In addition, VVM is a tool for deciding which multi-dose vials can be kept and used for future immunization sessions.

It features animated tutorials and integrated knowledge assessments authored by subject matter experts.This course includes one module organized in six sections:For questions or feedback on this programme, please contact Ousmane Tamba Dia, Senior Immunization Specialist at.This activity or course is open to self-enrolment.Comments and questions can be addressed to.UNICEF promotes the rights and wellbeing of every child in 190 countries and territories, with a special focus on reaching those in greatest need.Developed jointly by UNICEF and WHO, the Immunization eLearning Initiative provides all immunization staff with access to training in areas deemed vital to the advancement of the Global Vaccine Action Plan and its vision that everyone live a life free from vaccine preventable disease.Today, millions of vaccine vials are distributed, stored and administered around the world along the cold chain. A vaccine vial monitor (VVM) is a label containing a heat- sensitive material which is placed on a vaccine vial to register cumulative heat exposure over time. Five senses; 10 year anniversary; Interviews on VVM history; VVM history and milestones pdf, 49kb; What is VVM and how does it work? As low- and lower-middle-income countries transition beyond support from the Global Alliance for Vaccines and Immunization (Gavi), they will assume full responsibility for vaccine financing and procurement. Now, they can rely on vaccine vial monitors (or VVMs) to determine whether a vaccine is safe to use. VVMs also help health care workers decide which vaccine to use first when vials have been exposed to different temperatures. The vaccine vial monitor (VVM) registers cumulative heat exposure on vaccines over time. VVMs, vaccine vial monitors, are small stickers that adhere to vaccine vials and change color as the vaccine is exposed to heat, letting health workers know whether the vaccine can be safely used for immunization. watch, DT and TT shipping indicator World Health Organization ( World Health OrganizationWorld Health Organization , 1999 )
The combined effects of time and temperature cause the inner square of the VVM to darken, gradually and irreversibly. In this course, you’ll learn about the impact that extreme temperatures can have on vaccines and how to interpret vaccine vial monitors (VVMs) to identify vaccines that can and cannot be used. Additionally, you will learn how to sort vaccines based on their type and VVM category and use VVMs to apply the Multi-Dose Vial Policy.At the end of this course, you will be able to:This course is intended for health workers and staff responsible for in-country vaccine management or outreach operations. VVMs also help health care workers decide which vaccine to use first when vials have been exposed to different temperatures.

If the monitor is exposed to heat it changes color with time and with increasing speed in hotter conditions. INTRODUCTION: The vaccine vial monitor (VVM) registers cumulative heat exposure on vaccines over time. VVMs contain a heat-sensitive material that registers the cumulative heat exposure of the vial over time.
In addition, VVM is a tool for deciding which multi-dose vials can be kept and used for future immunization sessions. It is
In the past, health workers were trained to discard all vaccines after a suspected break in the cold chain, often wasting large amounts of usable vaccine. How do VVMs work? Temperature monitors for vaccines and the cold chain : cold-chain monitor, vaccine vial monitor, Freeze watch, Stop!
It also intended for in-country staff responsible for advising or supervising health workers who work with vaccines, as well as consultants and partners working in support of immunization.This course consists of one module with a total duration of approximately 20 minutes.This course is comprised of one self-paced e-learning module.
