Here are my mixed thoughts on vaccinations...
There is a strong documented link between the former flu shots and the hight rate of autism in children. They changed that shot, but still.
We are losing herd immunity. In people we have very little natural immunity to small pox, it is now considered a 'good' bio terror weapon for that reason.
I know of a litter where one pup, do to its future owner did not get ANY shots. The whole litter got parvo (for get if they ever figured out how they litter got exposed), the one who was the least sick was the one with out the vaccination. Now I am not saying its not because of the lack of getting the shot, just saying it makes me question the efficacy of the shot.
With horses west nile is very dangerous issue, and horses are often immunized multiple times a year to protect them. Horses who have gotten the shot 4 times a year still get it and die, and its shown signs of being teratogenic. (caused birth defects)
My dogs do get shots though. I will only do vaccinations that are going to give them a clear benefit if they are exposed to the disease. If its a disease that mutates rapidly, then I don't bother. Same with me and my family, we don't do the flu shot, but we do get tetanus.
I am not a fan of poisoning my dog but when Dekka and Snip were doing some hunting they were on Advantage. When we go out hunting again, they will be on it again.
