Highlights Critical Need for Additional MVA Vaccine Supply, Ending the Current Monopoly, Increasing Access and Supply Worldwide

ATLANTA, GA, April 14, 2026 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing vaccines and immunotherapies against infectious diseases and cancer, today highlighted the urgent challenges caused by the supply-constrained, global orthopoxvirus vaccine market and outlined the strategic positioning of its GEO-MVA vaccine candidate to address the limited supply and increasing global demand.

A Procurement-Driven Market with Recurring Global Demand

The global market for vaccines targeting mpox and smallpox (orthopoxviruses) has evolved into a recurring, procurement-driven market supported by:

• National stockpile programs across the United States, Europe and allied countries
• Ongoing purchasing by global health organizations and regional agencies
• Outbreak-driven surge demand tied to periodic global transmission events

Recent mpox outbreaks across multiple continents, including the emergence of more virulent strains, have reinforced the need for sustained vaccine supply beyond emergency response cycles.

Single-Supplier Market Structure and Limited Surge Capacity

The current global supply of MVA vaccines, the preferred vaccine for orthopoxvirus infections due to their recognized safety for use in vulnerable populations, is concentrated with a single commercial supplier.

This market structure has contributed to:

• Limited surge capacity during outbreaks
• Repeated depletion of government stockpiles
• Increased focus on supply chain resilience and diversification

As a result, governments and public health agencies are increasingly prioritizing:

• Establishment of additional sources of MVA vaccine supply
• Expansion of domestic and allied manufacturing capacity
• Reduced dependence on single-source providers for critical countermeasures

An Established Market Measured in Hundreds of Millions Annually

Public disclosures and procurement activity indicate that the mpox/smallpox vaccine market:

• Has generated hundreds of millions of dollars in annual procurement in recent years
• Includes multiyear purchasing frameworks and forward-looking supply agreements
• Is supported by both baseline stockpiling demand and outbreak-driven purchasing cycles

GeoVax believes these dynamics support a durable and expanding global market, rather than a one-time, pandemic-driven market opportunity.

GEO-MVA Positioned as a Second-Source MVA Vaccine Candidate

GeoVax’s GEO-MVA vaccine candidate is being developed to address the current supply-demand imbalance. The Company believes GEO-MVA is positioned as a potential second-source MVA vaccine, with key attributes including:

• Leverages the established MVA platform, widely used for immunocompromised and high-risk populations
• A defined regulatory pathway, based on immuno-bridging, to an approved MVA vaccine
• Late-stage development readiness, with Phase 3 initiation planned during 2026

GeoVax believes GEO-MVA has the potential to support:

• National stockpile replenishment programs
• Global outbreak response efforts
• Long-term preparedness and biodefense strategies

Alignment with Public Health and Biodefense Priorities

The mpox/smallpox vaccine market is increasingly shaped by the intersection of:

• Public health preparedness, driven by recurring mpox outbreaks and evolving viral threats
• National security and biodefense priorities, including protection against biological threats

Recent U.S. and international policy initiatives have emphasized:

• Strengthening biosecurity infrastructure
• Expanding domestic manufacturing capabilities
• Ensuring reliable access to critical medical countermeasures

GeoVax believes GEO-MVA is positioned for both civilian and biodefense procurement channels.

Development Timeline Synchronized with Procurement Cycles

GeoVax believes its planned development timeline for GEO-MVA corresponds with:

• Anticipated stockpile replenishment cycles following recent depletion
• Continued global procurement activity driven by outbreak preparedness
• Increasing policy emphasis on supply diversification initiatives

David Dodd, Chairman and Chief Executive Officer of GeoVax, commented, “The mpox and smallpox vaccine market is not a future construct, it is an active, procurement-driven market with recurring demand and increasing strategic importance. It is also a market currently defined by supply concentration and limited surge capacity.”

Mr. Dodd added, “We believe that, if approved, GEO-MVA, which is expected to begin a pivotal Phase 3 trial this year, is positioned to enter this market as a second-source MVA vaccine at a time when governments and global health organizations are actively seeking to diversify supply and strengthen preparedness. Our focus is on executing the next phase of development and aligning GEO-MVA with procurement frameworks that support both long-term stockpiling and rapid response capabilities.”

MVA-X Platform Demonstrates Single-Dose Durable Protection Comparable to Two-Dose Regimen

ATLANTA, GA, April 2, 2026 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing vaccines and immunotherapies for infectious diseases and cancer, today highlighted preclinical data presented at the World Vaccine Congress Washington 2026 supporting the potential for a single-dose Modified Vaccinia Ankara (MVA)-based mpox vaccine. The data demonstrate that a novel MVA vaccine construct incorporating an immunomodulatory peptide (“MVA-X”) achieved protective efficacy, comparable to the traditional two-dose MVA regimen, in a murine orthopoxvirus challenge model.

• The presentation, titled “Next-Generation MVA Mpox Vaccines: Harnessing an Immunomodulatory Peptide for Single-Dose Efficacy,” was delivered by Heather Koehler, Ph.D., of Washington State University, during the Immune Profiling track on April 1, 2026.
• Single-dose efficacy: the MVA-X vaccine construct achieved complete protection comparable to a two-dose MVA vaccine regimen in a lethal orthopox challenge model, while a single-administration of MVA showed only partial protection.
• Durable protection: Protective immunity was maintained through Day 150 post-vaccination, with 100% survival observed in both MVA-X (single-dose) and two-dose MVA groups.
• Robust viral control: MVA-X demonstrated significant reduction in lung viral burden, comparable to the two-dose MVA regimen.
• Improved clinical outcomes: MVA-X vaccinated animals exhibited minimal weight loss, reduced disease severity, and preserved lung structure.
• T cell-driven immunity: Protection in MVA-X vaccinated animals was independent of neutralizing antibodies, supported by enhanced CD4+ and CD8+ T cell responses.

Mechanistic Innovation

The MVA-X construct incorporates a peptide designed to transiently modulate the PD-1 immune checkpoint pathway, enhancing T cell activation and durability of immune response during vaccination.

This approach enables:

• Stronger and more sustained T cell responses
• Enhanced immune memory
• Potential for durable protection with fewer doses

This represents a novel application of immune checkpoint modulation within vaccine design.

“These findings provide an important proof-of-concept that the performance of MVA-based vaccines can be enhanced to potentially achieve single-dose protection,” said Mark Newman, Ph.D., Chief Scientific Officer of GeoVax. “The preclinical data demonstrates a clear biological signal that supports continued exploration of immune-enhanced MVA constructs.”

David A. Dodd, Chairman and Chief Executive Officer of GeoVax, added: “As mpox continues to emerge as a recurring global health and biodefense concern, the need for vaccines that are both durable and rapidly deployable has become increasingly clear. An MVA-X vaccine may offer the opportunity to meaningfully improve vaccination coverage, compliance, and outbreak response – particularly in resource-constrained or high-risk environments.”

Dodd further noted: “These results reinforce the strength and flexibility of the MVA platform that underpins our GEO-MVA program. With a defined regulatory pathway in place and preparations underway to initiate a Phase 3 immune bridging study, GeoVax is focused on advancing an MVA vaccine designed to expand global supply, support public health preparedness, and address the limitations of existing options.”

Strategic Context

• Supports Single-Dose Strategy for MVA-based immunization: Potential to simplify vaccination and improve real-world deployment
• Aligns with Market Need: Potential to addresses drawbacks of current mpox vaccines, including multi-dose requirements and durability

About the Study

The study evaluated MVA-X, an MVA-based vaccine incorporating an immunomodulatory peptide sequence designed to enhance T cell responses. In murine models, animals were challenged with high-dose vaccinia virus at multiple timepoints (Days 55, 90, and 150), with outcomes including survival, viral load, clinical pathology, and immune response.

Peer-Reviewed Article Describes Clinical and Immunologic Rationale for Dual-Antigen MVA-Based Vaccine Designed to Address Limitations of First-Generation COVID-19 Vaccines in Highly Vulnerable Populations

ATLANTA, GA – March 12, 2026 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing vaccines and immunotherapies for infectious diseases and solid tumors, today announced the publication of a peer-reviewed article describing its next-generation COVID-19 vaccine candidate, GEO-CM04S1, in Medical Research Archives, the journal of the European Society of Medicine.

The article, titled “GEO-CM04S1: A Dual-Antigen COVID-19 Vaccine for Immunocompromised Patients,” provides a comprehensive review of the vaccine’s scientific rationale, preclinical studies, and clinical findings supporting its development as a vaccine designed specifically to protect immunocompromised individuals who often respond poorly to currently authorized COVID-19 vaccines.

The publication highlights how GEO-CM04S1’s dual-antigen design (Spike + Nucleocapsid) delivered via a Modified Vaccinia Ankara (MVA) viral vector is intended to generate antibody and T-cell responses that are both broad and durable, addressing limitations in such vulnerable populations of single-antigen vaccines that primarily target the spike protein.

The publication discusses how next-generation vaccines designed to stimulate more robust and durable cellular immunity may offer improved protection for these high-risk populations.

Scientific Highlights from the Publication

Key findings summarized in the publication include:

1. Dual-Antigen Design to Enhance Immune Breadth: GEO-CM04S1 expresses both the spike (S) and nucleocapsid (N) proteins of SARS-CoV-2, allowing the vaccine to stimulate immune responses against conserved viral targets that are less susceptible to mutation and immune escape.

2. Robust T-Cell Responses: Preclinical and clinical data show the vaccine induces strong CD4+ and CD8+ T-cell responses, which are critical for controlling viral infection and reducing progression to severe disease.

3. Favorable Safety and Immunogenicity: Early clinical studies demonstrated a benign safety profile and strong immunologic responses, including seroconversion and cellular immune activation across multiple dose levels.

4. Encouraging Results in Immunocompromised Patients: Early readouts from ongoing Phase 2 clinical trials in patients with hematologic malignancies receiving cell transplants, and individuals with chronic lymphocytic leukemia, indicate the vaccine can generate durable immune responses even in patients with impaired immune systems.

David Dodd, Chairman and Chief Executive Officer of GeoVax, stated: “This publication reinforces the scientific rationale for GEO-CM04S1 as a purpose-built vaccine for immunocompromised populations that remain inadequately protected by current COVID-19 vaccines. An estimated 40+ million patients in the U.S. are considered immunocompromised, including patients with cancer, transplant recipients, individuals receiving immunosuppressive therapies, and those with chronic diseases. These individuals may fail to mount adequate immune responses following vaccination and remain at higher risk of severe COVID-19 outcomes.  Worldwide, an estimated 400 million patients have such weakened immune systems, rendering them at risk of severe infection, hospitalization and potential death.”

Mark J. Newman, PhD, Chief Scientific Officer of GeoVax and co-author of the publication, added: “A growing body of evidence demonstrates that strong and early T-cell responses play a critical role in controlling SARS-CoV-2 infection and preventing severe disease. GEO-CM04S1 was designed specifically to stimulate these responses, which may be particularly important for immunocompromised individuals who often fail to generate adequate antibody responses to existing vaccines.  The MVA vector platform provides an ideal backbone for next-generation vaccines due to its ability to safely induce durable humoral and cellular immunity. Our dual-antigen strategy also expands immune recognition beyond the spike protein, and data from small animal studies indicates efficacy against variants is induced, reducing the need to continually update vaccines.”

About GEO-CM04S1

GEO-CM04S1 is a dual-antigen Modified Vaccinia Ankara (MVA)-vectored COVID-19 vaccine designed to induce durable T-cell and antibody responses against SARS-CoV-2.

The vaccine is currently being evaluated in multiple Phase 2 clinical trials, including:

• Primary vaccination in immunocompromised individuals
• Booster vaccination in patients with chronic lymphocytic leukemia (CLL)

The vaccine’s multi-antigen design and viral vector platform are intended to provide broader, more durable immune protection and improved efficacy in populations where first-generation vaccines have demonstrated reduced effectiveness.

Program Reaches Strategic Inflection Point as GEO-MVA Advances Toward Pivotal Phase 3 Study

Atlanta, GA – March 11, 2026 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing vaccines and immunotherapies against infectious diseases and cancer, today announced that it has begun engaging with global health and preparedness organizations to explore potential future procurement of its GEO-MVA vaccine candidate for mpox and smallpox preparedness programs.

GeoVax has initiated discussions and is soliciting interest from international organizations that influence or directly procure mpox/smallpox vaccines. These organizations play key roles in recommending or directly procuring vaccines for national preparedness stockpiles and international outbreak response programs.

The outreach reflects growing global recognition of the need to diversify supply of Modified Vaccinia Ankara (MVA) vaccines used for protection against mpox and smallpox. Currently, global supply of MVA vaccines is concentrated in a single commercial manufacturer.

Global preparedness programs for smallpox and mpox vaccines represent a potential multi-billion-dollar procurement market supported by national stockpiles, military preparedness programs, and international health organizations. Governments have invested billions of dollars in medical countermeasure stockpiles over the past two decades, and demand for MVA-based vaccines is expected to further expand as mpox continues to emerge as a recurring global health threat.

GeoVax believes that initiating engagement with procurement and preparedness organizations represents an important transition from development toward commercialization planning, reflecting growing confidence in the GEO-MVA program and the potential for the vaccine to contribute to global preparedness stockpiles following successful completion of the planned Phase 3 study, scheduled to initiate in the second half of 2026.

Advancing GEO-MVA Through an Expedited Regulatory Pathway

GeoVax’s GEO-MVA program has progressed through an extensive regulatory dialogue with the European Medicines Agency (EMA), culminating in scientific advice in support of an expedited development pathway based on a single immunobridging trial to the licensed MVA vaccine.

“The EMA carefully evaluated the scientific evidence over an extended period before confirming an expedited pathway. We believe their guidance validates both the scientific foundation of GEO-MVA and the growing recognition that expanding the global MVA vaccine supply is an important public health priority,” said David Dodd, Chairman and Chief Executive Officer of GeoVax.

“We have also been encouraged by the positive response we are receiving from global health organizations and preparedness agencies as we initiated these discussions,” Dodd continued. “We view this engagement as an endorsement of the progress we have made, our commitment to advancing GEO-MVA, and the potential of GEO-MVA to help address the current worldwide need for expanded MVA vaccine supply. Importantly, it also represents a critical step toward commercialization of GEO-MVA and the potential generation of meaningful revenues through government and global health procurement programs as the program advances through its final development stages.”

Implications for Global Preparedness and Biodefense Readiness

The discussions initiated by GeoVax occur amid growing policy dialogue regarding the strategic importance of expanding global MVA vaccine manufacturing capacity. GeoVax believes GEO-MVA has the potential to become a strategically important medical countermeasure supporting both global public health preparedness and national biodefense initiatives.

Recent mpox outbreaks have reinforced the understanding that mpox is not a single episodic event, but rather an evolving infectious disease threat with potential for continued geographic expansion and recurrence. As a result, governments and international health organizations are increasingly emphasizing the need for manufacturing diversification and supply redundancy for vaccines used in outbreak response and biodefense preparedness.

In the United States, policymakers and defense stakeholders have increasingly recognized that no domestic manufacturing capability currently exists for MVA vaccines, a gap with implications for both civilian preparedness and military readiness.

“Establishing additional MVA manufacturing capability is increasingly viewed as an important component of global preparedness,” said Dodd. “We are seeing growing interest from public health organizations, governments, and defense stakeholders who recognize the strategic importance of supply diversification.”

About GEO-MVA

GEO-MVA is GeoVax’s candidate vaccine for protection against mpox and smallpox based on the Modified Vaccinia Ankara (MVA) platform. Pending successful completion of the planned immunobridging trial, GEO-MVA could represent an important additional source of MVA vaccine supply for global preparedness, outbreak response, and biodefense programs.

Company Highlights GEO-MVA Manufacturing Readiness and Clear Clinical Pathway to Support Global Supply Diversification

ATLANTA, GA – February 17, 2026 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing vaccines and immunotherapies for infectious diseases and cancer, today issued a statement endorsing the urgent call to action articulated by Rosamund Lewis, MD (WHO Head, Poxviruses Programme) and colleagues in their recently published PLOS Medicine article, “The mpox epidemic is not over: Reducing disproportionate burden in Africa and persistent global risk require a sustained response.” (https://journals.plos.org/plosmedicine/article/file?id=10.1371/journal.pmed.1004893&type=printable)

The article underscores that, despite declining attention in some regions, mpox transmission, morbidity, and mortality continue, particularly across Africa, driven by evolving viral clades, constrained vaccine supply, and persistent inequities in access to countermeasures. Dr. Lewis reinforced these concerns in a recent public call to action, emphasizing that sustained political will, financing, and expanded vaccine availability remain essential to controlling mpox as a global health threat.

“GeoVax strongly endorses Dr. Lewis’s message that the mpox epidemic is not over and that complacency would be a costly mistake,” said David Dodd, Chairman and Chief Executive Officer of GeoVax. “The data are clear: mpox continues to circulate, evolve, and disproportionately impact vulnerable populations. A durable response requires sustained investment, diversified vaccine supply, and readiness that extends beyond reactive surge manufacturing.”

GEO-MVA: Advancing Toward an Expanded Global MVA Vaccine Supply

GeoVax’s GEO-MVA, a Modified Vaccinia Ankara (MVA)-based vaccine for the prevention of mpox and smallpox, is being developed specifically to help address the structural vulnerabilities highlighted in the PLOS Medicine analysis – most notably the world’s continued dependence on a single manufacturer for licensed MVA vaccine supply.

Key GEO-MVA program milestones include:

• Completion of GEO-MVA clinical material, positioning the program for late-stage clinical execution and supply readiness
• Planned initiation of a pivotal Phase 3 immunobridging study in Q4 2026, aligned with formal Scientific Advice from the European Medicines Agency supporting an expedited registration pathway
• Anticipated availability of immunobridging results in Q2 2027, supporting potential regulatory submissions and procurement discussions

“With a clearly defined regulatory pathway ahead, GEO-MVA is transitioning from preparedness planning to execution,” Dodd added. “This program is designed not only to meet regulatory requirements, but to support long-term global readiness by expanding MVA vaccine capacity in a market that remains chronically supply-constrained.”

Sustained Preparedness Requires Sustained Supply

The PLOS Medicine authors emphasize that mpox will continue to pose a global risk due to ongoing zoonotic spillover, viral evolution, and efficient transmission networks, particularly in settings where health systems are under-resourced. GeoVax believes these realities reinforce the need for redundant, geographically diversified MVA manufacturing capacity – a principle that underpins the GEO-MVA program.

“As the mpox response evolves from emergency reaction to long-term control, vaccine supply resilience becomes a cornerstone of preparedness,” said Dodd. “GeoVax is committed to supporting that objective by advancing GEO-MVA as an additional MVA vaccine option for public-health and biodefense stakeholders worldwide.”

About GeoVax

GeoVax Labs, Inc. is a clinical-stage biotechnology company developing novel vaccines against infectious diseases and therapies for solid tumor cancers. The Company’s lead clinical program is GEO-CM04S1, a next-generation COVID-19 vaccine currently in three Phase 2 clinical trials, being evaluated as (1) 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, (2) a booster vaccine in patients with chronic lymphocytic leukemia (CLL) and (3) a more robust, durable COVID-19 booster among healthy patients who previously received the mRNA vaccines. In oncology the lead clinical program is evaluating a novel oncolytic solid tumor gene-directed therapy, Gedeptin^®, having recently completed a multicenter Phase 1/2 clinical trial for advanced head and neck cancers.
