I was giving a varicella vaccine on a 12 month old at an office I work at. He was a newer patient so we didn't have any of his screenings. His history said healthy with no issues but I can't be for sure of that can it? My supervisor was watching me for a check off and he didn't see it. It was after I injected it and went to put flip the safety. It got me pretty good like it bled and left a small bruise. I immediately washed my hands and scrubbbed my finger with alcohol. I didn't tell anyone about it either as I am Very new. I'm so embarrassed and worried. I feel even more stupid now for not telling anyone. He shouldn't have any blood borne pathogens, I wouldn't think 😫But I don't know 100% for sure!
