CORE VACCINES VERSUS NON CORE VACCINES
The core vaccines include parvovirus, distemper, adenovirus (canine hepatitis) and rabies. These vaccines all protect against viruses, which are easy to protect dogs against. In fact, viral vaccines are so effective that, when given to a dog over four months of age, they’ve been scientifically proven to protect that dog for years, and most likely for life!
The non-core vaccines aren’t included in this group for three main reasons: They don’t work as well, They don’t protect for very long and They’re more dangerous
Let’s look at the non-core vaccines and the issues surrounding them. Here is the first one, others will follow in subsequent posts.
The majority of dogs with known leptospirosis have been found to be without symptoms – they live with it without getting ill.
This isn’t to say that leptospirosis can’t cause illness in dogs. In some cases lepto can be fatal.
However, in the 1996 Canine Health Concern vaccine survey 100% of dogs with leptospirosis had been vaccinated within three months prior to infection. This can only be because:
The vaccine caused the disease, or
The vaccine didn’t contain the serovar that caused the illness, or
The vaccine contained a non-local serovar that the dog hadn’t adapted to, or it just didn’t work.
If your vet recommends a lepto shot, you need to ask him two questions. The first is whether he has seen a case of lepto in the last, say, six months (i.e., is the vaccine necessary?). The second is which serovar is involved, and is that serovar in the vaccine? For if it’s not, the vaccine won’t help. There are over 200 versions of leptospirosis and vaccination against one form will not provide protection against the others. The lepto virus does NOT protect 1/3 of all dogs.
Scientists have been trying to develop a human leptospirosis vaccine for decades – one that’s safe and effective and which governments will license around the world. They have failed.
But a dangerous, ineffective, substandard canine vaccine is out there, and will remain out there until pet owners educate themselves of the risks.
What is the leptospirosis vaccine doing on the WSAVA non-core list? It has no place there. It should be on the “not recommended” list. Leptospirosis is not even a vaccinatable disease, and the vaccine can kill!
