Hepatitis B Vaccination, Screening, and Testing – Three Things You Have to Know

1. Hepatitis B Vaccine for ALL 0 to 59 Years of Age
Hepatitis B Vaccine, HepB, will become a universal vaccine for children and adults in 2022. This means that all populations up to 59 years of age should
complete the HepB series at any stage of life. If your HepB series needs to be completed or the vaccination status needs to be discovered, please talk to your healthcare
provider or visit Imperial County Immunization Clinic or any pharmacy.

Hepatitis B Vaccine: What You Need to Know

2. One-Time Hepatitis B Screening for ALL 18 Years of Age and Over
A new recommendation announced in 2023 by CDC advises that all adults
18 years of age and over have hepatitis B screening at least once a life. The most crucial rationale is to detect chronic hepatitis B early, which is
asymptomatic, transmittable, and not curable compared with acute hepatitis B, and to start antiviral treatment as soon as possible to prevent
complications such as liver cirrhosis, liver cancer, or liver transplant. In the United States, prevalence of chronic hepatitis B is low at less than
2%. However, some of our LGBT+ communities are facing high risk for hepatitis B infection due to their activities. Thus, having a one-time hepatitis
B screening will improve awareness and management of chronic hepatitis B in our communities. Please talk to your healthcare provider and ask
them to order the following lab work for screening:
● Triple panel
○ HBsAg (HBV surface antigen)
○ anti-HBs (HBV surface antibody)
○ total anti-HBc (HBV core antibody, total)

3. Periodic Hepatitis B Testing for Susceptible Persons in High-Risk Populations for Hepatitis B Infection
If you are susceptible to AND living in one or some of the high-risk situations of hepatitis B infection, periodic hepatitis B testing with the same
lab work as hepatitis B screening is recommended. If these conditions
apply to you, essential things are testing hepatitis B and subsequently
completing the HepB series as soon as possible.
A new recommendation says to you, “Don’t hesitate to ask for a hepatitis B test
without disclosing any reason for the test in a clinic.”
