The story of a time and temperature indicator that has dramatically changed the course of vaccine
management practices as well as shaped the future of the cold chain.


Here is a fun game for you. The challenge is to put VVMs in order from light to dark (from left to right). Just drag the VVMs to the below empty box, putting them in order from left to right. When playing the VVM color game, you need to be aware that anytime you make a mistake in order, you will lose everything you have correctly done before that mistake. This will make you start again. You have to put everything correctly without any mistake.

There is a timer on the page to help you track your time in completing the matching cards. This timer is only for your records.
