Item 1 of the Statement is amended and supplemented as follows:   This Amendment No. 2 amends and supplements the statement on the Schedule 13D originally filed with the SEC on August 12, 2021 and amended on May 30, 2023 (the “Statement”) by RA Capital Management, L.P., Dr. Kolchinsky, Mr. Shah, and RA Capital Healthcare Fund, L.P. with respect to the common stock, $0.0001 par value per share (“Common Stock”), of Icosavax, Inc., a Delaware corporation (the “Issuer”), which has its principal executive offices at 1930 Boren Avenue, Suite 1000 Seattle, Washington 98101. Unless otherwise defined herein, capitalized terms use in this Amendment No. 2 shall have the meanings ascribed to them in the Statement. Unless amended or supplemented below, the information in the Statement remains unchanged.
Item 4.	Purpose of Transaction
Item 4 of the Statement is amended and supplemented as follows:   Merger Agreement and Related Transactions and Tender and Support Agreement   Pursuant to an Agreement and Plan of Merger, dated as of December 11, 2023 (the “Merger Agreement”), by and among the Issuer, AstraZeneca Finance and Holdings Inc. (“Parent”), a wholly owned subsidiary of AstraZeneca plc, and Parent’s wholly owned subsidiary, Isochrone Merger Sub Inc., prior to the Expiration Date (as defined in the Merger Agreement), each of the Reporting Person’s tendered all of their respective shares of Common Stock of the Issuer (the “Shares”) in the tender offer contemplated by the Merger Agreement. On February 19, 2024, at the effective time of the merger (the “Merger”) contemplated by the Merger Agreement (the “Effective Time”), these Shares were accepted in the tender offer in exchange for (i) $15.00 per Share, plus (ii) one non-tradable contingent value right (“CVR”) per Share, representing the right to receive a contingent payment of up to $5.00 in cash upon the achievement of specified milestones in accordance with the terms and subject to the conditions of a Contingent Value Rights Agreement.   Upon the closing of the Merger, Dr. Kolchinsky ceased to serve as a director of the Issuer. Also, as a result of the Merger, the Common Stock ceased to trade on the NASDAQ Global Select Market prior to the opening of trading on February 20, 2024, and became eligible for delisting from the NASDAQ Global Select Market and termination of registration pursuant to Rules 12g-4(a)(1) and 12h-3(b)(1)(i) of the Securities Exchange Act of 1934, as amended.

(3)

Pursuant to the Merger Agreement, each outstanding option to purchase Shares having an exercise price less than $15.00 per Share, whether or not vested, was cancelled and converted into the right to receive from the Surviving Corporation (as defined in the Merger Agreement) the following: (1) an amount in cash equal to the product obtained by multiplying (A) the aggregate number of Shares underlying such option immediately prior to the Effective Time, by (B) an amount equal to (I) $15.00, less (II) the exercise price of such option, plus (2) one CVR for each Share underlying such option.
