Crucell narrowed the range for its revenue guidance for the year, which it now expects to be in the €140 million to €150 million range. Fourth quarter revenues are expected to be strong due to strong influenza vaccine sales, which are concentrated in the fourth quarter due to the late start of the influenza season this year.
