GeoVax Announces Issuance of Ebola Vaccine Patent

Addressing Multiple Strains of Ebolavirus

Atlanta, GA, July 24, 2023 – GeoVax Labs, Inc. (Nasdaq: GOVX), a biotechnology company developing immunotherapies and vaccines against cancers and infectious diseases, today announced that the U.S. Patent and Trademark Office has issued Patent No. 11,701,418 B2 to GeoVax, pursuant to the Company’s patent application No. 15/543,139 titled “ Replication-Deficient Modified Vaccinia Ankara (MVA) and Matrix Protein (VP40).”

The claims granted by the patent generally cover GeoVax’s vector platform for expressing ebolavirus antigens in virus-like particles (VLPs) utilizing an MVA viral vector. The claims encompass multiple ebolavirus strains, including Sudan ebolavirus, Zaire ebolavirus, Taï Forest ebolavirus, and Reston ebolavirus.

GeoVax previously demonstrated that a single intramuscular (IM) dose of its vaccine candidate, GEO-EM01, provided 100% protection in rhesus macaques challenged with a lethal dose of Zaire ebolavirus (EBOV). GEO-EM01 is based on the Company’s novel MVA-VLP platform, which generates noninfectious VLPs in the individual being vaccinated. VLPs mimic a natural infection, triggering the body to produce a robust and durable immune response with both antibodies and T cells.

Additionally, in July 2021, the Company announced results of preclinical efficacy studies of its Sudan ebolavirus (SUDV) vaccine candidate, in which a single dose of the vaccine protected 100% of small animals challenged with a lethal dose of SUDV. Dr. Jason Comer of Sealy Institute for Vaccine Sciences, University of Texas Medical Branch (UTMB), recently discussed GeoVax’s Sudan virus vaccine efficacy. His presentation to the Global Health Preparedness Strategy and Priority Pathogens session at the 23 rd Annual World Vaccine Congress demonstrated partial protection following lethal Sudan virus challenge in a rigorous cynomolgus macaque model. This research project has been funded in whole or in part with Federal funds under a Preclinical Services Contract from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health.

David Dodd, GeoVax President and CEO, commented, “While our focus and development priorities continue to be our COVID-19 vaccine and cancer immunotherapy programs, developing vaccines against lethal hemorrhagic fever viruses, represents our commitment to addressing highly fatal endemic threats throughout the world, as well as our support of critically important biodefense initiatives. This patent allowance adds to our growing portfolio of wholly owned, co-owned, and in-licensed intellectual property, now standing at over 115 granted or pending patent applications spread over 24 patent families.”

GeoVax Labs, Inc. is a clinical-stage biotechnology company developing novel therapies and vaccines for solid tumor cancers and many of the world’s most threatening infectious diseases. The company’s lead program in oncology is a novel oncolytic solid tumor gene-directed therapy, Gedeptin ® , presently in a multicenter Phase 1/2 clinical trial for advanced head and neck cancers. GeoVax’s lead infectious disease candidate is GEO-CM04S1, a next-generation COVID-19 vaccine targeting high-risk immunocompromised patient populations. Currently in three Phase 2 clinical trials, GEO-CM04S1 is being evaluated as a primary vaccine for immunocompromised patients such as those suffering from hematologic cancers and other patient populations for whom the current authorized COVID-19 vaccines are insufficient, and as a booster vaccine in patients with chronic lymphocytic leukemia (CLL). In addition, GEO-CM04S1 is in a Phase 2 clinical trial evaluating the vaccine as a more robust, durable COVID-19 booster among healthy patients who previously received the mRNA vaccines. GeoVax has a leadership team who have driven significant value creation across multiple life science companies over the past several decades. For more information, visit our website: www.geovax.com.

Dear Georgia Life Sciences Community, As we reflect on the past year, I want to extend my sincere thanks to our Georgia Life Sciences members for making it such an impactful one. Your engagement and leadership continue to move our industry forward and advance our shared strategic priorities— driving strong policy, expanding the talent pipeline, and creating intentional spaces for collaboration across Georgia’s life sciences ecosystem. Our Year in Review captures the progress we’ve made together across these priorities and highlights the collective impact our members are having statewide—from strengthening the workforce and supporting manufacturing growth to elevating Georgia’s position as a national life sciences leader. This progress is only possible because of the collaboration, commitment, and insight of our member community. 

Investing in America’s Biopharmaceutical Infrastructure Strengthens the Economy and Supports Union Workers

By Maria Thacker Goethe • December 20, 2025
The biopharmaceutical industry is growing America’s manufacturing and R&D capabilities to develop the next generation of treatments. A recent study from PILMA quantified the impact of the industry’s investment in American infrastructure on the economy and union workforce across 18 states from 2019-2024. The study found that across the 18 states included, the biopharmaceutical industry: Supported the American economy by investing $86.5B in R&D and manufacturing infrastructure and developing 1000+ construction projects at over 700 distinct facilities. Strengthened the American workforce by generating $2.6B in skilled union wages and providing $19M in support for union apprenticeships. The impact of the biopharmaceutical industry’s investment in American manufacturing and union jobs extends beyond direct benefits, spurring additional economic activity in the communities where workers live. This is known as the multiplier effect . On average, every $1 of new investment in a U.S. biopharmaceutical manufacturing facilities generates an additional $1.59 in further economic activity (2.59x times the initial investment value). The industry’s $86.5B investment in R&D and manufacturing infrastructure has a total economic impact of $224B. Check out this resource to learn more about how biopharmaceutical investment in American infrastructure supports America’s workers and communities.

Georgia Life Sciences Joins National Coalition Urging Congressional Action on Key Innovation Policies

December 10, 2025
Georgia Life Sciences has joined 43 state and regional life sciences organizations in signing a national Council of State Bioscience Associations (CSBA) letter calling on Congress to take immediate action on three bipartisan policy priorities that are essential to sustaining U.S. leadership in biomedical innovation and supporting patients nationwide. With Congress back in session and several critical programs at risk of expiring, the letter urges congressional leaders to advance the following provisions without delay: 1. Reauthorize the Rare Pediatric Disease Priority Review Voucher (PPRV) Program The PPRV program has been instrumental in incentivizing the development of therapies for children with rare and life-threatening conditions. Its lapse threatens to slow or halt research that families across the country are counting on. 2. Extend the SBIR/STTR Programs The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs provide crucial early-stage capital for emerging biotech and medtech companies—many of them in Georgia. Without reauthorization, hundreds of innovative small businesses face uncertainty, jeopardizing new therapies, diagnostics, and technologies in the pipeline, 3. Advance PBM Transparency Reforms Greater transparency and accountability within pharmacy benefit manager (PBM) practices are needed to ensure that savings reach patients and employers. Reforming PBM operations is essential to strengthening access and affordability across the healthcare system. A Unified Message from the Life Sciences Community The sign-on letter reflects broad, bipartisan alignment across the national life sciences ecosystem: researchers, entrepreneurs, investors, patient advocates, and state associations all share a common message— these programs underpin America’s global competitiveness and are vital to patients who rely on continued scientific progress. Georgia Life Sciences has shared the letter with members of Georgia’s congressional delegation and will continue engaging with policymakers to emphasize the importance of swift action.
