What did the original study show?

This 2014 article reported promising immune responses from an experimental hepatitis C vaccine candidate. An early trial showing an immune response is not evidence that a vaccine prevents infection or is available for public use.

Is a hepatitis C vaccine available now?

As of October 2026, there is no approved effective vaccine against hepatitis C. This differs from hepatitis A and B, for which vaccines are available.

Major treatment development since 2014

The most important advance has been the widespread availability of highly effective direct-acting antiviral medicines. Current NHS treatment usually involves tablets for 8 to 12 weeks and cures hepatitis C in the great majority of people. Testing is essential because infection can be present without symptoms.
