Last year on June I took 3 doses of rabies vaccine each after 4 days interval. On October I took 1 more dose as booster. Both the time I was bitten by a pet dog who is vaccinated and alive. Today I got bitten on my sole of foot. There was no bleeding but there is swelling and little pain and don't know whether there is tear in skin. I was bitten by a vaccinated dog but the dog interacts with other street dog. Please tell do I need to take vaccination again if so then will it be safe like would it cause overdose or something??
