unfortunately the drug companies have brainwashed the vets, policy makers, and public about vaccines effectiveness.

i believe there's not much difference in pet and human vaccines. addictives and perservatives used in vaccines like aluminum, formaldehyde, thimerosal, monosodium L-glutamate (MSG), aspartame, and etc. are not ingredients i want in my body nor my pets' bodies. also i don't want to pollute my body with chick embryos or embryonic fluid or cells from aborted fetal tissue and etc. think the flu vaccine works? heehee
