VIREXX ANNOUNCES 2006 FISCAL YEAR RESULTS

EDMONTON, ALBERTA - March 23, 2007 - ViRexx Medical Corp. (TSX:VIR, AMEX:REX), a company focused on the development of immunotherapies for certain cancers, chronic hepatitis B & C and embolotherapy for tumors, announced its financial and operational results for the fiscal year ended December 31, 2006.

“The next twelve months will be a pivotal period for ViRexx as we expect to receive final data analysis from the two identical Phase III trials of OvaRex^® MAb and advance our Occlusin™ 500 Device into clinical trials in preparation for a 510(k) submission. With the countdown to the OvaRex^® MAb data in its final stages, ViRexx is among a select group of life sciences companies in North America expecting Phase III data within twelve months,” said Dr. Lorne Tyrrell, Chief Executive Officer and Chief Scientific Officer of ViRexx. “During the fourth quarter of 2006, ViRexx completed licensing, supply and manufacturing agreements for OvaRex^® MAb in the unlicensed European territories. ViRexx has established partnerships with Sigma-Tau, and its subsidiaries, and Dompé Farmaceutici, both successful marketers of specialty pharmaceutical products in Europe. These agreements represent access to 43% of the currently targeted ovarian cancer markets in North America and the European Union.”

Product Development Highlights

Enrollment was completed in the second of two identical OvaRex^® MAb Phase III trials for the treatment of late-stage ovarian cancer. The trials are being conducted by ViRexx’s licensee, Unither Pharmaceuticals, Inc. (Unither), a subsidiary of United Therapeutics Corporation. The primary endpoint for each trial is time-to-relapse comparing OvaRex^® MAb to placebo. The primary data analysis is scheduled and will occur after each trial has reported at least 118 relapse events. The first trial IMPACT I has achieved the 118^th event. It is projected that the second trial, IMPACT II, will reach the 118^th event in the second half of 2007.

ViRexx’s licensee, Unither, completed enrollment in a 40 patient OvaRex^® MAb Phase II trial, designed to study its use as an adjunct to platinum-based front line chemotherapy in the treatment of advanced ovarian cancer. Unither will present the results at the American Society of Clinical Oncology (ASCO) in June of 2007.

ViRexx International Corp. and Defiante Farmaceutica, Lda. and Tecnogen S.C.p.A., both subsidiaries of Sigma-Tau Pharmaceuticals, Inc. of Rome, Italy, completed manufacturing, licensing and distribution agreements for OvaRex^® MAb for the remaining unlicensed European territories which include the UK, Ireland, France, Sweden, Finland and other countries. The agreements provide for ViRexx to receive a net effective royalty of approximately 25% on net sales of OvaRex^® MAb in the European and Middle Eastern countries and milestone payments of up to Cdn$6.5 million in equity. The milestone payments included an advanced equity investment of Cdn$2.0 million from Sigma-Tau and its subsidiaries for 1,818,182 units of ViRexx at a price of Cdn$1.10.

A Phase I safety trial of HepaVaxx B Vaccine was completed. The trial enrolled and treated its target of 15 healthy volunteers with a single dose subcutaneous injection of the vaccine; no significant adverse events associated with the treatment have been reported. ViRexx is continuing to monitor the volunteers and expects to complete this safety assessment by the second quarter of 2007.

·	The Company entered into a research collaboration with Defense Research and Development Canada - Suffield to evaluate the use of the Chimigen™ vaccine platform for biodefense applications.

·	Enrollment and treatment for the Phase I trial of Occlusin™ 50 Injection in liver cancer patients at the Foothills Hospital in Calgary and the Toronto General Hospital was completed during the year.

Financial Highlights

(All amounts reported are in Canadian dollars unless otherwise stated)

The Company recorded a net loss for the twelve-month period ended December 31, 2006 of $17,493,375 or $0.25 per share, as compared with a net loss of $7,459,714 or $0.13 per share for the twelve-month period ended December 31, 2005. Approximately 75% of the change in the Company’s net loss for the year ended December 31, 2006 is due to a non-cash change in the net future tax expense associated with the transfer of intellectual property to ViRexx International Corp.

Research and development expenses for the twelve-month period ended December 31, 2006 were $5,937,122, compared with $4,750,190 for the twelve-month period ended December 31, 2005. The difference is primarily due to additional toxicology testing for the HepaVaxx B Vaccine clinical studies and product development and manufacturing costs associated with the Occlusin™ 500 Device.

Corporate Administration expenses for the twelve-month period ended December 31, 2006 were $4,976,837, compared with $3,650,282 for the twelve-month period ended December 31, 2005. The difference is primarily due to expenses related to business development and commercialization activities for OvaRex^® MAb in Europe and business development for the T-ACT™ and Chimigen™ technologies. Corporate Administration also includes consulting and other fees associated with the new 52-109 and SOX compliance requirements, as well as restructuring costs relating to ViRexx’s announcement on November 26, 2006 to prioritize its research activities to focus on the completion of its existing pipeline products that provide near-term potential revenue streams.

At December 31, 2006, the Company’s cash and short term investments totalled $10,742,191 as compared to $5,571,850 at December 31, 2005. During the twelve-month period ended December 31, 2006, the Company raised $15,000,000 from the completion of three separate private placements.

At December 31, 2006, the Company had 72,760,717 common shares outstanding. The number of stock options and warrants outstanding at December 31, 2006 is 6,396,241 and 17,077,471, respectively, and could generate proceeds of $29,931,775 if exercised.
