consequences in some dogs that are as serious or more serious than the disease itself…..The most reactive vaccines for dogs include leptospirosis bacterin and Borrelia [Lyme]vaccine .”.

No Lyme Vaccine for Charlie Nancy Freedman Smith, Maine Today Error
“It is not a scientifically based recommendation to suggest that all dogs in Maine should be vaccinated with Lyme Vaccine. There may be select areas in the state, “hot spots” where infection is very high and vaccination would be indicated, but dogs in most parts of the state would probably not receive benefit and may actually be at risk of adverse reactions if a large scale vaccination program was initiated. Wisconsin has a much higher risk of Lyme than Maine, however at our Veterinary Medical Teaching Hospital (VMTH) we have used almost no Lyme vaccine since it was first USDA approved in the early 1990′s. What we have found is infection (not disease), in much of Wisconsin, is low (<10% infection). As you know, infection does not mean disease. About 3 to 4% of infected dogs develop disease. In contrast, in Western and Northwestern parts of Wisconsin infection occurs in 60 to 90% of all dogs. In those areas, vaccination is of benefit in reducing clinical disease. …….. Also, vaccinated dogs can develop disease as efficacy of the product is about 60 to 70% in preventing disease, thus antibiotics must be used in vaccinated dogs developing disease, just like it must be used in non-vaccinated diseased dogs. Therefore, in general areas with a low infection rate <10>50%) then the vaccine will be very useful. Thus, I believe it is irresponsible to suggest that all dogs in Maine should be vaccinated . Veterinarians should know, based on diagnoses in their clinic and other clinics in the area (town), how common the disease would be and they should base their judgment to vaccinate on risk, not on a statement that all dogs in Maine need Lyme vaccine!
