Hello Doctor, Please read my question carefully. I took rabies booster dose from a governed medical. The syringe was already loaded with vaccines. Vaccines are kept in a plastic container with one ice packet. Container was moist. I saw one used syringe was also there. But no needle connected. My question is if that syringe was used for someone. How much risk for hiv? As they didn't use the same syringe to me. They given a already vaccine loaded syringe to me. My concern is if the used syringe contains blood and mixed with moisture. As the container was with a icepack. If those blood mixed moisture touch my syringe needle. Any chance for infection? I am very much worried. Please help.
