Marci (Marcerella02) found this vet's blog a few weeks back and I'm just LOVING it. Anyway, this vet is just wonderful in terms of vaccines. She mentioned using a 3-in-1 vaccine only, which I could not source anywhere - so I emailed her and Dr. Terifaj replied with this:
"Intervet makes
Continuum DAP which is being marketed as the only 3 year USDA approved vaccine. It is pricey compared to the vaccines most vets are using. However, we know that the old standby vaccines (vaccine titers have proved this) can also provide a long duration of immunity---3 years or longer! So, in my opinion the only reason to pay more for this vaccine is if you are determined to use a 3 in 1 combo."
Here is her wonderful blog, which I subscribe to - and you can get her great newsletters too:

So, in thinking through this 3-in-1, I
think the only real application here is if you want to avoid the DA2PP because you think the parainfluenza vax is unnecessary (which some are saying). Otherwise, we should get the same longevity from the old vaccines (and less cost). Is that your impression as well?
