Vaccine vial monitors: Transforming the way we can deliver vaccines

WHO/Umit Kartoglu

Tetanus toxoid vaccine labels with VVM are being attached to vials at a manufacturing facility in Bandung, Indonesia. Being available on the vial, the indicator can be checked at any time to determine whether or not the vaccine has been damaged in heat. No other temperature monitoring device is available at all time from vaccine production to its use.
