Summary of Significant Accounting Policies [Abstract]
Basis of Presentation	Basis of presentation The accompanying interim unaudited condensed consolidated financial statements have been prepared using generally accepted accounting principles in the United States of America (GAAP) and pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”) for interim financial reporting. The unaudited condensed consolidated financial statements for the periods presented include the accounts of UNS and COVAXX that were parties to the Contribution and Exchange Agreement. All share and per share amounts, as originally recorded by each entity, have been converted to a number of shares and per share amounts using the conversion ratios determined under the Contribution and Exchange Agreement and the Stock Split ratio. These interim condensed consolidated financial statements are unaudited and, in the opinion of management, include all adjustments (consisting of normal recurring adjustments and accruals) necessary to fairly present the results of the interim periods. The condensed consolidated balance sheet at December 31, 2021, has been derived from the audited financial statements at that date. Operating results for the three and six months ended June 30, 2022 and cash flows for the six months ended June 30, 2022 are not necessarily indicative of the results that may be expected for the fiscal year ended December 31, 2022 or any other future period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been omitted in accordance with the rules and regulations for interim reporting of the SEC. These interim unaudited condensed financial statements should be read in conjunction with the financial statements and notes thereto included in our report for the year ended December 31, 2021. Leases At inception of a contract, we determine whether an arrangement is or contains a lease. For all leases, we determine the classification as either operating leases or financing leases. Operating leases are included in Operating lease right-of-use assets and Operating lease liabilities in our Condensed Consolidated Balance Sheets. Lease recognition occurs at the commencement date and lease liability amounts are based on the present value of lease payments over the lease term. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. If a lease does not provide information to determine an implicit interest rate, we use our incremental borrowing rate in determining the present value of lease payments. Right-of-use (ROU) assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments under the lease. ROU assets also include any lease payments made prior to the commencement date and exclude lease incentives received. Operating lease expense is recognized on a straight-line basis over the lease term. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Lease agreements with both lease and nonlease components, are generally accounted for together as a single lease component. The Company has elected to apply the short-term expedient to leases with a lease term of 12 months or less, which does not subject the leases to capitalization. Related party transactions The Company has a Related Party policy which defines related parties, and assigns oversight responsibility for related party transactions to the Company's Audit Committee. The Committee reviews in advance related party transactions, and considers multiple factors, including the proposed aggregate value of the transaction, or, in the case of indebtedness, the amount of principal that would be involved, the benefits to the Company of the proposed transaction, the availability of other sources of comparable products or services, and an assessment of whether the proposed transaction is on terms that are comparable to the terms available to or from, as the case may be, unrelated third parties. Under the policy, related party transactions are approved only if the Committee determines in good faith that the transaction is not inconsistent with the interests of the Company and its shareholders. Significant accounting policies The significant accounting policies used in preparation of these unaudited condensed consolidated financial statements are disclosed in our annual financial statements for the year ended December 31, 2021. There have been no changes to the Company’s significant accounting policies during the three and six months ended June 30, 2022. Recently issued accounting pronouncements From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption. Recently adopted accounting standards In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”). ASU 2018-11 provided an alternative method in addition to the modified retrospective transition method for ASU No. 2016-02, Leases: Amendments to the FASB Accounting Standards Codification (“ASU 2016-02”), issued in February 2016. Under ASU 2018-11, an entity may elect to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of

Recently Adopted and Issued Accounting Pronouncements	Recently issued accounting pronouncements From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption. Recently adopted accounting standards In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”). ASU 2018-11 provided an alternative method in addition to the modified retrospective transition method for ASU No. 2016-02, Leases: Amendments to the FASB Accounting Standards Codification (“ASU 2016-02”), issued in February 2016. Under ASU 2018-11, an entity may elect to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Under ASU 2016-02, a lease is required to recognize assets and liabilities with lease terms of more than twelve months. ASU 2016-02 is effective for nonpublic business entities and public entities eligible to be Smaller Reporting Companies for fiscal years beginning after December 15, 2021. The Company adopted the new standard on January 1, 2022 using the modified retrospective approach. The Company has elected to apply the transition method that allows companies to continue applying the guidance under the lease standard in effect at that time in the comparative periods presented in the condensed financial statements and recognize a cumulative-effect adjustment to the opening balance of accumulated deficit on the date of adoption. The Company has elected to combine lease components (for example fixed rent payments) with non-lease components (for example, common-area maintenance costs) on our facility, lab equipment and CRO embedded lease asset classes. The Company also elected the “package of practical expedients”, which permits the Company not to reassess under the new standard the Company’s prior conclusions about lease identification, lease classification and initial direct costs. In addition, the Company also elected the short-term lease practical expedients allowed under the standard. Lastly, the Company did not elect the practical expedient allowing the use-of-hindsight which would require the Company to reassess the lease term of its leases based on all facts and circumstances through the effective date. Results for reporting period beginning after January 1, 2022 are presented under the new standard, while prior period amounts are not adjusted and continue to be reported under the accounting standards in effect for the prior period. Upon adoption of the new lease standard, on January 1, 2022, the Company was not entered into any leases subject to ASC 842 and did not capitalize a ROU asset or lease liability.
