UNICEF needed a vaccine carrier for last-mile delivery in sub-Saharan Africa. 5,000 carriers for routine immunization (EPI) and 1,000 for COVID-19 mRNA vaccines (which require -20°C storage). Carriers must survive 40°C ambient, 30-day shipping via road/boat/foot, and be carried by health workers (often on motorbike or bicycle). Previous suppliers had 18% failure rate within 6 months.
KeXinMaterials' WHO PQS E001-prequalified vaccine carrier (KX-VC-50): 50L volume, 48-hour cold life at 2-8°C with WHO PQS test conditions, 24-hour at -20°C for mRNA. Phase-change material (PCM) cool packs. EPP foam insulation 50mm thick. Steel-belt reinforced PP outer shell. Serial-numbered for tracking. Lockable for security. 6,000 carriers produced over 24 months.
After 24 months in 23 African countries: 92% survival rate (vs 82% industry average, 78% previous supplier). Cold life: 95% met 48h spec. UNICEF expanded order by 40% for 2026. WHO referenced the KX-VC-50 in their 2025 vaccine carrier procurement guidelines.
