Which type of hepatitis has no available vaccination?

Hepatitis C is the correct answer because, unlike Hepatitis A and Hepatitis B, there is currently no vaccine available for Hepatitis C. Hepatitis A has an effective vaccine that provides immunity, and Hepatitis B also has a vaccine that is widely used in many countries to prevent infection.

Hepatitis D is dependent on Hepatitis B for its existence and is often addressed through the immunization for Hepatitis B, as vaccination against Hepatitis B can prevent infection with Hepatitis D. On the other hand, Hepatitis C is primarily treated rather than prevented with vaccination, highlighting the lack of a vaccine in this case. Current treatment options can cure Hepatitis C, but the absence of a vaccine makes it unique among these types of viral hepatitis.
