Study protocol for temperature monitoring in the vaccine cold chain


This Protocol is designed to: 1) document temperature exposures throughout the vaccine cold chain with a special emphasis on the level of freezing; and 2) identify specific problem areas where corrective actions are warranted. In this Protocol, temperatures are monitored continuously as vaccine shipments travel through the cold chain, from primary stores, to intermediate stores, to health centres and, finally, to the outreach delivery site/s. This Protocol can be tailored to meet the individual resources of any programme: either a simple, low-cost study can be conducted – without sophisticated monitoring tools – or a more comprehensive approach can be taken to provide more details.
