Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of PresentationThe accompanying financial statements include the accounts of GeoVax Labs, Inc. and GeoVax, Inc. All intercompany transactions have been eliminated in consolidation. The financial statements are unaudited, but include all adjustments, consisting of normal recurring entries, which we believe to be necessary for a fair presentation of interim periods presented. Interim results are not necessarily indicative of results for a full year. The financial statements should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022. We expect our operating results to fluctuate for the foreseeable future; therefore, period-to-period comparisons should not be relied upon as predictive of the results in future periods.We believe that our existing cash resources will be sufficient to continue our planned operations into the fourth quarter of 2023. We are devoting substantially all of our present efforts to research and development of our vaccine and immunotherapy candidates and expect to require additional funding to continue our research and development activities. We plan to pursue additional cash resources through public or private equity or debt financings, government grants, arrangements with strategic partners, or from other sources. There can be no assurance that additional funding will be available on favorable terms or at all. These factors collectively raise substantial doubt about the Company’s ability to continue as a going concern within one year from the date these financial statements are issued. Management believes that we will be successful in securing the additional capital required to continue the Company’s planned operations, but that our plans do not fully alleviate the substantial doubt about the Company’s ability to operate as a going concern.The accompanying financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates realization of assets and the satisfaction of liabilities in the normal course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described above.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting PronouncementsDuring the three months ended March 31, 2023, there have been no new accounting pronouncements or changes in accounting pronouncements which we expect to have a material impact on our financial statements.
