Vaccines should be stored and transported cryogenically, and the optimal temperature required for different types of vaccines varies. Take the existing new crown vaccines as an example: the optimal temperature of most mRNA vaccines is -20°C, and some even require deep refrigeration as low as -70 to -80°C; the optimal temperature of inactivated vaccines is 2 to 8°C, these vaccines will be ineffective if they exceed 8 degrees.
During the pandemic, while accelerating COVID-19 vaccine development or distribution, disciplined vaccine management is required at every stage to minimize waste. This requires that vaccines be transported and stored under strict monitoring, and if they are damaged by heat, you can check whether the vaccines are still effective by looking at monitoring equipment.
