TAIPEI, Taiwan and EMERYVILLE, Calif., Aug. 23, 2021 /PRNewswire/ -- Medigen Vaccine Biologics Corporation (MVC) (TPEx: 6547.TWO), a biopharmaceutical company focusing on the development and production of vaccines and biologics, and Dynavax Technologies Corporation (Nasdaq: DVAX), a biopharmaceutical company focused on developing and commercializing novel vaccines, today announced the rollout of its COVID-19 vaccine, MVC-COV1901. Approximately 600,000 people are anticipated to receive the Medigen vaccine this week.

Charles Chen, Chief Executive Officer at Medigen commented, "Medigen is honored to be able to serve the people of Taiwan and participate in the global response to this pandemic. We were grateful to have received emergency use authorization from the Taiwan FDA and greatly appreciate the time and effort of both the TFDA staff and the experts that participated in the risk and benefit analysis meeting. It is heartening to see a productive outcome from the dedicated effort from the team at Medigen."

Ryan Spencer, Chief Executive Officer of Dynavax commented, "We are pleased that Medigen's vaccine is now available for the people of Taiwan. We are very excited for this first, of hopefully multiple, EUAs and approvals for COVID-19 vaccines that include CpG 1018 adjuvant. Considering the limitations of current vaccines and the global vaccine shortage, we believe adjuvanted vaccines can contribute significantly to current vaccination efforts."

In July, MVC received Taiwan Emergency Use Authorization and approval for inclusion in Taiwan's COVID-19 vaccine immunization program, MVC-COV1901. MVC COVID-19 vaccine is indicated for adults over 20 years old and is administered in two doses 28 days apart for prevention of COVID-19. The Advisory Committee recommended that MVC should submit safety monitoring report monthly during the declared EUA period and should submit a vaccine effectiveness report within one year after obtaining EUA approval.

About MVC-COV1901
MVC-COV1901 is a subunit vaccine with recombinant S-2P antigen adjuvanted with CpG 1018 supplied by Dynavax and aluminum hydroxide. The S-2P antigen is a trimeric and prefusion-stable recombinant spike protein developed by the U.S. NIH. MVC has obtained a global technology license for S-2P from the U.S. Vaccine Research Center at National Institutes of Health (NIH). MVC-COV1901 vaccine's Phase 1 and 3,815-participant Phase 2 clinical study data has shown robust safety and promising immunogenicity responses and as a result obtained Taiwan's EUA approval on July 19th, 2021. MVC will continue to collaborate with international partners for phase 3 clinical trial development and assist the global community in its fight against the COVID-19 pandemic.
