• Meet with GeoVax Labs’ Chairman & CEO David Dodd
• Learn Why Preparedness Against One Viral Threat Does Not Necessarily Ensure Preparedness Against the Next
• Discover the Potential Role of MVA-Based Vaccine Technologies in Addressing Emerging Infectious Disease Threats

ATLANTA, GA - May 27, 2026 (NEWMEDIAWIRE) - GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing vaccines and immunotherapies for infectious diseases and cancer, today announced that Chairman & Chief Executive Officer David Dodd will participate in Tribe Public’s CEO Presentation and Q&A Webinar Event titled, “Ebola, Marburg, Hantavirus, Mpox and Beyond: Building a Resilient Infectious Disease Preparedness Strategy.”

The webinar is scheduled to begin at 8:00 a.m. Pacific Time / 11:00 a.m. Eastern Time on Thursday, May 28, 2026.

“Ebola, Marburg, Mpox and most recently Hantavirus concerns all reinforce the same lesson: global preparedness strategies must evolve beyond reactive, single-threat approaches,” said David Dodd, Chairman and Chief Executive Officer of GeoVax. “GeoVax is focused on advancing versatile MVA-based vaccine technologies designed to support broader infectious disease preparedness and help address critical gaps in domestic and global biodefense infrastructure.”

The webinar discussion is expected to address:

• The growing importance of platform-based vaccine technologies in infectious disease preparedness
• Why emerging outbreaks continue to expose vulnerabilities in global response infrastructure
• The potential applicability of MVA-based technologies across multiple viral threats, including orthopox and hemorrhagic fever viruses
• The importance of scalable and resilient domestic vaccine manufacturing capabilities
