WHO EUL: A Fast Lane for Cold Chain in Emergencies
The Emergency Use Listing (EUL) procedure traces back to WHO emergency use assessment mechanisms (applied during Ebola) and was significantly expanded and brought into global prominence during COVID-19. It provides a fast track for newly developed vaccines while raising the bar for cold chain systems.

Key strengths
- Rapid response: typical review period 4-8 weeks per WHO EUL procedure (Pfizer-BioNTech actual: 5 weeks during COVID-19)
- Tight coordination with COVAX, covering low-income countries
- Explicit cold chain requirements that elevated ultra-low temperature attention
Transferability to China
China’s emergency conditional approval mechanism can adopt EUL practices in transparency and documentation.
