Basis of Accounting [Text Block]	2. Basis of Presentation The accompanying condensed consolidated financial statements at June 30, 2015 and for the three and six month periods ended June 30, 2015 and 2014 are unaudited, but include all adjustments, consisting of normal recurring entries, which we believe to be necessary for a fair presentation of the dates and 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 financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014. 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. Our financial statements have been prepared assuming that we will continue as a going concern, which contemplates realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the date of the financial statements. We are devoting substantially all of our present efforts to research and development of our vaccine candidates. We have funded our activities to date from government grants and clinical trial assistance, and from sales of our equity securities. We will continue to require substantial funds to continue our research and development activities. We believe that our existing cash resources and grant commitments will be sufficient to fund our planned operations through the first quarter of 2016, but due to our history of operating losses and our continuing need for capital to conduct our research and development activities, there is substantial doubt concerning our ability to operate as a going concern beyond that date. We are currently exploring sources of capital through government grants and clinical trial support and through philanthropic foundation support. We may also secure additional funds through sales of our equity securities or the exercise of currently outstanding stock purchase warrants. Management believes that the Company’s demonstrated history of successful funding through both government sources and equity securities alleviate the substantial doubt about the Company’s ability to operate as a going concern. However, additional funding may not be available on favorable terms or at all. If we fail to obtain additional capital when needed, we may be required to delay, scale back, or eliminate some or all of our research and development programs as well as reduce our general and administrative expenses.

Significant Accounting Policies and Recent Accounting Pronouncements We disclosed in Note 2 to our financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014 those accounting policies that we consider significant in determining our results of operations and financial position. There have been no material changes to, or in the application of, the accounting policies previously identified and described in the Form 10-K. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers There have been no other recent accounting pronouncements or changes in accounting pronouncements during the six months ended June 30, 2015 which we expect to have a material impact on our financial statements.

Notes to Financial Statements
Earnings Per Share [Text Block]	4. Basic and Diluted Loss Per Common Share Basic net loss per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net loss per share is computed using the weighted-average number of common shares and potentially dilutive common share equivalents outstanding during the period. Potentially dilutive common share equivalents consist of convertible preferred stock, stock options and stock purchase warrants. Common share equivalents which potentially could dilute basic earnings per share in the future, and which were excluded from the computation of diluted loss per share, as the effect would be anti-dilutive, totaled approximately 79.0 million and 12.8 million shares at June 30, 2015 and 2014, respectively.

Preferred Stock [Text Block]	7. Preferred Stock Series B Convertible Preferred Stock As of June 30, 2015, there are 100 shares of our Series B Convertible Preferred Stock outstanding (issued in December 2013), convertible into 285,714 shares of our common stock. During the six months ended June 30, 2015, there were no conversions or other transactions involving our Series B Convertible Preferred Stock. Series C Convertible Preferred Stock In February 2015, we established from the authorized preferred stock a series of preferred stock, consisting of 3,000 shares of Series C Convertible Preferred Stock, $1,000 stated value (“Series C Preferred Shares”) and entered into a Securities Purchase Agreement (“SPA”) whereby we issued to two institutional investors (“Purchasers”) the Series C Preferred Shares for gross proceeds of $3.0 million. Net proceeds to the Company from this transaction, after deduction of placement agent fees and other expenses, were approximately $2.7 million. The Series C Preferred Shares may be converted at any time at the option of the Purchasers into shares of our common stock. The initial conversion price of the Series C Preferred Shares was $0.18 per share (“Conversion Price”). The Series C Preferred Shares have a liquidation preference equal to the initial purchase price, have no voting rights, and are not entitled to a dividend. The Series C Preferred Shares contains price adjustment provisions, which may, under certain circumstances, reduce the Conversion Price on several future dates according to a formula based on the then-current market price for our common stock. As discussed below, on April 8, 2015 the Conversion Price was adjusted to $0.142 per share resulting in an aggregate total of 21,126,760 shares of our common stock (“Conversion Shares”) into which the Series C Preferred Shares currently may be converted. Pursuant to the terms of the SPA, we issued to each Purchaser Series D, E and F Warrants (collectively, the “Investor Warrants”), each to purchase up to a number of shares of our common stock equal to 100% of the Conversion Shares underlying the Series C Preferred Shares (up to 16,666,666 shares in the aggregate for each of the three series of warrants, or 49,999,998 shares in total). The Series D Warrants had an initial exercise price of $0.22 per share, are currently exercisable, and have a term of exercise equal to five years from the date of issuance. The Series E Warrants had an initial exercise price of $0.18 per share, are currently exercisable, and have a term of exercise equal to one year from the date of issuance. The Series F Warrants had an initial exercise price of $0.22 per share and have a term of exercise equal to five years from the date of issuance, but only vest and become exercisable upon, and in proportion to, the exercise of the one-year Series E Warrants. We also issued to our placement agent warrants (“Placement Agent Warrants”) to acquire 1,333,333 shares of our Common Stock with terms substantially the same as the Series D Warrants. The Investor Warrants and Placement Agent Warrants contain anti-dilution and price adjustment provisions, which may, under certain circumstances, (i) reduce the exercise price on several future dates according to a formula based on the then-current market price for our common stock and (ii) reduce the exercise price to match if we sell or grant options to purchase, including rights to reprice, our common stock or common stock equivalents at a price lower than the exercise price of the warrants, or if we announce plans to do so. The number of shares subject to warrants will not increase due to such reductions in exercise price. In connection with the sale of the Series C Preferred Shares, we entered into a Registration Rights Agreement (“RRA”) with the Purchasers, pursuant to which we filed a registration statement with the Securities and Exchange Commission (“SEC”) on March 20, 2015. It was declared effective by the SEC on April 8, 2015, which triggered the price adjustment provisions of the Series C Preferred Shares and the related warrants. As of that date, the conversion price of the Series C Preferred Shares was reduced to $0.142, the exercise price of the Series D and Series F Warrants was reduced to $0.1704, and the exercise price of the Series E Warrants and Placement Agent Warrants was reduced to $0.142. Accounting Treatment and Allocation of Proceeds Distinguishing Liabilities from Equity Derivatives and Hedging Debt The following is a summary of the allocation of the net proceeds from the preferred stock financing: Net proceeds after transaction costs $ 2,679,809 Less: Fair value of warrants (recorded to Additional Paid-in Capital) (1,695,868 ) Recorded value of Series C Preferred Shares at June 30, 2015 $ 983,941

Income Tax Disclosure [Text Block]	9. Income Taxes Because of our historically significant net operating losses, we have not paid income taxes since inception. We maintain deferred tax assets that reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. These deferred tax assets are comprised primarily of net operating loss carryforwards and also include amounts relating to nonqualified stock options and research and development credits. The net deferred tax asset has been fully offset by a valuation allowance because of the uncertainty of our future profitability and our ability to utilize the deferred tax assets. Utilization of operating losses and credits may be subject to substantial annual limitations due to ownership change provisions of Section 382 of the Internal Revenue Code. The annual limitation may result in the expiration of net operating losses and credits before utilization.
