GeoVax Labs Secures Ebola Vaccine Patent

GeoVax Labs, Inc. (Nasdaq: GOVX) has been granted a patent that covers its vector platform for expressing ebolavirus antigens in virus-like particles (VLPs) utilizing an MVA viral vector. The patent’s claims encompass multiple ebolavirus strains, including Sudan ebolavirus, Zaire ebolavirus, Taï Forest ebolavirus, and Reston ebolavirus. The company’s share price rose 14% premarket following the news.

David Dodd, GeoVax President and CEO, said, “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 previously demonstrated that a single intramuscular dose of its vaccine candidate, GEO-EM01, provided 100% protection in rhesus macaques challenged with a lethal dose of Zaire ebolavirus.

In July 2021, GeoVax 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.

GeoVax is committed to addressing highly fatal endemic threats throughout the world, and to supporting critically important biodefense initiatives. 

About Geovax

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.
