Read the story of the hepatitis E vaccine.
Hepatitis A is a contagious, acute inflammatory disease of the liver. The Centers for Disease Control and Prevention estimates that nearly 25,000 people contracted hepatitis A in the United States in 2007, although the number of reported cases is much lower because some people do not show symptoms. Most people who contract hepatitis A will recover completely, but an estimated 100 people die from the infection every year in the United States.
