ATLANTA – A federal vaccine advisory panel is considering options for ensuring that health care personnel who were vaccinated against hepatitis B in the remote past are currently protected.
Increasing proportions of health care personnel were vaccinated against hepatitis B in infancy, or as a catch-up during adolescence. An estimated 90%-95% of healthy adults aged 40 years and younger achieve a protective antibody titer (defined as anti–hepatitis B surface antigen concentrations of 10 mIU/mL or greater) after receiving the three-dose series (MMWR 2011;60[RR07]:1-45).
