After drawing blood from a woman with a known history of intravenous drug abuse, 23-year-old male nursing aide at the local free clinic accidentally pricks his finger with the needle. According to the patient’s record, she has not received any immunizations in
the past twenty years and recently tested positive for HBsAg. The nurse has no significant medical history and takes no medications. Several months ago, he received a second series of three HBV vaccines and shortly afterward, his titer was found to be < 10
mIU/mL (>10 mIU/mL is considered adequate). What is the most appropriate means of handling this situation?

Re: hbv kaptest100 - 05-07-10 22:22 Hep B PEP
If the source patient is HBsAg positive and the exposed person is unvaccinated, HBIG ASAP after exposure (preferably within 24 hours) + the vaccine series started.
If the exposed person had an adequate antibody response (>10 mIU/mL) documented after completion of an HBV vaccination series=no testing or treatment is needed
Hep C PEP
Currently, there is no proven effective post exposure prophylaxis for persons exposed to HCV blood or contaminated body fluids.
CDC recommends that persons exposed to an HCV-positive source have the following baseline and follow-up testing
Baseline testing for anti-HCV, HCV RNA, and alanine aminotransferase (ALT)
Follow-up testing for HCV RNA between four and six weeks after exposure
Follow-up testing for anti-HCV, HCV RNA, and ALT between four and six months after exposure
