Because of the risk of hepatitis B in infants becoming chronic, the CDC recommends that all infants be vaccinated, starting with the first dose at birth.
How likely is it that acute Hepatitis B will become chronic?
The likelihood depends upon the age at which someone becomes infected. The younger a person is when infected with Hepatitis B virus, the greater his or her chance of developing chronic Hepatitis B. Approximately 90% of infected infants will develop chronic infection. The risk goes down as a child gets older. Approximately 25%–50% of children infected between the ages of 1 and 5 years will develop chronic hepatitis. The risk drops to 6%–10% when a person is infected over 5 years of age. Worldwide, most people with chronic Hepatitis B were infected at birth or during early childhood.
