INDEPENDENT AUDITORS' REPORT



To the Savings and Investment Plan Committee
Pfizer Savings and Investment Plan:



We have audited the accompanying statements of net assets available for plan benefits of the Pfizer Savings and Investment Plan (the Plan) as of December 31, 2001 and 2000, and the related statements of changes in net assets available for plan benefits for the years then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform an audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits as of December 31, 2001 and 2000, and the changes in net assets available for plan benefits for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule H, line 4i - schedule of assets (held at end of year) and schedule H, line 4j - schedule of reportable transactions, as of and for the year ended December 31, 2001 are presented for the purpose of additional analysis and are not a required part of the basic financial statements but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. These supplemental schedules are the responsibility of the Plan's management. The supplemental schedules have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.

PFIZER SAVINGS AND INVESTMENT PLAN
NOTES TO FINANCIAL STATEMENTS
December 31, 2001 and 2000

Note 1 -Description of the Plan

General - The Pfizer Savings and Investment Plan (the Plan) is a defined contribution plan which was originally adopted by Pfizer Inc. (the Company) in 1965 as the Pfizer Savings Plan and has been amended from time to time since that date. Participation in the Plan is open to all eligible employees of the Company and any affiliate which, with the consent of the Company, adopts the Plan (Associate Companies). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended.

The following is a general description of certain provisions of the Plan. Participants should refer to the Plan document for more complete information.

Contributions - Each participant may make contributions on an after-tax basis and/or on a before-tax basis (that is, choose to reduce his or her compensation and have the Company contribute such amount to the Plan on his or her behalf). Contributions are subject to certain restrictions under the Internal Revenue Code of 1986, as amended. Contributions of up to 2% of compensation are matched 100% by the Company and the next 4% are matched 50%. Employee contributions in excess of 6% are not matched. Participants who are eligible employees are permitted to roll over into the Plan eligible distributions from other qualified employer sponsored savings plans and conduit IRAs.

Eligibility and Vesting - Generally, the domestic employees of the Company, except certain employees covered by a collective bargaining agreement, are eligible to enroll in the Plan on their date of hire. A participant is immediately vested in the full value of his or her account (i.e., participant's and employer's contributions).

Loans to Participants- Plan participants are permitted to borrow against their vested account balance. The minimum amount a participant may borrow is $1,000 and the maximum amount is the lesser of 50% of the vested account balance reduced by any current outstanding loan balance, or $50,000, reduced by the highest outstanding loan balance in the preceding 12 months.

Under the terms of the Plan, loans must be repaid within five years, unless the funds are used to purchase a primary residence. Primary residence loans must be repaid over 6 to 15 years at the participant's option. The interest rate on all loans is based on the prime rate plus 1%. Interest paid by the participant is credited to the participant's account.

Benefit Payments - Upon separation from service, retirement or disability, a participant may elect to receive a lump sum distribution currently or at any time up to the later of 13 months after termination or age 65, subject to the provisions of the Plan. In the event of a participant's death, a spouse beneficiary may elect payment currently or defer payments until the later of 13 months from date of death or when the participant would have reached age 65. A nonspouse beneficiary may defer payment up until 13 months from the date of death.

Withdrawals - A participant in the Plan may make withdrawals from his/her account balance subject to the provisions of the Plan.

Plan Termination - The Company expects to continue the Plan indefinitely, but reserves the right to amend, suspend or discontinue it in whole or in part at any time by action of the Company's Board of Directors. In the event of termination of the Plan, each participant shall be entitled to the full value of his or her account balance as though he or she had retired as of the date of such termination. No part of the invested assets established pursuant to the Plan will at any time revert to the Company.

Note 2 -Summary of Significant Accounting Policies

Basis of Accounting - The financial statements of the Plan are prepared on the accrual basis of accounting. For treatment of benefits payable, refer to Note 7.

Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the plan administrator to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, and the reported amounts of increases and decreases to net assets during the reporting period. Actual results could differ from those estimates.

Investment Valuation - Pfizer Inc. common stock is valued at the closing market price on the last business day of the year. U.S. Government securities are recorded at fair value based on market or dealer quotes on the last business day of the year. Collective index funds and the mutual fund are recorded at fair value based on the closing market prices of the underlying investments of the respective fund as of the last business day of the year. Loans to participants and short-term securities are recorded at cost which approximates fair value.

Loan Fund - The Loan fund maintains participant loan activity. Interest earned on participant loans is not included in this fund.

Risk and Uncertainties - Investment securities are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is possible that changes in their values could occur in the near term and such changes could materially affect the amounts reported in the Statement of Net Assets Available for Plan Benefits and the Statement of Changes in Net Assets Available for Plan Benefits.

Security Transactions - Purchases and sales of securities are reflected on a trade-date basis. Realized gains and losses on sales of investments represent the difference between the net proceeds and the cost of the investments (average cost if less than the entire investment is sold).

Unrealized Appreciation/(Depreciation) of Investments - Unrealized appreciation/(depreciation) of investments for the year represents the difference between the cost of the investments and their fair value at the end of the year. Additionally, it reflects the reversal of the unrealized appreciation/(depreciation) as of the end of the prior year.

Net Investment Income - Dividend income is recorded on the ex-dividend date. Interest income is recorded as earned. Interest income from participant loans is recorded by the Trustee as earned in the nonparticipant and participant directed funds in the same proportion as the original loan issuance.

Note 3 -Tax Status of the Plan

The Internal Revenue Service has determined and informed the Company that the Plan and related trust as of May 26, 1994 were designed in accordance with the applicable sections of the Internal Revenue Code. The Plan has been amended since receiving the determination letter and was submitted on February 28, 2002 for an updated determination letter. The Plan administrator and the Plan's legal and tax counsel believe that the Plan is designed and is currently being operated in material compliance with all the applicable requirements. Accordingly, no provision has been made for federal income taxes.

Contributions made to the Plan by the Company, including pre-tax contributions made on the participants' behalf and any appreciation on all funds in the participants' accounts, are not taxable to the participants under federal income tax law while these amounts remain in the Plan.

Note 4 - Administrative Costs

Except for certain member transfer costs and the investment management fees, all costs and expenses of administering the Plan are paid by the Company.

Note 5 -Realized Gains/(Losses) on Investments

The aggregate net proceeds and cost used in the calculation of the realized gains/(losses) on investments were as follows:

Note 7

For financial statement purposes, participant withdrawals and distributions are recorded when paid rather than when processed and approved for payment. Therefore, the net assets available for plan benefits as of December 31, 2001 and 2000 do not reflect a reduction for the following benefits payable to participants who had requested withdrawals as of December 31, but were not distributed until the subsequent year:



|(thousands of dollars)       | 2001            | 2000           
|---------------------------- | --------------- | ---------------
|                             |                 |                
|Nonparticipant directed fund | $ 7,033         | $14,200        
|Participant directed funds   | 9,450           | 16,557         
|                             | $16,483
======= | $30,757
=======

For the purposes of Form 5500, such withdrawals and distributions are recorded when processed and approved for payment. Therefore, benefits payable to participants who have requested withdrawals are reported as benefit expense on Form 5500 for those years.

Note 8 - Plan Merger and Modification

Effective February 1, 2002, most of the assets of the Warner-Lambert Savings and Stock Plan (WLSSP) and all of the assets of another Company plan, the Agouron Pharmaceuticals, Inc. 401(k) plan, totaling $1.83 billion were transferred into the Plan to create one harmonized savings plans for all eligible employees of the Company.
