Hepatitis A and hepatitis B can both be prevented with vaccines. Cases of hepatitis A have dramatically declined in the United States over the past 20 years largely due to vaccination efforts. The hepatitis A vaccine is recommended for all children at one year of age and for adults who may be at increased risk.
Unfortunately, many people became infected with hepatitis B before the hepatitis B vaccine was widely available. The hepatitis B vaccine is now recommended for all infants at birth and for adults who may be at increased risk.
