Hi colleagues, I am looking to copile a photo album of cold chain equipment in use from the launch of EPI in 1974 until the the birth of WHO PQS in 2007. If you have any good examples of early vaccine refrigerators and freezers (or domestics), cold boxes, vaccine carriers, and temperature monitoring devices, please share! And if you could give some explanatory information (year, country, model, etc.) that would be even better :-) Many thanks.
PS If you are interested, the following two articles by John Lloyd give a fascinating insight into the early days in the evolution of the vaccine supply chain.
