EAST HILLS, N.Y.--(BUSINESS WIRE)--Oct. 28, 2005--As avian flu concerns extend across the globe, governments and pharmaceutical manufacturers face potentially huge demand for vaccines. According to public health experts, current production capacity and response times would not suffice in the event of a pandemic. Viral vaccine development is governed by stringent regulatory controls and can take as long as eight to 12 years costing anywhere from $300 to $800 million USD. In a presentation at the 10th annual China International Pharmaceutical Industry Exhibition in Shanghai, Ian Sellick of Pall Corporation (NYSE: PLL), described how the use of disposable and scalable technologies to purify large molecule vectors, such as for flu vaccines, can help manufacturers streamline the process and overcome many of the unique challenges associated with vaccine development.
