Vaccines are available for both Hepatitis A and Hepatitis B. While they both cause liver inflammation, Hepatitis B is a more serious infection and causes 10 times more deaths than Hepatitis A in the United States every year. Unlike Hepatitis B, Hepatitis A doesn’t usually cause long-term, chronic health problems. Hepatitis B can cause liver cancer and cirrhosis, a chronic form of liver damage. Because the liver is so important to breaking down toxins and creating compounds that prevent bleeding, maintaining good liver function is vital to a person’s health.
