They fail because technicians don't believe their actions will be supported.Imagine you have to travel 30 km to a facility where the refrigerator has failed. Before you can go, you need a transport allowance, and approval takes several layers of sign-off. The road is bad, so the trip takes three hou...

Dear Colleagues, We've developed a lightweight web tool for calculating the net storage capacity of an existing cold room from its installed shelving, and we'd value critique from this community before we take it further. The gap we're trying to fill The established tools — the WHO Vaccine Volume...

Dear Colleagues, We are pleased to share that the upgraded version of the Immunization Forecasting and Supply Planning Toolbox webpage has been released on TechNet: https://www.technet-21.org/en/immunization-forecasting-and-supply-planning-toolbox Originally launched by UNICEF in collaboration wit...

Pour renforcer la surveillance et la maintenance des équipements de la chaîne du froid, le ministère sénégalais de la Santé, avec le soutien de PATH, a développé le CCE/EPI Tracker, une solution numérique intégrée à DHIS2. Rejoignez ce webinaire pour découvrir comment l'outil permet la surveillance...

Keeping vaccines safe requires more than deploying cold chain equipment. It also requires reliable systems to monitor performance, track temperature data, manage maintenance activities, and support timely decision-making. Join us to learn how Senegal's Ministry of Health, with support from PATH, in...

Vaccines like BCG and Measles must be kept between + 2°C to +8°C. Is there any risk if these vaccines were placed on the bottom shelf of combo/combination refrigerator, where the temperature may drop below sub-zero? In the past these freeze dried vaccine were stored in minus temperature....

Countries across sub-Saharan Africa continue to make progress toward improving routine immunization (RI) coverage, yet significant operational challenges remain in delivering potent vaccines to underserved and hard-to-reach populations. Outreach immunization activities are routinely conducted in env...

How many single-dose IPV vials and 5-dose of measles vaccine vials can be stored in a net one litre space in a combo refrigerator?...

Dear all, I want to share with you the experience about packaging vaccines that require to be between -50ºC and -15ºC to maximize the shelf life given by the lab.We prepared a 40% solution of Mono Ethylene Glycol with water inside HDPE bottle (icepacks), freezing at -50ºC for 2 days at least, then ...

The Gavi 6.0 immunisation supply chain (iSC) strategy marks a shift toward more country-led, system-wide strengthening, focusing on the most critical bottlenecks and long-term sustainability. It promotes coordinated improvements across the full delivery system, from data and planning to workforce, i...

Join us for an introduction to the Gavi 6.0 Immunisation Supply Chain (iSC) Strategy and explore how it can be applied in practice to strengthen country planning and partner engagement. This session will unpack what is new in the Gavi 6.0 iSC Strategy, how it fits within the broader Gavi 6.0 and he...

Nine officials from Egypt’s Expanded Programme on Immunization (EPI) strengthened their technical skills in Cold Chain Equipment Management (CCEM) during a 10-day training at the EAC Regional Centre of Excellence for Vaccines, Immunization and Health Supply Chain Management in Kigali, Rwanda (3–15 M...

A new tool for collecting, analysing, and reporting temperature data has been released by WHO. This Microsoft Excel tool, which can be used as part of a temperature monitoring study, is available as a zip file on the WHO website, and comes with a set of user documentation.  www.who.int/publica...

The ‘Cold chain equipment and dry store temperature mapping tool’ is a tool for mapping temperatures in various types of cold chain equipment and dry stores and is available in official United Nations (UN) languages. Version 10.0 was released in January 2026 and includes various performance improvem...

Are you interested in how cutting-edge technology is solving real-world challenges with the vaccine cold chain? Join us for an exclusive deep dive into the Varo/Pogo-LT application - a game-changer for temperature data collection and vaccine safety. We’re exploring how this innovative tool is being...

Here is something we rarely say out loud in our sector. Every time we pull a pharmacist or a logistician out of their facility for a classroom training, the pharmacy or the supply chain behind them doesn't pause. The stockouts don't wait. The cold chain doesn't care about the workshop schedule. &n...

Hi, TechNet Friends. We are conducting a short research survey on vaccine cold chain reliability and would welcome your participation. The survey is part of a study applying a behavioral science framework to the operational practices that sustain immunization supply chains — an area where the exper...
