How to verify a passive carrier suits a vaccine

Match model, product instructions, pack layout and route evidence; catalogue duration is not qualification.

Short answer

Start with the vaccine’s current storage information and programme or institutional instructions. Match carrier model, pack conditioning and layout to manufacturer IFU; review qualification evidence covering sensor positions, real load and route conditions. If an excursion occurs, segregate the product and preserve records; obtain written use or disposal direction from the product owner and authorised quality lead.

A passive carrier’s suitability is not established by model name or catalogue duration alone. Look for documented fit among vaccine, pack layout and field route.

Match documents and test

File the product’s transport/storage information and programme instructions. Compare carrier model, pack conditioning, barrier, loading diagram and logger position with the manufacturer’s instructions for use.

Check whether the qualification report’s load, ambient profile and sensor positions represent your route. Record field differences, waits, openings and receipt measurement; do not present a catalogue claim as your own evidence.

If report scope is insufficient, do not declare the carrier suitable for dispatch; request further assessment. For an excursion, segregate the load, preserve raw data and obtain written direction from the product owner.
