ID Biomedical Provides Update on Vaccine Development Programs

Vancouver, BC — October 24, 2005 — ID Biomedical Corporation (TSX: IDB; NASDAQ: IDBE) today provided an update on two of its lead vaccines in clinical development: FluINsure™, a non-living intranasally delivered influenza vaccine, and StreptAvax™, a subunit protein-based vaccine against group A streptococcal diseases.
ID Biomedical announced that it has obtained clearance from Health Canada to begin the first pediatric study of the FluINsure vaccine. This Phase II study will be conducted at three centers in Canada in 160 healthy children, aged 3 to 12 years old. The study will be blinded, randomized, and placebo-controlled and will evaluate safety and immunogenicity of one-dose and two-dose regimens of the vaccine. Enrollment for the study has begun.
The Company also announced that it recently held a pre-Investigational New Drug (“IND”) meeting with the U.S. Food and Drug Administration (“FDA”) regarding the pediatric development program for its StreptAvax vaccine. At the pre-IND meeting, the FDA asked the Company to provide a significant amount of additional information and follow-up from the recently completed adult study prior to further considering initiation of studies in children. At this time, ID Biomedical is not able to precisely predict how long it may take to generate this data and to what extent additional testing and follow up in adults may be required before obtaining approval to conduct studies in children. Based on a preliminary assessment of the nature and the amount of information requested by the FDA, the Company does not currently expect to begin testing the vaccine in children in the U.S. prior to 2007. The Company expects additional dialogue with the FDA regarding the requirements for continuing development of the vaccine candidate.
