Technically Speaking
Monthly Column by Deborah Wexler, MD
Deborah Wexler MD
Technically Speaking is a monthly column written by IAC’s Executive Director Deborah Wexler, MD. The column is featured in The Children's Hospital of Philadelphia Vaccine Education Center’s (VEC's) monthly e-newsletter for healthcare professionals. Technically Speaking columns cover practical topics in immunization delivery such as needle length, vaccine administration, cold chain, and immunization schedules.
Check out a recent issue of Vaccine Update for Healthcare Providers. The VEC e-newsletter keeps providers up to date on vaccine-related issues and includes reviews of recently published journal articles, media recaps, announcements about new resources, and a regularly updated calendar of events.

Hepatitis B Vaccination for Adults — Who Needs It and When?
Published October 2016
Hepatitis B vaccination recommendations vary by a person’s age and risk factors. In the Technically Speaking column in August, we discussed routine hepatitis B vaccination of infants, children and teens. This month, let’s review hepatitis B vaccination of adults, including vaccination guidance for high-risk groups. In an upcoming column, we will review the issues surrounding hepatitis B serologic tests and vaccination, including who needs testing and when.
 

Routine administration schedule for hepatitis B vaccine in adults

  • The dosing schedule is 0, 1 to 2 months, and 4 to 6 months.
  • There is some flexibility in the schedule, but be sure to keep in mind the minimum intervals between doses:
    • At least four weeks between doses #1 and #2
    • At least eight weeks between doses #2 and #3
    • At least 16 weeks between doses #1 and #3
  • If your patient falls behind on the hepatitis B vaccination schedule (even if a year or more has elapsed), continue vaccinating from where your patient left off. The series does NOT need to be restarted.

Recommended adult dosing volume of monovalent hepatitis B vaccine

  • Age 19 years and younger: Use 0.5 mL per dose (Engerix®-B pediatric, GlaxoSmithKline; Recombivax HB® pediatric, Merck).
  • Age 20 years and older: 1.0 mL per dose (Engerix-B adult, GlaxoSmithKline; Recombivax HB adult, Merck). (For dialysis patients, a larger dose is needed. See the prescribing information.)

For a one-page sheet reviewing the hepatitis B dosing schedule for children and adults, consult IAC’s Hepatitis A and B Vaccines: Be Sure Your Patients Get the Correct Dose. For complete dosing information, consult the ACIP hepatitis B vaccine recommendations for adults.

Which adults should be vaccinated against hepatitis B?

According to CDC recommendations, adults in the following groups are recommended to receive hepatitis B vaccine:

General

  • All people age 18 years and younger. (CDC includes 18-year-olds in their child/teen immunization recommendations.)
  • Anyone 19 years and older who wants to be protected from hepatitis B.

People at risk for infection by sexual exposure

  • Sex partners of people who are hepatitis B surface antigen (HBsAg)-positive.
  • Sexually active people who are not in long-term, mutually monogamous relationships.
  • People seeking evaluation or treatment for a sexually transmitted disease.
  • Men who have sex with men.

People at risk for infection by percutaneous or permucosal exposure to blood or body fluids

  • Current or recent illegal injection drug users.
  • Household contacts of people who are HBsAg-positive.
  • Residents and staff of facilities for developmentally challenged people.
  • Healthcare and public safety workers with reasonably anticipated risk for exposure to blood or blood-contaminated body fluids.
  • People with end-stage renal disease, including predialysis, hemo-, peritoneal- and home-dialysis patients.

Others

  • International travelers to regions with intermediate or high levels of endemic HBV infection.
  • People with chronic liver disease.
  • People with HIV infection.
  • People with diabetes who are age 19 through 59 years. For those age 60 and older, clinicians should make a determination of need for
  • vaccination based on their patients' situation.

According to ACIP recommendations, patients do not need to identify (or admit to) a particular risk factor in order to be eligible for vaccination. Anyone who wishes to be protected from hepatitis B should be vaccinated.

Some patients (e.g., foreign-born persons from regions with medium or high levels of HBV infection) are recommended to have their blood tested for evidence of past or present hepatitis B virus infection at the same time that they receive the first dose of hepatitis B vaccine. Blood testing should be done at the same visit as administering the first dose of hepatitis B vaccine. Blood should be drawn prior to hepatitis B vaccine being administered.

In a future issue, we will review the various hepatitis B serologic tests, who needs testing, and when they need it (pre- or post-vaccination).
