The carefully documented leukemia

«However, sometimes it doesn't work — as in the

I reported the failure and serious side effects of the feline vaccine in the January 1981 issue of The Dog newspaper, thus becoming the first dog fancy journalist to report

In puppies the immune system must learn how to function and
vaccine failure in a young puppy may occur simply because the puppy's immune system didn't know how to react properly (the reason multiple doses of some vaccines are given.)

Those who do vaccinate must accept the risks of side effects, allergic reactions,

This would be the best use of a titer test as a negative titer would now have predictive value, meaning there was either
