General
The financial information presented as of March 31, 2001 is unaudited. In the opinion of the Company's management, the financial
information presented herein contains all adjustments (which consist only of normal recurring adjustments) necessary for a fair
presentation of results for the interim periods presented. Interim results are not necessarily indicative of results for an entire
year or for any subsequent interim period. These consolidated financial statements should be read in conjunction with the Company's
annual report on Form 10-K for the year ended December 31, 2000.

Derivative Instruments and Hedging Activities

The Company adopted Financial Accounting Standards No. 133 (FAS 133), "Accounting for Derivative Instruments and Hedging
Activities", on January 1, 2001. In accordance with the transition provisions of FAS 133, the Company recorded a net-of-tax
cumulative-effect-type adjustment of $0.3 million in accumulated other comprehensive income to recognize at fair value all
derivatives that are designated as foreign currency cash-flow hedging instruments. Net gains or losses on derivatives that had been
previously deferred were immaterial.

The Company purchases inventory from a foreign vendor and pays the vendor in a foreign currency. This exposes the Company to foreign
currency exchange rate risk, which is monitored by the Company as part of its overall risk-management program. There are no other
significant sources of foreign currency exchange risk. The Company maintains a foreign-currency risk-management strategy that uses
derivative instruments to protect its interests from unanticipated fluctuations in earnings and cash flows caused by volatility in
currency exchange rates. The Company uses foreign-currency forward-exchange contracts to hedge these risks.

The Company accounts for its derivatives as foreign-currency cash-flow hedges. The Company is required to recognize any
ineffectiveness on hedging transactions as interest income or expense in the statement of operations. For the quarter ended March
31, 2001, gains or losses for ineffective hedges were insignificant. The Company did not reclass any material gains or losses to
interest income in the statement of operations as a result of the discontinuance of foreign currency cash-flow hedges related to
certain forecasted transactions that are now probable of not occurring. As of March 31, 2001, $0.1 million of deferred losses on
derivative instruments accumulated in other comprehensive income are expected to be reclassified to earnings in the next twelve
months in conjunction with the sale of the related inventory. The maximum term over which the Company is hedging exposures to the
variability of cash flows is twelve months.





Inventory
Inventory, net of reserves, is comprised of the following (in thousands):

                                                   =======          ========


In December 2000, the Company received approval from the FDA to perform a portion of the CytoGam production process at the Company's
Frederick manufacturing facility. As a result, all work in process inventory of CytoGam is classified as a current asset as of
December 31, 2000. Noncurrent inventory is comprised of some of the Company's raw plasma.

As a result of the June 1998 FDA approval of Synagis and the market acceptance of Synagis, the Company reserved approximately $9.2
million against its RespiGam inventory as minimal product sales were expected to result from this inventory in the foreseeable
future. RespiGam reserve balances at March 31, 2001 and December 31, 2000 were $4.7 million.

Earnings per Share
The Company computes earnings per share in accordance with Statement of Financial Accounting Standards No. 128, "Earnings Per
Share." Basic earnings per share is computed based on the weighted average number of common shares outstanding during the period.
Diluted earnings per share is computed based on the weighted average shares outstanding and the dilutive impact of common stock
equivalents outstanding during the period, as measured by the treasury stock method. Common stock equivalents are not included in
periods where there is a loss as they are anti-dilutive. The following is a reconciliation of the denominator of the diluted EPS
computation for the periods reported. There are no reconciling items to the numerator for the EPS computation for the periods
reported.

Options to purchase 6,710,375 shares of common stock with prices from $45.00 to $83.25 per share were outstanding in the first
quarter of 2001 and options to purchase 4,386,225 shares of common stock with prices from $56.33 to $67.98 per share were
outstanding in the first quarter of 2000; these shares were not included in the computation of diluted earnings per share because
they were anti-dilutive.

Income Taxes
Income tax as a percentage of pre-tax income for the three months ended March 31, 2001 was 35.5%. During the quarter ended March 31,
2001, the Company recognized credits for research and development expenditures and credits earned for Orphan Drug status of certain
research and development expenses, resulting in a reduction from the statutory rate of 38.6%.

Comprehensive Income
Comprehensive income is comprised of net income and other comprehensive income. Other comprehensive income includes certain changes
in equity that are excluded from net income, such as translation adjustments, unrealized holding gains and losses on
available-for-sale marketable securities, and gains and losses on hedging instruments.

Comprehensive income for the three months ended March 31, 2001 was $74.8 million versus $30.5 million for the comparable period in
2000. A significant portion of other comprehensive income/(loss) for the three months ended March 31, 2001 relates to unrealized
holding losses on available-for-sale marketable securities. The Company maintains an investment in a company with which it had
previously formed a strategic alliance. Due to market volatility associated with the per share price of this investment, the value
of the Company's investment fluctuated significantly during the quarter and may continue to do so in the future.

Stock Split
On February 17, 2000, the Company's Board of Directors declared a three-for-one stock split effected in the form of a 200% stock
dividend payable to shareholders of record on June 2, 2000. All share, per share and weighted average share amounts for 2000 have
been restated to reflect this stock split.

                                                           ======          ======


Product sales increased 20% to $235.2 million in first quarter 2001, versus $195.8 million in first quarter 2000, driven by
increased sales of Synagis. Sales of Synagis grew 26% from sales in the comparable quarter of 2000, comprised of a 23% increase in
domestic sales and a 109% increase in international sales. The domestic sales increase results from a 21% increase in units sold to
wholesalers and distributors, reflecting increased demand for the product, as well as a 3% price increase which took effect during
the second quarter of 2000. End-user demand for Synagis in the United States (reflecting sales by wholesalers and distributors to
physicians, hospitals and clinics) increased an estimated 44% for the first quarter of 2001 as compared to the 2000 quarter. The
difference between sales by the Company and end-user sales reflects fluctuations in inventory held at the wholesalers and
distributors. The Company's international sales of Synagis increased primarily due to an 84% increase in units sold to Abbott
Laboratories, the Company's exclusive distributor of Synagis outside of the United States, and totaled $9.4 million in the 2001
quarter versus $4.5 million in the 2000 quarter. End-user demand for Synagis outside of the United States grew an estimated 71% to
$18.1 million for the 2001 first quarter over the comparable 2000 quarter, due to additional regulatory, pricing and reimbursement
approvals in overseas countries. The terms of the Company's agreement with Abbott provide for the Company to receive 40 to 50
percent of end-user sales. The Company initially recognizes sales to Abbott when Synagis is shipped to Abbott based on a
contractual, guaranteed transfer price; this amount approximates 60 to 75 percent of the total sales revenue the Company expects to
receive for each vial. Following the end of each quarter, Abbott remits to the Company a report detailing end-user sales for the
quarter and the Company recognizes revenue for the additional amount due in excess of the transfer price and up to 40 to 50 percent
of the end-user selling price.

The Company's worldwide sales of CytoGam decreased 21% from the first quarter of 2001 as compared to the first quarter of 2000. This
decrease was driven primarily by a decrease in domestic sales of 33%, partially offset by a $1.1 million increase in international
sales of CytoGam for the 2001 first quarter, due to an increase in units sold. The Company believes that a portion of the CytoGam
sales that occurred in the 2000 quarter were the result of product substitution occurring because of the worldwide shortage of
standard IVIG products. During 2000, the supply of standard IVIG products increased, and certain Medicaid agencies began to limit or
discontinue reimbursement of CytoGam as a substitute for IVIG. Thus, CytoGam sales for the three-month period ended March 31, 2001
relating to product substitution have decreased significantly. The Company expects that the future use of CytoGam as a substitute
for standard IVIG products will be limited. Sales of Ethyol to the Company's domestic and international distribution partners
decreased by 34% in the 2001 quarter versus the 2000 quarter. The Company believes this decrease is reflective primarily of
fluctuations in inventory stocking levels at the Company's distribution partners. First quarter 2001 domestic end-user sales of
Ethyol increased 9%, while international end-user sales were consistent with 2000 levels. In April of 2000, ALZA exercised a
one-time option under the distribution agreement to extend its rights to distribute Ethyol in the United States until April 2002. In
April 2002, the rights to distribute Ethyol will return to the Company and ALZA will receive a royalty from the Company for nine
years thereafter based on sales of Ethyol in the United States. Sales of other products in first quarter 2001 decreased $2.2
million, or 48% from the prior year quarter. Sales of other products include primarily sales of NeuTrexin and RespiGam. Also
included in 2000 other product sales are sales of Hexalen. In November 2000, the Company sold this product to MGI Pharma.

Other revenues for first quarter 2001 were $10.0 million compared to $9.7 million for first quarter 2000. Included in other revenue
are revenues recognized in accordance with the adoption of Securities and Exchange Commission Staff Accounting Bulletin No. 101 (SAB
101) effective January 1, 2000. The SAB requires that the revenue received in conjunction with up-front or milestone payments be
recognized over the remaining performance period under the contract as those contractual obligations are fulfilled. Accordingly,
other revenues in both the 2001 and 2000 periods include revenues related to up-front fees and milestone payments received prior to
2000. The Company recognized revenue of $5.5 million for the first quarter of 2001 and $7.2 million for the first quarter of 2000
resulting the adoption of SAB 101. Other revenue for the 2001 quarter also includes amounts relating to the Company's sale of
Hexalen, funding earned under a collaborative agreement with GlaxoSmithKline (GSK) for HPV vaccine development, and royalty income
due from ALZA in accordance with the terms of the Ethyol distribution agreement. Other revenue in the 2000 quarter also includes
funding earned under the collaborative HPV agreement with GSK.

Cost of sales rose 17% for the first quarter of 2001 to $52.8 million versus $45.0 million in 2000. This increase is primarily a
result of the increase in 2001 sales volumes. Gross margins were 78% in first quarter 2001, as compared to 77% for the first quarter
of 2000. The Company expects gross margins to vary from quarter to quarter, based on the product mix. In addition, the Company
expects that on an annual basis for 2001, gross margins will modestly improve from 2000 levels.

Research, development and clinical spending increased 21% over the prior year quarter from $15.5 million in 2000 to $18.7 million in
2001, primarily due to higher expenditures on the Company's clinical trials. The Company is currently administering multiple trials
for its products, including a Phase IV trial for Synagis in infants with congenital heart disease, two Phase II human papillomavirus
vaccine trials, one Phase I trial and two Phase II trials for use of MEDI-507 in psoriasis patients, and two Phase II trials for its
urinary tract infection (UTI) vaccine. The Company expects clinical spending levels to continue to increase in the coming quarters
as the Company moves its product candidates into the clinic and expands the number of trials for certain products already in the
clinic.

Selling, general and administrative (SG&A) expense was $59.7 million in 2001 versus $50.7 million in 2000, an increase of 18%. A
significant portion of the increase in SG&A expense in the 2001 first quarter relates to co-promotion expenses due to the Ross
Products Division of Abbott Laboratories for the promotion of Synagis in the United States; these expenses increase as the domestic
sales for Synagis increase. Co-promotion expense is recorded ratably as a percentage of net domestic Synagis sales. Further
increases in 2001 were attributable to the establishment of the Company's pediatric sales force during mid-year 2000. As a
percentage of product sales, SG&A expenses in the 2001 period were 25%, versus 26% of product sales in the 2000 period.

Other operating expenses, which reflect manufacturing start-up costs, decreased in first quarter 2001 to $2.1 million from $2.3
million in first quarter 2000. In December 2000, the FDA granted approval for an amendment to the Biologic License Application for
CytoGam to allow for a portion of the production of CytoGam at the Company's Frederick facility. Currently, the plasma production
section of the Frederick facility has excess capacity. Other operating expenses are expected to continue for the foreseeable future
until the plasma production section of the facility is fully utilized for its intended purpose.

Interest income almost doubled to $10.2 million from $5.2 million in the 2000 quarter as a result of higher cash balances available
for investment, offset by a decrease in interest rates, which lowered the yield on the Company's 2001 investment portfolio.

The Company recorded a provision for income taxes in first quarter 2001 of $43.3 million as compared to $34.7 million in the prior
year quarter. The Company's effective tax rate for the 2001 quarter was 35.5% as compared to 35.7% for the 2000 quarter. The
variation in both quarters from the statutory rate of 38.6% is principally due to credits for research and development expenditures
and credits earned for orphan drug status of certain research and development activities. The Company expects that its effective tax
rate in future periods will be slightly below or approximate to the applicable statutory rates.

The Company recorded a non-cash charge to 2000 earnings of $33.8 million, net of tax, or $0.16 on a per share basis, as the
cumulative effect of a change in accounting principle for the implementation of SAB 101. The adjustment was applied to the first
quarter of 2000 as required by the SAB and includes amounts recognized as revenue prior to 2000 relating to up-front payments or
milestone payments received by the Company in prior years under arrangements for which performance obligations related to the
up-front or milestone payments had been met, but for which the Company is contractually obligated to perform additional research and
development activities or other activities in future periods. Generally accepted accounting principles previously required the
Company to record the revenue from the up-front and milestone payments as received, when the performance obligations associated with
those payments had been fully met. However, following the adoption of the SAB, generally accepted accounting principles now require
that the revenue received in conjunction with up-front or milestone payments be recognized over the remaining performance period
under the contract as those obligations are fulfilled.

Net earnings for the first quarter of 2001 were $78.7 million and increased 26% when compared to first quarter 2000 earnings before
the cumulative effect of a change in accounting principle of $62.4 million. Net earnings for the 2000 period were $28.6 million.
Basic earnings per share in 2001 of $0.37 on 212.2 million shares compared to basic earnings per share (including the cumulative
effect of a change in accounting principle) of $0.14 in 2000 on 205.9 million shares. Diluted earnings per share in 2001 of $0.36 on
219.8 million shares compared to diluted earnings per share in 2000 (including the cumulative effect of a change in accounting
principle) of $0.13 on 218.7 million shares. Share and per share amounts in 2000 have been restated to reflect the three-for-one
stock split effected in June 2000.

Quarterly financial results may vary significantly due to seasonality of Synagis product sales, fluctuations in sales of other
products, milestone payments, research funding and expenditures for research, development, clinical and marketing programs. Synagis
sales are expected to occur primarily during, and in proximity to, the RSV season, which typically occurs between October and April
in the United States. No assurances can be given that adequate product supply will be available to meet demand.

LIQUIDITY AND CAPITAL RESOURCES

Cash and marketable securities at March 31, 2001 were $660.4 million compared to $526.3 million at December 31, 2000. Working
capital increased to $662.7 million at March 31, 2001 versus $536.3 million at December 31, 2000. Net cash provided by operating
activities in the three months ended March 31, 2001 was $130.6 million, reflecting net income for the period and increases in
accrued expenses, primarily as a result of amounts due to Abbott for co-promotion of Synagis, offset by an increase in accounts
receivable. Outflows for investing activities for the three months ended March 2001 included capital expenditures of $2.1 million,
increases in investments of $22.9 million, and $1.5 million for an investment in a collaborative partner. During the three months
ended March 31, 2001, stock option exercises provided $9.3 million of cash, compared to $50.8 million in the 2000 quarter.

The Company believes that its existing funds at March 31, 2001, together with funds expected to be generated from product sales and
investment income, will provide sufficient liquidity to meet the anticipated needs of the business for the foreseeable future,
absent the occurrence of any unforeseen events.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Disclosures About Market Risk" of the Company's Annual Report on Form 10-K for the year ended December 31, 2000.

                                                     --------------------

The statements in this quarterly report that are not descriptions of historical facts may be forward-looking statements. Those
statements involve substantial risks and uncertainties. You can identify those statements by the fact that they contain words such
as "anticipate," "believe," "estimate," "expect," "intend," "project" or other terms of similar meaning. Those statements reflect
management's current beliefs, but are based on numerous assumptions which MedImmune can not control and which may not develop as
MedImmune expects. Consequently, actual results may differ materially from those projected in the forward-looking statements. Among
the factors that could cause actual results to differ materially are: Seasonal demand for and continued supply of our principal
product; availability of competitive products in the market; availability of third-party reimbursement for the cost of our products;
effectiveness and safety of our products; exposure to product liability, intellectual property or other types of litigation; foreign
currency exchange rate fluctuations; changes in generally accepted accounting principles; growth in costs and expenses; the impact
of acquisitions, divestitures and other unusual items; and the risks, uncertainties and other matters discussed elsewhere in this
quarterly report and in our periodic reports filed with the U.S. Securities and Exchange Commission. MedImmune cautions that RSV
disease occurs primarily during the winter months; MedImmune believes its operating results will reflect that seasonality for the
foreseeable future. MedImmune is also developing several products for potential future marketing. There can be no assurance that
such development efforts will succeed, that such products will receive required regulatory clearance or that, even if such
regulatory clearance were received, such products would ultimately achieve commercial success. Unless otherwise indicated, the
information in this quarterly report is as of March 31, 2001. This quarterly report will not be updated as a result of new
information or future events.

                                                               OTHER INFORMATION

Item 1.           Legal Proceedings

In 1998, MediGene AG initiated a legal action against Loyola University of Chicago and the Company in the U.S. District Court for
the Northern District of Illinois alleging, among other things, breach of contract and tortious interference by the Company with an
alleged prospective business relationship between MediGene and Loyola. The claims related to human papillomavirus vaccine technology
allegedly covered by contracts between MediGene and the Company and by a license agreement from Loyola to the Company, under which
the Company granted a sublicense to GlaxoSmithKline. MediGene claimed monetary damages from the Company and ownership of the patents
in question, as well as rescission of the Company's license agreement from Loyola or rights as a third-party beneficiary thereof. In
November 2000, MedImmune and Loyola moved for summary judgment seeking dismissal of all claims. In December 2000, the District Court
granted partial summary judgment in favor of the defendants and reserved ruling on the remaining claims pending additional briefing
and a hearing scheduled for March 12, 2001. Following that hearing, on March 15, 2001, the District Court granted summary judgment
in favor of MedImmune on all remaining claims.

In October 2000, Celltech Chiroscience Limited ("Celltech") commenced a legal proceeding against the Company in the U.K. High Court
of Justice, Chancery Division, Patents Court. Celltech alleges that the Company failed to pay royalties with respect to its sales of
Synagis as required by a license agreement dated January 19, 1998. Under the agreement, the Company obtained from Celltech a
worldwide license to make, use and/or sell product under a patent (and related applications) pertaining to humanized antibodies. In
the proceeding, Celltech seeks payment of royalties, with interest, and certain costs, including attorney's expenses. The Company
has filed answering papers denying that any royalties are due on the basis that Celltech's patent does not cover Synagis and has
sought dismissal of the case on the grounds that the legal doctrine of prosecution history estoppel prevents Celltech from claiming
that its patent covers Synagis. The court has scheduled a hearing on June 5, 2001 to determine whether to dismiss the case on this
basis.

On February 28, 1996, Ichthyol Gesellschaft Cordes, Hermanni & Co. ("Ichthyol Gesellschaft") filed a complaint for refrain,
information and damages with the Regional Court of Hamburg against U.S. Bioscience, Inc. (acquired in November 1999) on the grounds
of trademark infringement in respect of the use of the trademark "Ethyol" in Germany. The suit was dismissed on January 29, 1997 by
the Regional Court of Hamburg at which time Ichthyol Gesellschaft was given leave to appeal against the judgment rendered in favor
of U. S. Bioscience. Ichthyol Gesellschaft filed an appeal, and a judgment was rendered in favor of U.S. Bioscience in the appellate
proceedings. In January 1999, Ichthyol Gesellschaft filed an appeal on points of law with the Federal Court of Justice, and in June
1999, Ichthyol Gesellschaft filed the grounds for the appeal on points of law. In October 1999, the Federal Court of Justice
accepted Ichthyol Gesellschaft's appeal and a hearing was scheduled for May, 2001. It is not possible to predict the decision of the
Federal Court of Justice with respect to the matter.

After consultation with its counsel, the Company believes that it has meritorious defenses to the claims referred to above and it is
determined to defend its position vigorously. While it is impossible to predict with certainty the eventual outcome of these
proceedings, the Company believes they are unlikely to have a material adverse effect on its financial position but might have a
material adverse effect on its results of operations for a particular period.
