January, there was an exposure from a dog, although it was an Indian breed dog from our own house. A similar incident happened again in March. At that time also, out of fear, I took two booster doses. According to WHO there is protection for up to 3 months. Even after knowing that, I still took the boosters out of fear on the 5th and 8th according to CDC Yesterday, on 21st May, there was another exposure and there is a slight scratch on the skin. On 8th June, the 3-month period will end. After that, if I take another booster for , will it be harmful? I have heard that taking boosters again and again can cause many side effects. Is taking 5 ARV doses and 3 booster doses (total 8 rabies vaccine doses within 6 months safe)? Or can it cause autoimmune diseases? What should I do now?
