This report describes and analyses the Global Polio Eradication Initiative (GPEI), a Global Public-Private Initiative (GPPIs) for health...The report focuses on the role of private sector partners in the operations and governance of the GPEI. It does not evaluate outcomes or effectiveness in much detail, nor does it provide an analysis of each company’s approach to GPPIs for healthcare in general. These issues are addressed in separate reports, including three reports on individual companies (Aventis, GlaxoSmithKline, Merck & Co) that relate their involvement with GPPIs to the core-business of the companies and to broader company strategies and policies for corporate social responsibility.
