The evolution of the VVM has been a long one, starting more than 40 years ago. This advancement has now been chronicled in The Book of VVM: Yesterday-today-and-tomorrow, by Dr. Umit Kartoglu, a former scientist for WHO.

The purpose of this study is to test the utilization of VVMs by the health personnel in the field and to monitor the change in vaccine wastage rates with the introduction of VVMs and open vial policy, as recommended by WHO.

This study was conducted to test under field conditions a methodology for evaluating the capacity of VVMs to (i) reduce vaccine wastage and (ii) monitor the status of the cold chain at the point of OPV use.
