“…Whilst not every study focused on the effectiveness of cold chain protocols, several identified the need for more comprehensive guidelines and planning surrounding cold chain. From a public health perspective, this would enable a decreased risk of errors, the prevention of cold chain breaches, excursions and failures and an increase in safety when storing, handling and administering vaccines (Chiodini, 2014;Clancy et al, 2017;Kosari et al, 2018;Ministry of Health, 2016;Turner et al, 2011). However, it is also important to note that some studies also investigated education programmes surrounding cold chain prractices yet did not identify significant changes following programme implementation (Datkuliak & Chichester, 2014;Hazelton et al, 2002;Thielmann, Viehmann, & Weltermann, 2015).…”
