PATH is pleased to present “Building Next Generation Immunization Supply Chains” a special edition of Vaccine journal which brings together evidence from global experts in 31 articles representing decades of work by country governments, implementing partners, and donors to improve immunization suppl...

Dear all, I would like to share with you a position statement from the Immunization Practices Advisory Committee (IPAC) on the Controlled Temperature Chain (CTC) and the use of vaccines out of cold chain (OCC). This statement has been prepared by the CTC working group, which has been established un...

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 s...

Hi all, I am quite new to the CTC adventure. After reading the second draft of the WHO CTC guideline, now ECTC (I also wen through the first version and the discussion in Langen and Ottawa), several questions came to my mind, and I would be extremely grateful if some of the forum members can help ...

I’m delighted to announce the online release of WHO’s new 3-part film on the Controlled Temperature Chain (CTC) produced by IVB/EPI in both English and French. This 3-episode film on CTC serves as an advocacy tool in order to promote the approach among varied stakeholders. The first episode explain...

How about a Buffered Temperature Chain (BTC)? Vaccines which are highly thermally stable can be distributed in the Controlled Temperature Chain (CTC). To be incorporated into the CTC the vaccines must be stable enough to be stored for 3 days at 40 deg C. There are very few vaccines which are this...

A new infographic that explains "What is a controlled temperature chain (CTC)?" is available on the WHO website: http://www.who.int/immunization/programmes_systems/supply_chain/resources/WHO_CTC_Infographic.pdf...

In recognition that an increasing number of vaccines are able to tolerate temperatures well above those officially stated on their labels, the World Health Organization (WHO) has been supporting efforts to assess and take advantage of the true heat stability of vaccines. Upstream work in this rega...

A couple of months ago, Médecins Sans Frontières (MSF) produced a package of materials in support of their call for wider use of existing vaccines in the “controlled temperature chain” or CTC. An issue brief, Vaccinating Children Beyond the Cold Chain, is available in English and French. It is a...

The need to keep vaccines in a 2°C to 8°C cold chain is a constraining factor for many immunization campaigns due to limited storage capacity and/or limited ice pack freezing capacity; supplementary immunization activities planned across sub-Saharan Africa to introduce MenAfriVac™ are a good example...

by Michel Zaffran, WHO; Julie Milstien, consultant; and Modibo Dicko, WHO It has long been known that certain vaccines are stable for long periods of time at temperatures outside the standard cold chain protocol of 2[sup]o[/sup] to 8[sup]o[/sup]C. However, until recently, there have been few rea...

Today, most vaccines are licensed for storage between 2-8°C, regardless of their true stability. While there are some vaccines that do need to be kept at this specific temperature range, studies have shown that most vaccines are able to withstand higher temperature ranges for a specific period of ti...
