Sanofi has completed its acquisition of Dynavax Technologies Corporation, bringing the adult hepatitis B vaccine HEPLISAV-B and several vaccine pipeline projects, including a shingles vaccine candidate currently in phase 1/2 studies, into its portfolio. Dynavax will now operate as an indirect, wholly owned subsidiary of Sanofi, and its common stock will no longer be traded on the NASDAQ. This move expands Sanofi’s presence in adult immunization by combining Dynavax’s differentiated vaccines with Sanofi’s commercial reach and development capabilities.
