About Hepatitis B

Hepatitis B is one of the world’s most significant infectious disease threats with more than 290 million people infected globally. HBV infection is the leading cause of liver disease and, with current treatments, it is very difficult to cure, with many patients going on to develop liver cancers. An estimated 900,000 people die each year from complications of chronic HBV such as liver decompensation, cirrhosis, and hepatocellular carcinoma.

About VBI’s 3-Antigen Hepatitis B Vaccine

VBI’s vaccine candidate is a 3-antigen hepatitis B vaccine, comprised of the S, pre-S1, and pre-S2 surface antigens of the hepatitis B virus, and is approved for use and commercially available in Israel. In December 2017, VBI initiated patient dosing in a global Phase 3 clinical program that consisted of two concurrent pivotal studies: PROTECT, a safety and immunogenicity study, and CONSTANT, a lot-to-lot consistency study. Data from both the PROTECT study and the CONSTANT study, which were announced in June 2019 and January 2020, respectively, comprise the basis for the regulatory submissions in the U.S. and Europe, which were submitted in November 2020, and for Canada and the U.K., which are in process. This vaccine is sold under the name Sci-B-Vac^® in Israel.
