PRESS RELEASE

MEDIMMUNE AND CRUCELL ANNOUNCE COLLABORATION TO DEVELOP NEW ANTIBODIES FOR THE
TREATMENT AND PREVENTION OF HOSPITAL-ACQUIRED BACTERIAL INFECTION

GAITHERSBURG, MD, USA AND LEIDEN, THE NETHERLANDS - OCTOBER 15, 2007 - MedImmune
and Crucell N.V. (Euronext, NASDAQ: CRXL) announced today that they have entered
into an exclusive license and research collaboration to further develop and
commercialize one of Crucell's panels of bacterial antibodies primarily for the
treatment and prevention of hospital-acquired bacterial infection.

Under the agreement, MedImmune is to provide Crucell certain upfront, annual and
milestone payments potentially exceeding US$ 40 million, plus research and
development (R&D) funding and an undisclosed royalty on product sales.

Under the terms of the agreement, Crucell has granted MedImmune an exclusive
license to research, develop and commercialize antibodies within one of its
MAbstract(R)-technology programs. In addition MedImmune will have access to
Crucell's antibody capabilities for further R&D.

The partnership combines Crucell's unique antibody discovery, research and
development capabilities with MedImmune's expertise in clinical development and
commercialization of anti-infective antibodies.

In 2005, Crucell announced the initiation of several new antibody discovery
programs in the field of hospital-acquired infections. Under the terms of the
license agreement announced today, Crucell has now entered into a partnership
with MedImmune for one of these programs. Crucell has discovered and developed
these unique anti-bacterial antibodies using its proprietary MAbstract(R)
technology.

"As a company strongly committed to the prevention of infectious disease, we are
excited to expand our research to include a broader program in bacterial
infection through this collaboration with Crucell," said JoAnn Suzich, Ph.D.,
MedImmune's senior director, infectious disease research.

"We are confident that this collaboration will accelerate the development of
this urgently needed therapeutic to circumvent antibiotic resistant infections
and we are immensely proud that MedImmune, a leader and innovator in the field
of infectious disease prevention, has chosen us as its partner," said Dr. Jaap
Goudsmit, CSO of Crucell. "This is an important validation of Crucell's
capabilities and potential in the development of novel therapeutic antibodies."


ABOUT MABSTRACT(R) TECHNOLOGY

Crucell's proprietary MAbstract(R) technology can be used to discover drug
targets, such as cancer markers or proteins from infectious agents including
bacteria and viruses, and to identify human antibodies against those drug
targets.


ABOUT HOSPITAL-ACQUIRED BACTERIAL INFECTIONS

In the U.S. and Europe, hospital-acquired bacterial infections affect about two
million patients per year, causing more than 200,000 deaths. Attributable costs
amount to more than US$ 5 billion per year in the U.S. alone.
Antibiotic-resistant bacteria increase the severity of disease, escalating
mortality rates and driving up costs. The rise in hospital-acquired infections
caused by antibiotic-resistant bacteria presents an opportunity for the
development of alternative treatments replacing or complementing antibiotics.

MedImmune strives to provide better medicines to patients, new medical options
for physicians and rewarding careers to employees. Dedicated to advancing
science and medicine to help people live better lives, the company is focused on
