GeoVax's Multi-Antigen COVID-19 Vaccine Shows Promise for Immunocompromised Patients
TL;DR
GeoVax's GEO-CM04S1 vaccine offers superior immune protection for immunocompromised patients, potentially capturing a significant market share in underserved vaccine populations.
GEO-CM04S1 is a multi-antigen MVA-based COVID-19 vaccine that induces cross-variant antibody and robust cellular immune responses through Phase 2 clinical trials.
This vaccine provides critical protection for vulnerable immunocompromised patients, improving health equity and reducing severe COVID-19 outcomes in high-risk populations.
GeoVax's novel vaccine demonstrates enhanced immune responses in leukemia patients compared to mRNA vaccines, with data presented at international scientific conferences.

GeoVax Labs, Inc. announced that clinical data for its next-generation COVID-19 vaccine, GEO-CM04S1, will be presented at two international scientific conferences in September 2025. The data highlights cross-variant antibody and robust cellular immune responses in immunocompromised patients with hematologic malignancies, a population for whom current authorized COVID-19 vaccines have shown insufficient protection.
Chief Medical Officer Kelly T. McKee, Jr., MD, MPH will present at the 6th ESCMID Conference on Vaccines in Lisbon, Portugal on September 12, 2025. The presentation, titled "GEO-CM04S1, a multi-antigen COVID-19 vaccine for immunocompromised individuals: clinical evaluation to date," will showcase the vaccine's performance in vulnerable patient populations.

Additional data will be presented at the International Workshop on Chronic Lymphocytic Leukemia (iwCLL 2025) in Krakow, Poland on September 15, 2025. Alexey V. Danilov, MD, PhD from City of Hope National Medical Center will present Phase II randomized study results showing that the MVA-based GEO-CM04S1 vaccine produces improved cellular immune response in patients with chronic lymphocytic leukemia compared to mRNA-based vaccines. Conference details are available at https://www.iwcll.org/events/xxi-iwcll-12-15-september-2025-krakow-poland/.
The GEO-CM04S1 vaccine is currently in three Phase 2 clinical trials, evaluating its effectiveness as a primary vaccine for immunocompromised patients, a booster vaccine for CLL patients, and a more robust, durable booster for healthy patients who previously received mRNA vaccines. This development addresses a critical healthcare need, as immunocompromised individuals, particularly those with hematologic cancers, have remained at elevated risk despite widespread vaccination efforts.
The promising clinical data suggests that multi-antigen vaccine approaches may provide broader and more durable protection against COVID-19 variants, potentially changing how vulnerable populations are protected against respiratory viruses. This advancement could significantly impact public health strategies for immunocompromised patients worldwide.
