Do I really need to vaccinate my dog every year?

Recent research indicates that not all vaccines require yearly boosters. There is no evidence that annual booster vaccination is anything but beneficial to most dogs. Published research has shown conclusively that abstaining from some boosters can put your dog at risk. For dogs with low-risk lifestyles or whose owners prefer less frequent vaccination, your veterinarian may recommend giving your dog certain core or essential viral vaccines on a three-year schedule. Recent studies have demonstrated that some viral vaccines may convey at least three years of immunity. This is not the case with bacterial vaccines, which usually still require annual boosters. Ultimately, your dog's lifestyle and relative risk determine how frequently your dog should be vaccinated. You and your veterinarian should decide which vaccinations your dog will receive based on your dog’s lifestyle, age, and health status. If you regularly board your dog or if he is exposed to other dogs, some vaccines, especially those for infectious bacterial diseases such as kennel cough (Bordetella), may be needed annually.

Veterinarians have suspected for years that annual vaccinations for cats and dogs aren’t necessary, but large, well-controlled studies just didn’t exist to prove it one way or the other. With the exception of rabies vaccine, the U.S. Department of Agriculture doesn’t require data beyond one year for any vaccine. Sometimes immunity lasts a lifetime. We know that for distemper and parvo, for example, the immunity lasts a minimum of five years, probably seven to nine years, and for some individuals for a lifetime. For cats, so far we have challenge data out nine years showing that immunity is still protective. Annual boosters for the core vaccinations are excessive for most dogs and cats. Limited studies suggest that booster vaccinations for many of the core vaccinations last for at least seven years. However, given the limited number of animals involved in these studies, three years seemed like a reasonable compromise.

The WSAVA publishes general guidelines on vaccination protocols designed for vets across the world to use – they’re not definitive rules, set in stone. They are really useful, but they need to be interpreted in light of local conditions in the UK, because what vaccines are needed here aren’t necessarily the same as those needed in California, or Siberia, or Uganda. How long the vaccines last depends on the vaccine and on the vaccine’s license, however, vaccines don’t last forever – eventually their effectiveness and therefore the protection they offer declines. As a rule of thumb: Distemper, Parvovirus, Hepatitis and Rabies vaccines last 3 years. Leptospirosis, Parainfluenza, Bordetella, Lyme Disease and Leishmania vaccines last only one year. So, you can see where the confusion has come from – because the WSAVA regards Lepto as “non-Core”, they have said that dogs only need vaccinating every 3 years, however, in the UK, Lepto is so important that it needs to be kept up to date – meaning our dogs need annual vaccination. The other complication is the legal situation – vets are, generally, legally obliged to use medications (including vaccines) in accordance with the manufacturer’s guidelines. If the manufacturer cannot prove that the vaccine lasts the full 3 years, it doesn’t matter what the WSAVA say – it’s irresponsible for us to recommend you only vaccinate every 3 years, as we could be leaving your dog unprotected.

We know that the core vaccine lasts for at least 3 years, but can last much longer, up to the life time of the dog. But we don’t know for which dogs it lasts longer and for how long, so to be on the safe side, we vaccinate against these diseases every 3 years. It has always been possible to check whether a dog is still protected against the core diseases, but it was so expensive that only very few people had it done. These days though, titre testing is much more affordable, and in my mind really is the obvious thing to do. Titre testing is a blood test that will tell you if your dog still has immunity against the core diseases: Distemper, Hepatitis and Parvo. So this is how it could work: Full puppy course and first booster, then small vaccine at year 2 and 3, then in year 4, rather than giving the full vaccine again, run a titre test, and only give the vaccine if needed. But do vaccinate against Lepto every year. A positive titre test means your dog is protected for at least 1 year, and it’s recommended to then titre test every year to be sure the cover still lasts.

Many owners believe that once their dog has had their initial round of vaccinations, they’re protected for life. Unfortunately, this isn’t true. Annual booster vaccinations are needed throughout your dog’s life to maintain their protection from harmful disease. Some boosters are required every year, while others are needed every three years; this is because the protection they offer becomes less effective over time. The booster vaccinations dogs require are: Boosters for distemper, parvovirus and canine hepatitis every three years Boosters for leptospirosis and kennel cough every year. Older dogs still need regular booster vaccinations to protect them from potentially fatal diseases, particularly as their immune system can weaken as they get older. Your vet will be able to assess the individual needs of your pet based on their age, overall health and lifestyle to ensure they receive the right vaccinations.
