The cold chain safety of vaccines is a global issue. The electronic vaccine vial monitor (eVVM) label can monitor the temperature of vaccines in real time and provide “early warning” prompts. In order to comprehensively evaluate the monitoring efficiency of eVVM, this study selected 75 eVVM labels and distributed them with a total of 600 vaccine vial monitor (VVM) labels of four different types in different experimental environment (2−8℃, −20℃ and 40℃), and used a temperature recorder as “gold standard”. The results showed that the accuracy of the eVVM labels and VVM labels in high temperature environment was as same as that of the temperature recorder (P = 0.195). The accuracy of low temperature anomalies report and high temperature anomalies report of eVVM labels was 100%, which was better than those reported by VVM labels. Therefore, eVVM labels have high monitoring accuracy, which is suitable not only for ordinary environments, but also for severe temperature environments. It should be helpful for the improvement of the efficiency and accuracy of cold chain monitoring.
