Immunization outreach services depend on a protective, affordable and efficient supply chain to benefit rather than obstruct outreach operations. Four potential cold-chain solutions are on offer but each has barriers to be negotiated or removed. The options are:
- Frozen water packs BUT we should switch to freeze-free vaccine carriers to avoid the risk of freezing:
- Vaccines certified for use in a ‘Controlled Temperature Chain’:
- PCM-filled packs used in all existing carriers and boxes prevent freezing BUT pending resolution of cost and other issues by WHO.
So, which of the 3 solutions interests you most? Do you know of others? I await your views and look forward to a lively discussion!
