Hello Doctor, I Have received post exposure anti rabies vaccination in January 2016 around 11 months from today. And Yesterday a stray dog again pinched my knee with his teeth. Wound is very tiny. Do I need to get vaccination again? Please also give quotes about the validity of the vaccination. Thanks.
Hi,1. Since you have completed the earlier post exposure regime in January 2006 and the duration of immunity afforded to humans by the course was found to be between two and three years, and if one is working/living in a high risk environment, the British NHS recommends a booster shot one year after the last shot, and after that every three to five years intervals.2. If someone has been bitten by the dog [in between], only two doses of anti rabies Vaccine are to be given on day 0 and 3, whatever is the interval from primary vaccination. Hope I have answered your query. Let me know if I can assist you further.
