Vaccine manufacturers Five Pharma firms (US/Eur)
• Profitable companies • Charge high prices for new vaccines • Concentrate on low-volume rich world markets
Emerging suppliers
• Traditionally sell older, less complex vaccines • High-volume and low-margin markets • Interest in developing more complex (higher
margin) vaccines

Meningitis in Sub-Saharan Africa
• Over 90 percent of global meningococcal disease occurs in the African meningitis belt
• Attacks children, young adults and infants
• One third of meningitis cases die (10%) or are disabled (23%)
• One strain (Group A Nm) accounts for estimated 80% of all meningococcal cases.
• Epidemics occur every year
• Poorest countries in the world
• New vaccine cost is critical to sustainability

•The “intensive care unit” of Africa
•Individuals are treated where they fall
•Very few hospitals in this region; makeshift clinics are established when needs arise

(< $US 0.50 per dose) vaccine designed specifically for Africa to protect against
meningococcal meningitis
