Re: Registration Statement of Viveon Health Acquisition Corp.

Ladies and Gentlemen:

We have acted as special counsel to Viveon Health Acquisition Corp. (“VHAQ”), a Delaware corporation, in connection with the preparation of a registration statement on Form S-4, File No. 333-266123 (the “Registration Statement”), filed by VHAQ with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), in connection with the offer and sale to the security holders of Suneva Medical, Inc., a Delaware corporation (“Suneva”), in a business combination transaction (the “Business Combination”) pursuant to that certain agreement and plan of merger, dated as of January 12, 2022, (the “Merger Agreement”), by and among Suneva, VHAQ, and Viveon Health Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of VHAQ (“Merger Sub”) of up to (i) 36,594,010 shares (the “VHAQ Shares”) of common stock, par value $0.0001 per share (the “Common Stock”), of VHAQ, to be issued to security holders of Suneva, inclusive of 12,000,000 shares of Common Stock issuable pursuant to certain earn-out triggers described in the proxy statement/prospectus constituting part of the Registration Statement, and (ii) 664,198 shares (the “Option Shares”) of Common Stock underlying the Suneva stock options converted in the Business Combination into options to purchase Common Stock (the “Options”).

We have examined such documents and considered such legal matters as we have deemed necessary and relevant as the basis for the opinion set forth below. With respect to such examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as reproduced or certified copies, and the authenticity of the originals of those latter documents. As to questions of fact material to this opinion, we have, to the extent deemed appropriate, relied upon certain representations of certain officers of VHAQ.
