Hepatitis A and

Hepatitis B Vaccine

Hepatitis A vaccine is used to prevent liver diseases caused by the Hepatitis A virus (HAV). HAV is usually spread by fecal-oral transmission or by consuming food or water that has been contaminated.

Hepatitis B vaccine is used to prevent liver diseases caused by the Hepatitis B virus (HBV). HBV is most commonly transmitted through direct blood-to-blood contact with an infected person.

The difference between Hepatitis A and B is that Hepatitis A causes acute illness. Hepatitis B begins as a short-term illness but if progressed can turn into a chronic illness or life-long infection. Chronic hepatitis B is the world’s leading cause of liver cancer and can lead to serious liver diseases such as cirrhosis or liver cancer.
