About

A Controlled Trial to Assess the Lot-to-lot Consistency of Sci-B-Vac™ in Adults

Full description

The primary objective of the study is to verify that the manufacturing equivalence of Sci-B-Vac™ is consistent and to compare the immunogenicity and safety of a three-dose regimen of Sci-B-Vac™ to a three-dose regimen of Engerix-B® in adults.

Enrollment: 2,838 patients

Sex: All

Ages: 18 to 45 years old
