How long do dog hepatitis and parainfluenza vaccines truly last?

Question

Hi. Can you tell me how long the Adenovirus (Hepatitis) and Parainfluenza vaccines can last in a dog? My vet doesn't offer titre testing for these 2 like they do for Distemper and Parvovirus, but I do not want to over vaccinate. Thank you. Pet's info: Dog | Boxer | 7 years and 9 months old

Hi there! It's hard to say honestly without titer testing how any dog's immune system is functioning. However, I can provide you with some additional information based on how we vaccinate where I practice. We administer the DHPP (distemper-hepatitis-parainfluenza-parvo) vaccine in a booster series as puppies. After the final booster is given, it lasts a year. At that 1 year mark, we will do a 3 year booster for this vaccine. However, in a lecture I attended this past fall, the speaker brought up the fact that without testing, we don't know if the titers are lasting those 3 years, less than that, or even longer in some cases. The only way to know is to evaluate the dog's immunity. Having a conversation with your veterinarian in this situation is key. They may be vaccinating because of the diseases being more prevalent in your area, so I'd double check that. If not, perhaps they would be comfortable moving your booster out for longer stretches of time. This will depend on the manufacturer of the vaccine as well as your vet's recommendations. If the brand of vaccine they use is not labeled to go out that long without a booster, then the vet may not be able to do it. Another option, which I offer to my clients who are concerned about this same issue, is a referral to a holistic veterinarian who may be able to do the titer testing for you. I again would definitely have a conversation with your vet. I always welcome my clients to discuss anything at all that may make them feel uneasy as we go along. . I'm sure that Cruz's vet feels the same. I hope though, that I have provided some useful information for you in the meantime. Best of luck!
