VBI Vaccines Inc. (VBI) is initiating a voluntary nationwide recall of all remaining PreHevbrio^® [Hepatitis B Vaccine (Recombinant); NDC 75052-001-10] (“PreHevbrio”) due to the bankruptcy of the company and termination of operations.

Further distribution or use of any remaining PreHevbrio vaccine by healthcare providers or others must cease immediately.

VBI Vaccines Inc. and its affiliates commenced a proceeding under Canada’s Companies’ Creditors Arrangement Act, R.S.C. 1985, c. C-36, as amended (the “CCAA Proceeding”) on July 29, 2024, in the Superior Court of Justice (Commercial List) in Ontario, Canada. VBI Vaccines (Delaware) Inc. and certain other affiliates filed petitions and a motion under chapter 15 of the Bankruptcy Code for recognition of the Canadian Proceeding as a foreign main proceeding on July 30, 2024, in the United States Bankruptcy Court for the District of Delaware (together with the CCAA Proceeding, the “Restructuring Proceedings”). In connection with the Restructuring Proceedings, on October 25, 2024, the company issued an initial communication to healthcare providers and the FDA regarding its intent to voluntarily withdraw PreHevbrio from the U.S. market. The company is rapidly winding down all U.S. operations and has permanently ceased distribution of PreHevbrio, a vaccine indicated for the prevention of infection caused by hepatitis B virus in adults.

PreHevbrio vaccine was distributed nationwide to distributors and healthcare providers.
