VACCINE INFORMATION
Hepatitis A, Hepatitis B, and Combined A+B Vaccines
Protecting liver health through immunization
Viral hepatitis is an infectious disease that affects liver function. Without proper prevention or treatment, it may lead to serious complications such as cirrhosis or liver cancer.
Vaccines are available to protect against major types of viral hepatitis, including Hepatitis A, Hepatitis B, and the combined A+B vaccine, which helps build immunity against both diseases at the same time.
