In May 2006, the WHO published a Global Pandemic Influenza Action Plan. A significant part of that plan involves the transfer of technology necessary to build production capacity in developing countries. The WHO influenza technology transfer initiative has been successful. Clearly the relatively small WHO investments made in these companies to develop their own influenza vaccine production facilities have had quite dramatic results. A few companies are already producing large amounts of influenza vaccine. Others will soon follow. Whether they are developing egg-based or planning non-egg based influenza vaccine production, all companies are optimistic that their efforts will come to fruition.
