Abstract
An estimated 100,000 to 150,000 new hepatitis B virus (HBV) infections occur each year in the United States1 and once infected, infants and children are much more likely to develop chronic HBV infections than are adults.1-3 However, early childhood infections can be prevented through hepatitis B vaccination of infants. The currently licensed hepatitis B vaccines have been shown to be safe, highly efficacious, and to provide long-term protection.1,4
