INTRODUCTION
Hepatitis B virus (HBV) vaccination has substantially reduced HBV-related morbidity and mortality.1 Infants infected with HBV in the first year of life have a 90% risk of developing chronic infection, which is associated with chronic liver disease and liver cancer.1 World Health Organization (WHO) data show that birth-dose HBV vaccination rates in the US increased from approximately 21% in 2002 to 66% to 75% in 2019,2 trends mirrored in Centers for Disease Control and Prevention (CDC) National Immunization Survey data.3 However, recent HBV vaccination rates remain unknown, representing a critical gap given increasing concerns about vaccine hesitancy.4
