GlaxoSmithKline plc (NYSE:GSK) announced the completion of the acquisition of ID Biomedical. This follows regulatory clearances of the transaction and adoption of the acquisition agreement by ID Biomedical's shareholders (which occurred on the 16th of November). ID Biomedical becomes a wholly-owned subsidiary of GSK.

?This is a major step toward fulfilling our mission of becoming a leading global influenza vaccine manufacturer,? said Jean-Pierre Garnier, Chief Executive Officer of GSK. ID Biomedical provides GSK with a significant increase in flu vaccine manufacturing capacity, which will improve GSK's ability to address both seasonal and pandemic influenza threats. The combined seasonal flu vaccine production capacity of the newly acquired Canadian facilities and of GSK\'s Dresdenplant, Germany, is expected to reach around 150 million doses per year before the end of this decade.?We are actively working with governments and health authorities around the globe to support their plans for pandemic flu readiness and we are committed to bring the capabilities of our flu vaccine production facilities to the global preparation effort,? continued Garnier.

The acquisition of ID Biomedical reinforces GSK's commitment to the North American vaccine market. This transaction follows recent strategic initiatives to expand its vaccine research and production network in North America, including the acquisition of Corixa Corporation and the purchase of the Marietta, PAvaccine site.

?With this acquisition, GSK continues to move forward to support the delivery of GSK's broad pipeline of novel vaccines in North America,? said Jean St?phenne, President of GSK Biologicals, the vaccine division of GSK. ?We are very pleased to expand GSK\'s vaccines capabilities in Canada. We have every confidence that the excellent relationships built up by both organizations with the Canadian public health authorities will continue,? he added.

GSK is dedicated to the improvement of existing flu vaccines and to the development of new influenza vaccination approaches. This includes the use of its expertise in novel vaccine adjuvant technology to develop an improved flu vaccine for the elderly and to produce more effective pandemic flu vaccines. In addition to providing GSK with increased production capacity for next generation influenza vaccines, ID Biomedical brings an intranasal flu vaccine candidate that could help GSK to address the public health need for new delivery systems.
