GeoVax Labs, Inc. announced a significant milestone toward implementation of a validated chicken embryonic fibroblast (CEF) based production system for the company's MVA-based vaccines, with the release of its first lot of GEO-CM04S1 (next-generation Covid-19 vaccine) produced with a commercial manufacturing platform. This milestone marks the successful completion of the transfer and scale-up of manufacturing from the research-focused Center for Biomedicine & Genetics at City of Hope (Duarte, CA) to the experienced CDMO ABL Europe (a subsidiary of Oxford Biomedica), the Company's cGMP (current Good Manufacturing Procedures) manufacturing partner. GEO-CM04S1 is a next-generation Covid-19 vaccine based on GeoVax?s MVA viral vector platform, which supports the presentation of multiple vaccine antigens to the immune system in a single dose.

CM04S1 presents both the spike and nucleocapsid antigens of SARS-CoV-2 and is specifically designed to induce both antibody and T cell responses to non-variable parts of the virus. The more broadly specific and functional engagement of the immune system is designed to protect against the continually emerging variants of Covid-19. Results released during 2023 demonstrated the safety and efficacy of CM04S1 and emphasize the role it will play in protecting immunocompromised patients from greater risk of severe disease, hospitalization and death from SARS-CoV-2 infection.

In response to the global need to address the continued emerging threat from Mpox (monkeypox), GeoVax previously announced having secured rights from the National Institutes of Health (NIH) covering preclinical, clinical and commercial uses of the NIH-MVA as a vaccine against Mpox or smallpox. The Company is currently pursuing different regulatory pathways toward achievement of an expedited approval and intends to become the first U.S.-based supplier of the MVA vaccine to prevent Mpox and smallpox.
