Universal hepatitis B vaccination in adults aged 19–59 years: Updated recommendations of the advisory committee on immunization practices—United States, 2022

Abstract

This article describes updates to the recommendations for hepatitis B vaccination in the US. Most notably, the Advisory Committee on Immunization Practices (ACIP) now recommends universal hepatitis B vaccination for all adults (without a history of hepatitis B infection) aged 19-59 years, as well as those 60 and older with known risk factors for hepatitis B such as liver disease. Thus, all transplant candidates and recipients aged 19-59 years, and all adult liver transplant candidates regardless of age, should be vaccinated for hepatitis B. Universal hepatitis B vaccination is already recommended for children. This article describes updates to the recommendations for hepatitis B vaccination in the US.

Hepatitis B is a vaccine-preventable, communicable disease of the liver caused by HBV. HBV is transmitted through percutaneous (i.e., puncture through the skin) or mucosal (i.e., direct contact with mucous membranes) exposure to infectious blood or body fluids. Since HepB vaccine was introduced in 1982, the number of reported hepatitis B cases has declined substantially. However, despite reductions in hepatitis B incidence during the past 4 decades, which were achieved through incremental expansion of groups for whom HepB vaccination is recommended, progress in recent years on further reducing acute hepatitis B cases has stalled.3CDC.

The Work Group identified the following outcomes of interest for evaluation: incidence of hepatitis B, morbidity related to hepatitis B, mortality related to hepatitis B, and vaccine-related serious adverse events. Data on universal HepB vaccination outcomes and safety were summarized based on findings from a systematic review of the literature completed on September 10, 2020, and updated September 20, 2021. The Work Group assessed the certainty of evidence at the outcome level related to the U.S.-licensed HepB vaccines for all adults previously unvaccinated against HBV infection, using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Detailed descriptions of methods and results are available in the GRADE evidence profile (https://www.cdc.gov/vaccines/acip/recs/grade/hepb-adults.html).Afterthe GRADE assessment, decisions were made using the Evidence to Recommendation (EtR) Framework (https://www.cdc.gov/vaccines/acip/recs/grade/hepb-adults-etr.html). During July 2021–February 2022, the Work Group participated in three conference calls to review the evidence for the seroprotection and safety of PreHevbrio, a three-antigen 3-dose HepB vaccine newly approved by the Food and Drug Administration (FDA) in 2021. Description of the methods and results are available for the GRADE evidence (https://www.cdc.gov/vaccines/acip/recs/grade/prehevbrio-hepb.html) and EtR Framework (https://www.cdc.gov/vaccines/acip/recs/grade/prehevbrio-hepb-etr.html). The scientific literature was searched through a systematic review using PubMed, Medline, Embase, CINAHL, and Cochrane Library databases from January 1, 2006, through September 10, 2020. Search terms included “hepatitis b vaccines,” “adult,” “routine,” and “universal.” To qualify as a candidate for inclusion in the review, a study had to discuss adult HepB vaccination. Studies were excluded if they did not address the adult population, were non-English language, discussed HepB vaccines not licensed in the United States, or if data could not be abstracted. The search identified 3226 studies, 263 of which were deemed eligible and informed this review. Rates of reported acute hepatitis B have not notably decreased for over 1 decade, with 20 700 estimated infections in 2019.3CDC. Viral hepatitis. 2019 viral hepatitis surveillance report.

Vaccination with hepatitis B (HepB) vaccines shows well-established safety and efficacy. However, because of risk factor−based approaches of previous vaccination recommendations, coverage among adults has been suboptimal. In addition to groups for whom HepB vaccination is already recommended, the Advisory Committee on Immunization Practices recommends that all adults aged 19–59 years should receive HepB vaccines. Universal adult HepB vaccination through age 59 years removes the need for risk factor screening and disclosure and could increase vaccination coverage and decrease hepatitis B cases. Approximately one half of acute hepatitis B cases reported in 2019 occurred among persons aged 30–49 years (Figure 1). The number of cases of acute hepatitis B has increased among adults aged ≥40 years, particularly among those aged 40–49 years, for whom the rate of reported cases increased from 1.9 per 100 000 population in 2011 to 2.7 per 100 000 population in 2019 (Figure 1). The rate among adults aged 50–59 years increased 45.5% during the same period (from 1.1 to 1.6 per 100 000 population) and accounted for 22.2% of reported cases in 2019. Acute HBV infections among adults leads to chronic hepatitis B disease in an estimated 2%–6% of cases. HepB vaccination coverage among adults aged ≥19 years is low. In 2018, self-reported HepB vaccination coverage (≥3 doses) among adults aged ≥19 years was 30.0%.7Lu PJ Hung MC Srivastav A et al.Surveillance of vaccination coverage among adult populations—United States, 2018.MMWR Surveill Summ. 2021; 70 (doi:10.15585/mmwr.ss7003a1): 1-26Crossref PubMed Scopus (72) Google Scholar HepB vaccination coverage (≥3 doses) was 40.3% for adults aged 19–49 years and 19.1% for adults aged ≥50 years. During 2013–2018, 21.4% (95% CI = 20.2%–22.6%) of adults aged ≥25 years had vaccine-induced immunity to hepatitis B.5Roberts H Ly KN Yin S Hughes E Teshale E Jiles R.

HepB vaccination is recommended for adults aged 19–59 years and adults aged ≥60 years with risk factors for hepatitis B. Adults aged ≥60 years without known risk factors for hepatitis B may also receive HepB vaccines (Box 1).

Adults aged ≥60 years without known risk factors for hepatitis B may receive hepatitis B vaccines. Abbreviation: HBsAg, hepatitis B surface antigen ACIP recommends that adults aged 19–59 years and adults aged ≥60 years with risk factors for hepatitis B should receive HepB vaccines, and that adults aged ≥60 years without known risk factors for hepatitis B may receive HepB vaccines. In previous HepB vaccine recommendations, providers were advised to administer HepB vaccine to all patients who requested it. The new language for adults aged ≥60 years without known risk factors is intended to prompt all providers to offer HepB vaccination to patients in that cohort, rather than wait for a patient to request vaccination, thus shifting the responsibility of initiating the consideration of HepB vaccination from the patient to the provider. Persons who have completed a HepB vaccination series at any point or who have a history of HBV infection should not receive additional HepB vaccination, although there is no evidence that receiving additional vaccine doses is harmful.¶ However, there are cases where revaccination might be indicated as specified in the 2018 ACIP recommendation (e.g., nonresponder infants born to persons testing positive for hepatitis B surface antigen [HBsAg], health care providers, and persons on hemodialysis).2Schillie S Vellozzi C Reingold A et al.Prevention of hepatitis B virus infection in the United States: recommendations of the Advisory Committee on Immunization Practices.MMWR Recomm Rep. 2018; 67 (doi:10.15585/mmwr.rr6701a1): 1-31Crossref PubMed Scopus (362) Google Scholar Providers should only accept dated records as evidence of HepB vaccination. Vaccination of persons immune to HBV infection because of current or previous infection or HepB vaccination does not increase the risk for adverse events. However, in settings in which the patient population has a high rate of previous HBV infection,**** prevaccination testing, which may be performed concomitantly with administration of the first dose of vaccine, might reduce costs by avoiding complete vaccination of persons who are already immune. Prevaccination testing consists of testing for HBsAg, antibody to HBsAg (anti-HBs), and antibody to hepatitis B core antigen (anti-HBc). The presence of HBsAg indicates current HBV infection. The presence of anti-HBs is generally interpreted as indicating immunity, either from HepB vaccination after a complete series or after recovery from HBV infection. The presence of total anti-HBc indicates previous or ongoing infection with HBV. Detailed interpretations of serologic markers for HBV infection are available.2Schillie S Vellozzi C Reingold A et al.Prevention of hepatitis B virus infection in the United States: recommendations of the Advisory Committee on Immunization Practices.MMWR Recomm Rep. 2018; 67 (doi:10.15585/mmwr.rr6701a1): 1-31Crossref PubMed Scopus (362) Google Scholar Lack of access to serologic testing should not be a barrier to vaccination of susceptible persons, especially in populations that are difficult to reach.

If a 3-dose series is interrupted after the first dose, the second dose should be administered as soon as possible; the second and third doses should be separated by an interval of ≥8 weeks. If only the third dose has been delayed, it should be administered as soon as possible. The final dose of a 3-dose series must be administered ≥8 weeks after the second dose and ≥ 16 weeks after the first dose; the minimum interval between the first and second doses is 4 weeks. Inadequate doses of hepatitis B vaccine or doses received after a shorter-than-recommended dosing interval should be readministered, using the correct dosage or schedule. Vaccine doses administered ≤4 days before the minimum interval or age are considered valid. Because of the unique accelerated schedule for Twinrix (https://www.fda.gov/media/119351/downloadexternalicon), the 4-day guideline does not apply to the first 3 doses of this vaccine when administered on a 0-day, 7-day, 21–30-day, and 12-month schedule.

ACIP is chartered as a federal advisory committee to provide expert external advice and guidance to the CDC Director on use of vaccines and related agents for the control of vaccine-preventable diseases in the civilian U.S. population. Recommendations for routine use of vaccines in children and adolescents are harmonized to the greatest extent possible with recommendations made by the American Academy of Pediatrics, the American Academy of Family Physicians (AAFP), and the American College of Obstetricians and Gynecologists (ACOG). Recommendations for routine use of vaccines in adults are harmonized with the recommendations of AAFP, ACOG, and the American College of Physicians. ACIP recommendations approved by the CDC Director become agency guidelines on the date published in the Morbidity and Mortality Weekly Report. https://www.cdc.gov/vaccines/acip † The ACIP Hepatitis Vaccines Work Group comprises professionals from academic medicine (family medicine, internal medicine, pediatrics, obstetrics, infectious disease, occupational health, and preventive medicine specialists), federal and state public health entities, and medical societies. § https://www.cdc.gov/vaccines/acip/meetings/downloads/slides-2021-11-2-3/02-HepWG-weng-508.pdfpdficon ¶ https://www.cdc.gov/vaccines/hcp/acip-recs/general-recs/index.html ** https://cdafound.org/polaris/externalicon (Accessed November 19, 2021).
