CORRECTION - IMPACT OF DISCONTINUATION OF MERCK HIV STUDY ON CRUCELL'S PROSPECTS


LEIDEN, THE NETHERLANDS, SEPTEMBER 25 2007 - Dutch biotechnology company Crucell
N.V. (Euronext, NASDAQ: CRXL, Swiss Exchange: CRX) today stated that it wishes
to emphasize that the discontinuation of Merck's HIV phase I and II studys, as
announced on Friday September 21, is not related to the use of Crucell's
PER.C6(R) technology. The company further added that it reiterates its revenue
guidance for 2007 at (euro) 220 to 225 million.

"While the vaccine is produced on Crucell's PER.C6(R) technology, the
discontinuation of the study appears in no way related to the safety or efficacy
of the PER.C6(R) production technology and therefore has no impact on either
Crucell's licensing activities or Crucell's partnership with Merck with respect
to Crucell's PER.C6(R) and Advac(R) technologies as announced two weeks ago",
said Dr. Jaap Goudsmit, Crucell's Chief Scientific Officer. "We emphathize with
all people at risk of AIDS for whom this result is a set back."

Crucell also reiterates its revenue guidance of (euro) 220-225 million for 2007.
"We had not incorporated any income from the Merck HIV program in our guidance
for 2007. As the program was in a phase II study it was not at all expected to
enter the market within the next couple of years to generate royalty-based
income for Crucell. We therefore wish to emphasize that our guidance for 2007
has not changed as a result of this event," said Ronald Brus, Chief Executive
Officer. "Bringing an HIV vaccine to market has always been considered to be a
major challenge."
