Hi . Your concerns are certainly understandable. I need to note that we are not medical professionals and, for your protection, cannot offer medical advice over the internet. I can offer this article from our editorial team on differences in HIV transmission risk, which includes accidental needle stick: https://h-i-v.net/transmission-risks. Of course, every situation is different and the risk can change due to issue circumstances. I can't personally speak to PEP, but this article gives an overview: https://h-i-v.net/pep. It does note that one of the instances it may be advised for is an accidental needle stick in a medical setting. I can't speak to your precise circumstance. I hope this information is helpful.
