Vaccine Vial monitor
An important improvement in PPI during 1998 has been the use of
vaccine vial monitor.
Colour monitors or labels are put on vaccine bottles.
Each label has a circle of deep blue colour.
Inside it is a white square which changes colour and gradually
becomes blue, if vaccine bottle is exposed to higher temprature.
When the colour of the white square becomes blue like that of
surrounding circle, the vaccine should be considered ineffective.
Thereby, the health worker can easily ascertain that the vaccine
being given is effective or not.
