hello, my son was a 3 year old now, then got bitten with the dog when he was a 2year old, then when we go for the vaccination after 2weeks, the doctor ask me the condition of the dog, then i told that the dog was ok, then he said that nothing 2 worry because the dog was ok and then he did not gave vaccoine to ny son,but this time i was wondering if my son still need a vacination after one year?
