Epidemiological Rationale & Public Health Impact

Competitive Landscape Analysis

Commercial Opportunity Assessment

• Addressable Population: Expansion adds ~120 million adolescents (ages 7-17) to existing ~90 million children (ages <7)

• Revenue Impact: Age expansion could increase annual revenue by ¥800 million-¥1.2 billion ($110-170 million) at 15-20% penetration
• Market Leadership: Solidifies CanSino’s position as dominant player in China’s meningococcal vaccine market

Strategic Implications

• Pipeline Validation: Demonstrates CanSino’s regulatory expertise in managing complex vaccine approvals and expansions
• Manufacturing Scale: Existing production capacity positioned to meet expanded demand without significant capital investment
• International Potential: Success in China’s large market strengthens foundation for potential global regulatory submissions
• Portfolio Diversification: Reduces reliance on COVID-19 vaccine revenue through established routine immunization product
• Investor Confidence: Consistent regulatory progress supports long-term growth narrative beyond pandemic-related products
