The Vaccine Innovation Prioritisation Strategy (VIPS) is a collaboration between the Gavi Secretariat, World Health Organization (WHO), Bill & Melinda Gates Foundation (BMGF), United Nations Children’s Fund (UNICEF) and PATH to evaluate and prioritize vaccine product innovations for low- and l...

Please join us for a webinar on vaccine vial monitor (VVM)-based vaccine management, on the occasion of publishing of “The Book of VVM: Yesterday-today-and-tomorrow” by Umit Kartoglu. The webinar will take place on Tuesday, January 21st at 4pm CET. During the webinar, the presenters will discuss the...

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...

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...

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 ...

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 regard...

Last week marked the second occasion that a Controlled Temperature Chain (CTC) has been officially used with a vaccine licensed, pre-qualified, and labelled accordingly. Mauritania has just completed a Meningitis A immunization campaign (scheduled from October 14th to the 23rd) using the Meningococ...

The results of a study conducted by Epicentre /Médecins Sans Frontières (MSF) assessing the immunogenicity and safety of a tetanus toxoid vaccine have been recently published in Vaccine.[sup]1 [/sup] The study was conducted in collaboration with the Project Optimize, the Belgian Institute of Public...

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...

This note has been cross-posted from the GAVI CSO forum with many thanks! Dear colleagues, This week on occasion of the World Immunization Week, Médecins Sans Frontières/Doctors Without Borders (MSF) has released a call for greater attention to the need for heat-stable vaccines to facilitate acc...

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 Dan Brigden, PATH In November 2012, the first immunization campaign to use a controlled temperature chain (CTC) took place in Banikoara in northern Benin. This photo set contains photographs taken during the campaign, where over 155,000 people were vaccinated using the CTC approach. Access ...

http://www.timesche nnai.com/ index.php? mod=article&cat=General&article=47839 Now vaccines can be stored at room temperature 02.18.2010 (GMT+5.5) London: For the first time scientists at Oxford University have found a way of keeping vaccines stable without refrigeration, even at tropica...

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...
