ABSTRACT
The remainder of the industry’s revenue is attributable to two groups of suppliers: niche players in industrial countries and emerging country suppliers. A small number of primarily domestic suppliers in Europe, North America, and Japan play a minor role in serving small niche markets, for example, for biodefense or travel products. Emerging country suppliers are having a significant impact, serving their domestic markets and other low-and middle-income countries. Eight emerging country suppliers are currently World Health Organization (WHO)- prequalified to supply vaccines to United Nations (UN) agencies and the GAVI Alliance with several more actively seeking WHO prequalification (8).
