Here is some info regarding vaccine research for Foot and Mouth disease. It's quite contagious and deadly. Although it has nothing to do with dogs,
it's an interesting read.

"We can grow the virus in tissue culture, and this particular protein stays behind in the culture cells when you extract the virus," explains
Brown. "So you can make a vaccine from that virus, inject it into livestock, and the animals' immune systems won't make antibodies against that
particular protein because it wasn't present in the vaccine.
"But if an animal has been infected with FMD virus, that protein will have been present, and you will find antibodies against it in the blood. So, to
differentiate between an animal that's been vaccinated and one that was actually infected with FMD virus, you could run tests to check for antibodies
against that indicator protein."
Brown and fellow ARS microbiologist John F.E. Newman are also looking at the creation of a vaccine that uses only a string of some 20 amino acids from
the virus—just enough of a taste of the virus to jump-start the injected animal's immune system into producing enough antibodies to neutralize the
virus. This prototype vaccine has effectively protected cattle against FMD in field tests in Argentina, Brown says.

Here is some good Q&A from a vet regarding vaccines:
www.homeovet.net...
The purpose of vaccination is to protect your pet from potentially fatal infections by pathogenic (disease-causing) viruses such as distemper,
rabies, and others. The way this is done is to inject either a killed virus or a 'modified' (non-pathogenic) live virus, which sensitizes the immune
system to that particular virus. Thereafter, if your dog is exposed to, let's say, parvovirus, s/he will be able to respond quickly and vigorously,
producing antibodies to overcome the infection.
He goes on to say this:
In summary, there is a great deal of evidence implicating vaccination as the cause of many serious chronic health problems. For this reason, I do
not recommend vaccination for dogs or cats.
In particular, I strongly recommend against vaccination for Feline Leukemia in cats, because (a) it is not very effective, and (b) I have found
that vaccinated cats that subsequently contract the virus are much more likely to die from it. I also recommend against vaccination for Lyme disease
and kennel cough in dogs, again due to lack of effectiveness, and the fact that these conditions are generally not very serious. As such, the
potential harm of the vaccine is not justified.
In all fairness, the choice to forgo vaccination for your pets does carry some risk. Your puppy could contract parvovirus, for instance, which
that particular vaccine is effective in preventing. Fortunately, parvo is generally quite easy to treat homeopathically. Distemper and infectious
hepatitis are rarely seen anymore.
So, in conclusion, some vaccines should be administered, while others can be a gamble. It's all up to the owner to decide, but parvo is recommended
even by those vets who are against vaccines.
This sounds like a pretty good plan, on the surface. However, as with any medical procedure, we must ask the simple and direct questions, Is it
safe? Is it effective? Do the benefits outweigh the risks?
