All the (currently authorised and approved) vaccines against SARS-CoV-2 are required to be stored within specific temperature bands and if there is transgression outside of these bands there is a risk of physical corruption: this has negative clinical outcomes. In addition, cost management is a critical requirement: these vaccines are expensive and - in fragile, weakened supply chains and challenging operational conditions, the risk of waste is high.

It is therefore desirable to be able to monitor the vaccine cold chain. However, the locus of control may be vested more proximally, i.e., at the level of the Vaccine Manufacturer or Logistics Partner (often at the behest of the purchaser, e.g., Covax, Government, Insurer etc) of which there are many. As noted, there are at least 12 vaccines available in the market. Mezzanine can support a cold chain monitoring capability whereby mVacciNation users at VSP’s can capture fridge or container temperature and enter the data into the application. Mezzanine will not directly provide an IoT based cold chain sensor, but subject to a formal request from a client with an existing IoT solution in place (or envisaged), could integrate with such a solution through API; the data can then be displayed on the mVacciNation application.
