A friend from another forum works at a vet hospital and said they recently changed to every 5 years instead of every 3.
It's a start...
Basically, this is not "new" news as the AAHA DOI studies already state 7 years to a lifetime for DHP, and that 5 years is protective.
In AAHA 2011 it mentions every 5 years as acceptable. I don't remember if earlier editions stated the same. If I had to guess, they probably just switched from annual to every 3 years when a lot of other AAHA hospitals did the same. But AAHA did not set every 3 years in stone. It was a compromise, So is every 5 years. Then perhaps recently one of the owners of the hospital dug a bit deeper.
Since 5 years is still a random compromise (very safe). Most offices will stick to every 3 (or annually which is ridiculous). Some might get really brave and do it every 7-9 based on the studies. Hopefully vets will start to be open to doing it less often.
Owner and I were talking today and the bottom line for him is that the decision to vaccinate should not be a monetary one. And if we are jabbing every three years when there is a ton of evidence that this is still too often, then (in this office's case based on what they see scientifically) we are doing it for monetary gain. The vets here never ever make decisions based on what makes them the most money.
It is still not within some vets' comfort levels to do it less often, but at sone point they need to move ahead with the times (esp.annual vaccinators). Because minimum DOI is 7 years it is safe to assume every 5 is still being very cautious. Maybe they will move to every 7 years in the future.
Just thought I would pass on.
To me, it doesn't matter what AAHA says anyway, I don't really plan on vaccinating Jackson again for DHP, but for those who feel they need a 'schedule' to follow -- this is good news.
