Revaccination with Fendrix® or HBVaxPro® results in better response rates than does revaccination with three doses of Engerix-B® in previous non-responders

► We examined four different revaccination regimens in hepatitis B vaccine non-responders. ► Hypo-responders were more likely to respond to revaccination than zero-responders. ► Revaccination with HBVaxPro-40® and Fendrix® performed better than with Engerix-B®.
