The story of a time and temperature indicator (vaccine vial monitor) that has dramatically changed the course of vaccine management practices as well as shaped the future of cold chain, THE BOOK OF VVM: YESTERDAY-TODAY-and-TOMORROW is now available for free download in ePUB3 and PDF formats. http:/...

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...

After reading Umit's book my interest in what I call the "buffered Cold Chain" BCC, was renewed.In his book I found the history and the description of the obstacles which were overcome very interesting. By BCC I mean a cold chain which will maintain temperatures between 20 degC and 25 degC . These ...

Dear colleagues, I am working on a new book project on VVM. I would like to include examples of the following and shall be grateful if you could kindly contact me. Your help is much appreciated! If you have any of the following, besides sending the material, I'd appreciate it if you could kindly ...

Dear all,  Can any one explain how the decision is made as to which type of VVM is assigned to different vaccines, with examples? Are same vaccines manufactured by different manufactures assigned different type of VVM? Thanks,  Chandralal...

Imagine that VVM’s do not exist. As an alternative a tiny electronic device could be developed which would record the temperature history of the vaccine vial. The device would be attached to the vial and graphically display the temperature history of the vaccine. If a health worker wanted to know ho...

Most of the countries now have improved immunization coverages and reach more children with vaccination, but we still need to monitor the potency of vaccines that are given on top of the high coverages we have achieved in many countries. One of the biggest challenges when we talk about vaccine pot...

Dear viewers  All of us are witnessing rapid multidimensional growth of routine immunization in the current decade. Keeping pace with the rapidly expanding / frequently changing schedule itself is a challenge faced by the service providers, more so in the private sector. Pilot study revealed dange...

Dear Colleagues, I trust this post finds you all very well! I would be grateful if you could please provide (based on your experiences), the possible sources (misuse, VVM, expiry, breakage, etc.) and rate of occurrence of close vial vaccine wastage at the lowest distribution and service delivery l...

Vaccines can tolerate temperatures above 8 deg C however temperatures below 0 deg C will freeze a vaccine and it will lose it’s efficacy. At temperatures above 8 deg C the life of a vaccine will be lowered but the exposure will not be catastrophic. For the most sensitive vaccine, VVM II, the life of...

WHO has just released a new infographic that summarises how health workers can use vaccine vial monitors (VVMs) to decide whether or not to use a vaccine vial. Most notably, it presents VVM colour change as a continuous progression, rather than as four distinct stages. A VVM is a chemical indicat...

Dear viewers In one of the Training of Trainers programme in 1990’s at Chennai, a resource person told that ‘ASA’ – Attention, Suspicion and Authority are the 3 important elements of any good surveillance. Through high sensitivity, observational capacity, timely reporting often rare syndromes were...

Below are some examples of how an MKT thermometer could be used to to simpllfy temperature data analysis for the cold chain. If the temperature in a refrigerator is 4 deg C for 20 hours then increases to 15 deg C for 4 hours, how will the vaccine life be affected? - If this is a one day occurrence...

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...

Can any one help me that is there any VVM checking policy/guideline available with WHO in between receiving and dispatching of vaccines....
