Well, I couldn't live with my twisting stomach anymore about it so I asked a vet tech at the hospital and they said they have two safety procedures they follow for labeling. One is that they leave the sticker for the vaccine on the needle until after it is administered and then they transfer it to the pet's record sheet. I know there were already two stickers on the paper, but I think each vaccine comes with two stickers, so there are four stickers that eventually go on the sheet once both vaccines are administered. The second safety measure they have is to put an R with marker on the end of the Rabies syringe. So now I can sleep better tonight knowing my dog is properly protected for parvo and distemper
