             period.

          -  Chronic administration (defined as more than 14 days) of immunosuppressants or other
             immune-modifying drugs within six months prior to vaccination. (For corticosteroids,
             this will mean prednisone <10 mg/day, or equivalent, is allowed. Inhaled and topical
             steroids are allowed.)

          -  Planned administration/administration of a vaccine not foreseen by the study protocol
