Report of Independent Accountants

To the Board of Trustees of Vanguard Variable Insurance Funds

We have examined management's assertion, included in the accompanying Management Statement Regarding Compliance with Certain Provisions of the Investment Company Act of 1940, that the funds listed within Attachment A (the "Funds") complied with the requirements of subsections (b) and (c) of Rule 17f-2 under the Investment Company Act of 1940 ("the Act") as of July 25, 2024. The Funds' management is responsible for its assertion and the Funds' compliance with those requirements. Our responsibility is to express an opinion on management's assertion about the Funds' compliance with the specified requirements based on our examination.

Our examination was conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States) and in accordance with attestation standards established by the American Institute of Certified Public Accountants. Those standards require that we plan and perform the examination to obtain reasonable assurance about whether management's assertion about compliance with the specified requirements is fairly stated, in all material respects, and, accordingly, included examining, on a test basis, evidence about the Funds' compliance with those requirements and performing such other procedures as we considered necessary in the circumstances. Included among our procedures were the following tests performed as of July 25, 2024, and with respect to agreement of security purchases and sales, for the periods noted within Attachment A:

-	Confirmation of all securities held on VAST, the recordkeeping system used by the Funds' transfer agent, in book entry form without prior notice to management;

-	Reconciliation of all such securities to the books and records of the Funds and VAST; and

-	Agreement of 2 security purchases and 2 security sales or maturities per fund (when 2 or less security purchases or 2 or less security sales per fund are available, agreement of all possible security purchases or all possible security sales per fund) from the books and records of the Funds to VAST.

We believe that our examination provides, and that the evidence we obtained is sufficient and appropriate to provide, a reasonable basis for our opinion. Our examination does not provide a legal determination on the Funds' compliance with the specified requirements.

We are required to be independent and to meet our ethical responsibilities in accordance with relevant ethical requirements related to the engagement.

In our opinion, management's assertion that the Funds complied with the requirements of subsections (b) and (c) of Rule 17f-2 of the Investment Company Act of 1940 as of July 25, 2024 with respect to securities reflected in the investment accounts of the Funds is fairly stated, in all material respects.

This report is intended solely for the information and use of management and the Board of Trustees of the Funds and the Securities and Exchange Commission and is not intended to be and should not be used by anyone other than the specified parties.
