Effective and secure transport arrangements should be in place for moving vaccines keeping the correct temperatures. The process can be defined in 5 steps:
- Assessing the shipment conditions.
- Deciding the suitable means for vaccine transportation.
- Preparing the shipment.
- Reception and Cold chain verification.
When opening new distribution channels or recurrent cold chain breaks are experienced in current distribution, qualifying transport routes is recommended. The process typically involves monitoring worst-case routes in order to ensure that the personnel and the chosen equipment and packaging arrangements are able to maintain acceptable transport temperatures even in such cases. Guidance on how to carry out a study of this kind is given in the WHO document Study protocol for temperature monitoring in the vaccine cold chain.
