Be aware -- this isn't just a difference in what's in the shot or "annual" or "three-year". The DHLLP is a 'killed' vaccine -- that means it's made out of killed disease cells and, as a result, it gives less long-lasting protection. That's what originally gave rise to the whole 'annual' vaccine thing -- BECAUSE they knew it didn't last as long and generally they last less than a year ... which is where the "twice a year" idea came from that many vets tried to do.
The "new" protocol is a cocktail of three modified live- or recombitant vaccines. Distemper, parvo and adenovirus. I *think* it's the distemper one that is the recombitant vax (which really kinda rocks -- it's extremely safe because it's not the whole 'disease' cell but simply has some of the genetic material withdrawn so it's not the entire disease cell so it can't replicate as the disease). They don't *have* one for parvo yet ... but it's coming.
However ... these vax (which they are now referring to as "core vaccines";) are far far superior to the annual "killed" vax. BUT the true kicker is, that they last for far far ***longer*** than just 3 years. Three years is what they have "tested, studied, proof' for. But honestly -- if you simply titer after that it's very likely you'll never need to vaccinate again IF that core vax was given to the dog as an adult.
I hate to see people just never bother going back to the vet -- that's not the intent of what I'm saying. Go ahead and get the titer done and you'll have a darned good idea of how good your dog's immunity is.
Last year Kee titered low on parvo and Luna titered low on distemper -- so they both got a round of the core vax this one time. Thereafter we'll titer. Tink got her core vax when she came to us and I'll do another set this summer (vax stresses demodex so much I wanted to wait until the immune system was stronger and I do all that kind of thing in August). Billy, as most of you know, can never be vax'd again -- I even get a waiver from the State for him on his rabies (literally any vaccine would likely kill him).
But just be aware -- it's not the diseases that are covered that makes the huge difference -- it's the difference between a "killed" vax and a "modified live" or "recombitant" vax that makes the difference in the length of time they are good for.
As someone pointed out above -- rabies vax are ALWAYS modified live vaccines. There is no such thing as a 'killed' rabies vax.
