The vaccine debate is a slippery slope. I've had 3 of my own personal dogs go through AIHA. Once they have that - IF they survive, I do not vaccinate them any more, with the one exception being the 3 yr rabies required by our state.
Apparently some breeds are more prone to the auto-immune problem.
I do my best to keep them up on vaccines, but at the same time don't want to over load their immune system and throw them into AIHA. All we can do is educate ourselves and make the best choices for our pets, that we can with the info available.
It's a personal choice issue and we all have to live with the consequences of our own decisions.
