• Hepatitis B
  • For Adults (Including HBV Screening)

At what anatomic site should hepatitis B vaccine be administered to adults? What needle size should be used?

The deltoid muscle is recommended for routine intramuscular (IM) vaccination among adults. The anterolateral thigh also can be used. The gluteus muscle should not be used as a site for administering HepB. Please refer to the Immunize.org document Administering Vaccines to Adults: Dose, Route, Site, and Needle Size (available at www.immunize.org/catg.d/p3084.pdf) for complete information on this issue.
