Work out cold chain storage capacity instantly with clear inputs, formula shown and shareable results.
Compares the packed volume of the doses to be stored with the usable share of a refrigerator's net volume, since airflow and stacking rules prevent full loading.
Cold chain capacity
Required litres = doses x packed volume per dose (cm3) / 1000; usable litres = net volume x usable share
WHO guidance requires air gaps for circulation and keeps vaccines away from walls and the freezer compartment.
The volume a dose occupies including its secondary packaging, published in WHO vaccine volume tables.
