Caution For Usage
Incompatibilities: In the absence of compatibility studies, the vaccine must not be mixed with other medicinal products.
Vaccine Vial Monitor: The Vaccine Vial Monitor (VVM) is part of the label used for all Healive batches supplied by Sinovac. The colour dot that appears on the label of the vial is a VVM. This is a time-temperature sensitive dot that provides an indication of the cumulative heat to which the vial has  been exposed. It warns the end user when exposure to heat is likely to have degraded  the vaccine beyond an acceptable level.
The interpretation of the VVM is simple. Focus on the central square. Its colour will change progressively. As long as the colour of this is lighter than the colour of the ring, then the vaccine can be used. As soon as the colour of the central square is the same colour as the ring of a darker colour than the ring, then the vial should be discarded.
It is absolutely critical to ensure that the storage conditions specified above (in particular the cold chain) are complied with.
Sinovac will assume no liability in the event Healive has not been stored in compliance with the storarge instructions. Furthermore, Sinovac assumes no responsibility in case a VVM is defective for any reason.
