VBI Vaccines Announces Late-Breaker Poster Presentation at The Liver Meeting® 2019

VBI Vaccines Inc. (Nasdaq: VBIV) ("VBI"), a commercial-stage biopharmaceutical company developing next-generation infectious disease and immuno-oncology vaccines, today announced that the company's abstract titled, "Rapid Increase in Anti-HBsAg Titers and Higher Seroprotection Rates in Adults Immunized with Sci-B-Vac Compared to a Monovalent Hepatitis B Vaccine: Results from PROTECT ? a Double-Blind, Randomized, Controlled, Phase-3 Study," has been selected for a late-breaker poster presentation at the American Association for the Study of Liver Diseases (AASLD) ? The Liver Meeting®, on November 11, 2019.

Joanne Langley, M.D., Professor of Pediatrics and Community Health and Epidemiology, CIHR-GSK Chair in Pediatric Vaccinology, Dalhousie University, and Head of the Division of Infectious Disease, IWK Health Centre, and principal investigator of the PROTECT study, VBI's Phase 3 double-blind, randomized study that enrolled 1,607 subjects, will present the poster which highlights the immunogenicity and safety data from PROTECT, detailing three key immunologic takeaways:

1. The successfully-met co-primary endpoints of (i) non-inferiority of seroprotection rate in all subjects age 18+ who received Sci-B-Vac compared to Engerix-B, and (ii) superiority of seroprotection rate in subjects age 45+ who received Sci-B-Vac compared to Engerix-B;
2. Rapid increase in anti-hepatitis B surface antigen (HBsAg) titers, with higher seroprotection rates in subjects who received Sci-B-Vac compared to Engerix-B at all time points, suggesting a more rapid onset of protection; and
3. 5-8x higher antibody geometric mean concentration (GMC) in subjects who received Sci-B-Vac compared to Engerix-B, regardless of age, body mass index, diabetic status, and gender.
