As various COVID-19 vaccines are in the making, there is a lot we can do to prepare for their handling including necessary cold chain and ultra-cold chain solutions. Here is a fact sheet with reminders and recommendations.
General issues with temperature control:
- Control temperature range,
- Control exposure: deviation from range, time period of exposure
Typical issues with vaccines:
vaccine comes with their own temperature control requirements
- e.g. Vaccines with live components: cannot freeze (kills the live component)
- Very special: Ultra-cold chain (minus 70-80 degrees C)ones, e.g. ebola vaccine
- NB! Pfizer’s potential vaccine needs an ultra-cold chain, but other COVID-19 vaccines in the making need different temperature ranges.
Typical issues with temperature control supply chains:
points aka where temperature control usually breaks down:
- Materials handling (offloading, cross-docking, intermodal transportation, customs clearance)
- At the user’s end: health care centres without stable electricity, patients (if they can buy a vaccine themselves)
- Needs dedicated handling spaces (warehouses, cross-docking spaces, special units at customs) and equipment that works with the required temperatures
- Needs special transportation, e.g. reefer containers (the ultra-cold chain a combination of special packaging + special reefer containers). Some of containers need electric connection during transport and storage.
- Vaccines need special medical clearance for materials handling! (i.e. staff that has the required certifications in warehouses, transportation etc.)
- Don’t forget about the kits! (e.g. syringes, gloves, test swabs, lab equipment etc.) to go with the items. Note, they may need different temperatures than the vaccine itself!
sizes matter in light of how long you can open a package
- Peri-urban/rural distribution
- Avoiding too many people coming to a vaccination centre – disease control!
Administering vaccination programmes
- Ideally not overloading the same health care centres
- Segregation of patients (sick) from those to be vaccinated
- Train (more) people to administer vaccines – separate capacity from testing stations will be needed
Industry initiatives for handling temperature control:
- GDP – good distribution practice, esp. in pharma
- CEIV – IATA’s pharma distribution practices for freight forwarders (not just airlines)
Current initiatives for potential COVID-19 vaccines:
- UNICEF Covax: pre-procurement of items for the kits (e.g. syringes), stocking up
- Logistics service providers developing more temperature control warehouses around the world
- Pfizer developing their own cold chain packages
Recommendations, aka what different organisations and countries can do to prepare for it now:
cold chain, and ultra-cold chain capacity in warehouses and transportation
- Actual spaces and equipment (warehouses, refrigerated containers, vans, trucks, railway carts)
- Cold chain training across whole supply chain (warehouse operators, drivers, medics)
- Certifications (GDP, CEIV, medical materials handling requirements)
- Production changeover in transportation: re-equipping existent aircrafts, containers, vehicles for the ultra-cold chain
- Production changeover in warehousing, e.g. setting up freezer farms near airports and other hubs
- Some solutions exist already in the food and pharmaceutical sectors
- Be part of
vaccine procurement initiatives – e.g. the EU has one for all EU countries
together, and has signed agreements with several potential providers
- Joint procurement may give better purchasing power, but this is a sole supplier situation, after all
- Prepare tenders and advanced purchase agreements either individual or jointly with other organizations
- Remember equity in health
- Start off
getting the rest of the kit together! Vaccine distribution will require all the
rest of it, from materials to set up vaccination centres, to actual testing and
- Potential reuse/adaptation from the Ebola vaccination campaign in challenging contexts
- Benchmark/best practice from INGOS continuously involved in EVD (e.g. MSF, IFRC, ICRC, UNICEF)
- Develop containers for smaller quantities (the current Pfizer solution may not be applicable for smaller populations)
- Check existing inter-agency health kits for vaccination kits. Add also dry ice for further cooling.
procuring logistics services and work with logistics service providers to
ensure they have the right equipment and capabilities
- Set up tracking and tracing through the supply chain, to assure correct procedures are followed. Special cold chain tracking devices exist on the market already.
- Design security around the chain, to control and protect the flow.
vaccine distribution plans
- Identify places (health care centres, schools, voting stations or other, depending on the current burden in existing health care centres) with good coverage of the population. Know your coverage!
- Identify groups that need to be vaccinated as first (such as those who will administer vaccines later), and define criteria to select locations that will be vaccinates as first (number of cases, density of population)
- Contact and make agreements with transportation and logistics service providers for the last mile distribution
- Collaborate with other organizations or countries for the transportation of the vaccine
- Identify which organisations or sectors within the country could support a vaccination programme, in case if medical system is overwhelmed with COVID19 cases, and identify their needs for training. (Possible organisations include medical humanitarian organisations, the Red Cross movement, in some cases even defence forces.)
- Train people in advance, both in medical logistics, vaccine handling, and for managing vaccination centres
- Set up communication channels, how people will be informed when and where vaccination will take place
- Set up tracking system to identify who already got the vaccine, this is critical when more than single doze is needed
- Assure that all labelling on packages, instructions and guidelines are in all required languages
- Identify and review relevant country laws and regulations, to assure that mass vaccination programme is in line with them
- Analyse risks and create response plans, in case of electricity supply cuts, accidents, missing resources
- Create waste (and re-use) plans for used boxes, gloves, needles and other equipment
- Before going life within the programme run simulation, and exercises to check if plan is realistic
There is a lot more with regards to ethical considerations, trust-building, and even the prioritisation of vaccine recipients etc. Thus, as a final note, please remember that this list focuses on cold chain, and ultra-cold chain capacities and capabilities. Let’s leave the rest to the epidemiologists.
