Supply reserved by Industrialized Countries Key Factors How will production capacity be used to produce H1N1 vaccines? – Utilization of current downtime – Utilization of seasonal SH and/ or 2010/11 NH production window What H1N1 vaccine orders have been negotiated? – Number of doses – Timing of vaccine delivery What other countries intend to purchase H1N1 vaccine? Available Supply 8| Extraordinary SAGE meeting | 7 July, 2009 What are the most vulnerable population groups who should priority have access to H1N1 vaccine? Countries are drawing against this capacity in different ways Population % of H1N1 Capacity1 893 M 90% (e.g., U.S., Canada, Europe, Japan, Australia) Mostly open system: Countries negotiate contracts for vaccine with major, industrialized country manufacturers – Facilities serve home countries and export to other markets Low / Middle Income with local supply Mostly closed system: Will procure vaccine mainly from within country – Limited or no plans by manufacturers to export 3,114 M 10% No current access to H1N1 vaccine 2,662 M N/A Segments High-income (e.g., China, Russia) Low / Middle Income without local supply Access Strategy 1 Refers to portion of capacity located within these countries.

Use of oil-in-water adjuvants will dramatically increase vaccine availability > important role of regulators and industrialized country governments in increasing overall production output and access for poor countries A better understanding of developing country H1N1 vaccine demand is needed Upcoming SH and NH seasonal vaccine production will severely diminish availability of H1N1 vaccine > strategies may be needed to decrease impact (review or epidemiology in Sept 2010)? 18 | Extraordinary SAGE meeting | 7 July, 2009
