my son 7 yrs 5 months. He got a scratch from a pet dog .the owner told that the dog is already vaccinated. The scratch didn't tear the skin and there was no blood. but there was 3 red scratch marks on his hand. I didn't want to take risk and I have already given him 3 rabies injection...Now my question is have I done wrong by giving him the vaccine and did his immunity power will be affected by the vaccine given
