Item 1.	Security and Issuer
This statement on Schedule 13D relates to the Common Stock of the Company, and is being filed pursuant to Rules 13d-1 and 13d-5 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The address of the principal executive offices of the Company is 5800 Park of Commerce Boulevard, N.W., Boca Raton, FL 33487.

Item 2.	Identity and Background
This statement is being filed by David M. Knott, an individual whose business address is 485 Underhill Boulevard, Suite 205, Syosset, New York 11791. Mr. Knott is the managing member of Knott Partners Management, LLC, a New York limited liability company (“Knott Management”), that is the sole General Partner of Shoshone Partners, L.P., a Delaware limited partnership (“Shoshone”) and managing general partner of Knott Partners, L.P., a New Jersey limited partnership (“Knott Partners” and together with Shoshone, the “Partnerships”). The Partnerships invest in securities that are sold in public markets. The principal activity of each Partnership is the acquisition of long and short positions in equity securities of publicly traded U.S. and foreign securities. Each Partnership has the authority to employ various trading and hedging techniques and strategies in connection therewith. Mr. Knott is also the sole shareholder, Director and President of Dorset Management Corporation, a New York corporation (“Dorset”) which provides investment management services to a limited number of foreign and domestic individuals and entities (the “Managed Accounts”). The business address of Dorset is 485 Underhill Boulevard, Syosset, New York 11791. Collectively, Dorset and Mr. Knott are referred to as the Reporting Parties. During the last five years, Mr. Knott has not been convicted in any criminal proceeding, nor has he been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which he was or is subject to any judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws, or finding any violation with respect to such laws.

Item 3.	Source and Amount of Funds or Other Consideration
The source of funds used in making each of the purchases of the Common Stock purchased indirectly by Mr. Knott through the Partnerships and the Managed Accounts was the portfolio assets of the Partnerships and each of the Managed Accounts on whose behalf Mr. Knott has purchased the Common Stock. Neither of the Partnerships nor any of the Managed Accounts own more than five percent of the Common Stock individually. The aggregate amount of consideration used by the Reporting Parties in making such purchases was $28,735,985.

Mr. Knott effects purchases of securities primarily through margin accounts maintained by Goldman, Sachs & Co., which may extend margin credit as and when required to open or carry positions in the margin accounts, subject to applicable federal margin regulations, stock exchange rules, and the firm’s credit policies. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the accounts.

Item 4.	Purpose of Transaction
The Reporting Parties acquired the Common Stock for investment in the ordinary course of business. The Reporting Parties believe that the Common Stock at current market prices is undervalued and represents an attractive investment opportunity. The Reporting Parties may make further purchases of the Common Stock from time to time and may dispose of any or all of the Common Stock held by the Reporting Parties at any time. On April 19, 2006, following earlier discussions between representatives of the Reporting Parties and the Company regarding management’s plans for the Company, Anthony R. Campbell, a General Partner of Knott Partners Management, LLC sent a letter to Thomas H. McLain, the Chairman, President and Chief Executive Officer of the Company. The letter expressed the Reporting Parties belief that the Company should explore strategic alternatives and stated that the Company should begin the process by hiring an investment bank other than Lehman Brothers to explore such alternatives. The letter sent by the Reporting Parties is attached hereto as Exhibit A and is incorporated herein by reference. The Reporting Parties intend to continue discussions regarding these matters with management of the Company. Except as set forth herein, the Reporting Parties do not have any present plan or proposal that would relate to or result in any of the actions or transactions enumerated in clauses (a) through (j) of Item 4 of Schedule 13D. The Reporting Parties will amend this Schedule 13D as events unfold.

Item 5.	Interest in Securities of the Issuer

(a) Pursuant to Rule 13d-3, Mr. Knott may be deemed to own beneficially 5,662,900 shares of Common Stock, which represents 9.5% of all outstanding shares of Common Stock.

(b) Mr. Knott individually has the sole power to vote 5,216,400 shares of Common Stock and dispose of 5,562,400 shares of Common Stock held in the Partnerships’ accounts and the Managed Accounts. As President of Dorset, Mr. Knott shares with certain of Dorset’s clients the power to vote that portion of 285,200 shares of Common Stock held in their respective accounts. Mr. Knott also shares the power to vote 100,500 shares held by certain employees of Dorset.

None of the Partnerships or Managed Accounts (except through Mr. Knott) either holds or shares with any person the power to vote or to dispose of the Company’s Common Stock.

NABI Biopharmaceuticals

5800 Park of Commerce Blvd. NW

Dear Tom:

As you know, we have had three meetings with you over the past month, either in person or by telephone. We have listened carefully to your plans for NABI. Nonetheless we are not dissuaded from our belief that the shareholders of NABI would be best served if the company engages an investment banker to evaluate strategic alternatives for the company, including its possible sale.

From most shareholders’ perspectives, an investment in NABI has not been a profitable one. Indeed, the stock went public at $8.00 in 1969 and within the last three months traded at less than half that price. During the years of your management the company has on numerous occasions missed revenue projections and scientific milestones. In addition, it is our understanding that you have repeatedly ignored calls from major companies seeking to buy NABI. Why have you not, at least, listened to what they have to offer?

The shareholders of NABI have suffered enough. We strongly feel that now is the time that alternatives to the status quo must be considered. The first step in this process should be the hiring of an investment banker other than Lehman Brothers to seek ways to surface the value in NABI which we believe to be substantially higher than its present stock price.

	Yours truly,


	/s/ Anthony R. Campbell
