Strategic Positioning

  • Manufacturing: AIM’s Changchun facility (capacity 80 million doses/year) can produce PCV20 with minimal retrofit; WHO Pre‑qualification targeted by 2028 for UN procurement
  • Clinical Pathway: Phase I/II bridging study vs. Prevenar 20 planned Q2 2026; Phase III superiority trial to demonstrate broader serotype coverage vs. PCV13
  • Commercialization: Existing 2,000‑hospital distribution network for PCV13 can be leveraged; private market launch expected 2028, NRDL negotiation in 2029
  • Global Ambitions: Ex‑China licensing discussions underway with GSK and Serum Institute for low‑middle income markets
