My friend was bitten by a dog on his hand 5 years ago but didnt get a rabies vaccination.She also dont know if the dog died or if it remained alive. Last June 2017, ahe we t to an animal bite treatment center and they give him only pre exposure treatment for 3 doses. Dissatisfied, August 2017,she went to another treatment center, and they advised him to undergo the full course session of post exposure treatment which is 4 doses(0,3,7,28)2 shots each session. A month after he finished his Day 28... her wound was licked by a cat and she received again booster(2 doses) Was his treatment enough or did i receive too much anti rabies vaccine in his body? Do we need to worry?thanks so much
