Type of VVM assigned to vaccines

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...

Remote Temperature Monitoring Devices (RTMDs) User Survey

WHO PQS is conducting a survey to learn from users of Remote Temperature Monitoring Devices (RTMDs) and inform the future of vaccine cold chain monitoring. Have you ever… Received a text, email or notifications from an RTMD? Interacted with RTMD hardware in the field, including responding to alarms? Setup RTMD hardware and/or software? Interacted with an online RTMD web portal? Conducted repairs or service on RTMDs? If so, we want YOU to help inform the future of RTMD...

Finding the Perfect Temperature for Vaccines

Finding the Perfect Temperature: Protecting Lifesaving Vaccines in Remote Areas
Immunization is one of the most successful and cost-effective public health interventions in history, saving 2-3 million lives every year. In Tanzania, JSI is installing remote temperature monitoring devices to strengthen the immunization cold chain and ensure that vaccines make it to the last mile. 

DIGITALLY MIMICKING THE ANALOGUE FUNCTION OF A VVM

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 how the temperature history of the vaccine would affect its life, how would they do it? This is essentially the same problem faced when trying to interpret the data obtained from a refrigerator or va...

Temperature monitoring devices and Thermostat for vaccine refrigeration system

Dear Technet members, I would like to share my thoughts on the temperature monitoring devices and thermostal for vaccine refrigeration system. In the early days of EPI, temperature of the refrigerator was measured and displayed by a simple analogue thermometer which was either a bi-metal or stem type alcohol thermometer.  Twice daily the health worker records these temperature on the temperature monitoring sheet and posted on the door of the fridge.  Filled temperature records...

What is the recommended alarm temperature for vaccine storage

 I am setting up an alarm to indicate to high a temperature in a vaccine refrigerator.  I would appreciate it if someone could tell me the reccomended temperature and the time that  temperature must be maintained to set off the alarm?   My second question is if you what that time and temperature are based on?   Larry Schlussler       Sun Frost    ...

Cartographie de la température de Chambres froides au Niger

Bonjour Le Niger a entrepris en 2016 avec l'aide de ses partenaires la cartographie de la température dans ses Chambres froides. Nous avons beaucoup appris de cette expérience notamment sur : - La cartographie de toutes les chambres froides qu'elles soient anciennes ou nouvelles - Le réglage de la consigne d'arrêt des unités de réfrigeration - La fiabilité du Kit Berlinger (SmartView) Nous proposons les recommandations suivantes à d'autres pays intéress...

Introduction of the new temperature monitoring website

The WHO UNICEF immunization Supply Chain Hub (iSC Hub)has released a new temperature monitoring website hosted on TechNet-21.
A stringent system for temperature surveillance is essential to maintain the quality of the vaccines in an effective Supply Chain. By preventing vaccine exposure to freezing or hot temperatures in the cold chain, a functioning temperature monitoring system helps ensuring vaccine potency, avoiding both wasting vaccine investments (notably through reducing cl...

Evaluating Vaccine Temperature Monitoring Systems via Fuzzy Analytic Hierarchy Process

Interesting study from Turkey aimed at providing an approach to determine the best temperature monitoring system for vaccine storage in a warehouse.
AbstractCold chain management is a specific part of supply chain management. Cold chain managementdeal with products that should be transported and stored in certain conditions. Monitoring thetemperature in cold chain is one of the most critical and important factors. Effective temperaturemonitoring systems are a must have for a succe...

Temperature data logger training August 2016

Following the success of the first training session in December, 2015 on the use of the MULTiLOG2 Remonsys Ltd is planning to run a second training session in August this year.
Purpose and Objectives of the Course
The objective of this course is to equip delegates with the ability to install, configure and to operate the MULTiLOG2 system, to enable them to train others to understand the technology and how they can use it to make the best use of the recorded information to pro...

VVM colour change as a continuous progression

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 indicator label attached to the vaccine container (vial, ampoule or dropper) by the vaccine manufacturer. As the container moves through the supply chain, the VVM records its cumulat...

Remote Temperature Monitoring Data for Cold Chain Maintenance

Dear TechNet Colleagues,   I would like to share with you a report on our latest cold chain maintenance investigation in Mozambique: "Why Fridges Fail Part 2: RTM Data for Maintenance". We are beginning to document how remote temperature monitoring data and dashboards can be used by maintenance technicians to significantly improve cold chain performance. This assessment follows up on the randomized control trial conducted in 2014-2015 with Village Reach, PATH, ...

Last Opportunity to be heard - closing June 1 - Survey on Immunisation Supply Chain Dashboard Guidance

Dear colleagues: The Alliance Data for Management (D4M) working group is developing a guidance package on immunisation supply chain dashboards that includes a menu of primary supply chain performance indicators for countries to select from that meet their needs. The indicators and dashboards are intended for managers at multiple levels of the immunization supply chain and provide visualisation examples and suggested corrective actions for each indicator. This guidance will be endorsed by the ...

INFORMATION NOTE: Vaccine vial monitor (VVM) assignments for different WHO-prequalified vaccines

WHO and UNICEF have jointly prepared an information bulletin which addresses varied implications of different types of vaccine vial monitors (VVMs), notably VVM category type 7 (VVM7) and VVM category type 14 (VVM14), on vaccines such as the Inactivated Polio Vaccine (IPV) and the fully-liquid Diphtheria-Tetanus- whole cell Pertussis-Hepatitis B-Haemophilus influenzae type b (DTP-HepB-Hib, commonly referred to as pentavalent). The note is directed to countries that are currently supplied by U...

China considers VVMs

China considers VVMs by Qiyou Xiao, China National Biotec Group; Shuyan Zuo, WHO China; and Jack Zhang, PATH China In June, the first national seminar and information session about the necessity and feasibility of using vaccine vial monitors (VVMs) on domestically produced vaccines used in China was hosted by the Sinopharm Group. While the purpose of the meeting was exploratory, Sinopharm representatives indicated a two-fold interest in VVMs that has been growing over the past four years: (1) ...
