Dear experts
I like to share some constraints about of ULT equipments vs ILR.
1. Cost: USD 28.000 in Colombia to ULT vs USD 2.500 in Colombia to ILR, prices with taxes, that means a ratio of 11,2:1
2. Weight: 271 Kg. to ULT vs 100 Kg. to ILR, 2,71:1
3. Energy consumption, stable running: 17,5 KWh/24h to ULT vs 0.62 KWh/24h to ILR. 28,2:1.
4. Maintenance service: to ULT lack of expert technicians vs enough and easier maintenance to ILR.
5. The high quality of the energy for ULT is crucial and these does not ever is achieved in all the countries and rural zones.
Furthermore, the time required to produce ULT equipments is longer than ILR and the time is very limited. No one vaccination campaign has been carried out in less than six months. Look at seasonal influenza and measles with very little population compared to this COVID 19 goal.
CO2 to put inside of cold boxes and vaccine carriers is very expensive and its production is very limited or nule. Focusing all the effort on this frozen vaccine against COVID 19 reduces the coverage of the rest of the vaccination scheme.
The longer the vaccine takes to become available, the more people will not get vaccinated.
Very interesting discussion and some important points made.
Over the last year, WHO and UNICEF offices at all levels have been communicating intensively with member states about cold chain and ultra-cold chain (UCC) equipment deployment to support possible COVID-19 vaccine introduction. While the logistical challenges of doing so in LMIC settings are clear, experience with deploying the Ebola vaccine has proved that it is not impossible. WHO and UNICEF continue to be to provide countries with the necessary tools and guidance to make the correct decisions to support their immunization needs and goals. Related to this, members be interested in the following ISC resources and guidance, some recently shared on TechNet-21:
COVID-19 Vaccination, Country Readiness and Delivery: Supply and Logistics Guidance (working copy)
"The COVAX Supply and Logistics workstream, led by UNICEF, Gavi and WHO, have released a working copy of the COVID-19 Vaccination, Country Readiness & Delivery: Supply and Logistics Guidance. Countries might find this Guide useful when developing and strengthening their supply chain strategies to receive, store, distribute and manage the COVID-19 vaccines and their ancillary products, in line with their national deployment and vaccination plan (NDVP). The document also provides links to the different tools and resources to aid countries in performing assessment, planning and capacity-building activities."

COVID-19 Vaccine Introduction Readiness Assessment Tool (VIRAT/VRAF 2.0) - Version 3 December 2020
This Readiness Assessment tool is a national level tool. Data inputs should be entered into the worksheet 'National Readiness'. Suggestions for timing and intervals to implement activities and assess progress are provided in the timeline. Pre-planning activities should be initiated as early as Sept 2020 (earliest time interval provided) as COVID-19 vaccines may be available for introduction by early 2021. The tool will be updated as soon as more certainty about global vaccine supply availability becomes available. DRAFT DOCUMENT, PENDING PUBLICATION ON THE WHO WEBSITE.

Dear Isaac
Could you inform us about the advance of the specifications and testing protocols to ensure the performance, quality and safety of ultra-low temperature (ULT).
Thanks.
