The statement that HBV vaccine is recommended for unvaccinated adults at risk is accurate because hepatitis B virus (HBV) poses a significant health risk, particularly for individuals who are in high-risk categories. These categories include healthcare workers, individuals with multiple sexual partners, those with chronic liver disease, and individuals with high exposure to blood products or bodily fluids. Vaccination is an effective preventive measure against HBV infection, significantly reducing the risk of transmission and subsequent health complications such as chronic hepatitis, cirrhosis, or liver cancer.

Furthermore, the vaccination is important not only for children but for adults as well, especially those who have not yet been vaccinated and are at risk due to their lifestyles or occupations. Vaccination prior to exposure is crucial to help establish immunity and prevent infection. This is why the recommendation for unvaccinated adults at risk is particularly essential in the formulation of public health strategies aimed at controlling the spread of hepatitis B.
