Vaccine Vial Monitor

The document describes a Vaccine Vial Monitor (VVM) that is used to monitor vaccines. The VVM contains an inner square and outer circle, where the square starts lighter than the circle and darkens over time and exposure to heat. Once the square matches or darkens past the outer circle, it has reached the discard point due to cumulative heat exposure and should no longer be used.
