GEO-MVA Advancing as the Leading U.S.-Developed Mpox Vaccine Candidate

ATLANTA, GA - April 24, 2025 (NEWMEDIAWIRE) - GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing vaccines and immunotherapies for infectious diseases and cancer, today responded to the recent detection of Clade I Mpox viral particles in wastewater samples in Greenville, North Carolina - the first such identification in the state. This finding, disclosed by the North Carolina Department of Health and Human Services (NCDHHS), underscores the increasing threat posed by Clade I Mpox and the urgent need for expanded preparedness and Mpox vaccine availability.

This development aligns with concerns raised by the Centers for Disease Control and Prevention (CDC), which continues to monitor Clade I Mpox - a more virulent strain associated with higher transmissibility and a greater case fatality rate than Clade II. Four confirmed Clade I Mpox cases have been reported in the U.S. to date - in California, Georgia, New Hampshire, and New York​.

“The detection of Clade I Mpox in North Carolina wastewater is a warning shot - silent transmission may be occurring even before clinical cases are reported,” said David Dodd, Chairman and CEO of GeoVax. “We encourage public health authorities to act decisively to expand our Mpox vaccine supply and ensure rapid, scalable access to effective solutions.”

GEO-MVA: A U.S.-Developed Vaccine Candidate at the Forefront of Biosecurity

During this week’s World Vaccine Congress in Washington, D.C., GeoVax’s GEO-MVA vaccine was the focus of several high-level discussions as the leading U.S.-developed vaccine candidate for Mpox/smallpox. GEO-MVA is advancing in development as a strategic complement to the existing global Mpox vaccine supply option, which is currently reliant on a single overseas-manufactured vaccine from a European supplier.

GeoVax has completed cGMP manufacturing of GEO-MVA and anticipates the availability of clinical vialed product soon. Clinical trials are expected to commence in the second half of 2025​​.

GEO-MVA directly aligns with the strategic recommendations issued by the CDC, WHO, and biodefense think tanks urging governments to reduce dependence on single suppliers and bolster domestic manufacturing capacity​​​. “Our discussions at the World Vaccine Congress reaffirmed the critical need and role that GEO-MVA can fulfill as the first U.S.-supplied Mpox vaccine,” said Dodd. “This is a pivotal opportunity to onshore our vaccine capabilities and protect Americans against future outbreaks.”

Strengthening Pandemic Preparedness Through Early Detection and Vaccine Access

The wastewater detection in North Carolina was facilitated by the state’s Wastewater Monitoring Network - a vital tool for identifying viral threats early. However, proposed federal funding cuts threaten the continuity of this critical infrastructure​.

GeoVax urges state and federal policymakers to take decisive action by:

• Expanding funding for surveillance systems that serve as early warning networks for viral emergence.
• Supporting U.S.-based manufacturing and vaccine diversification to enhance biosecurity and preparedness.
