This is visibly easy-checked vaccine vial for both nurses and people who have to be vaccinated. The front of vaccine vial’s nanofiber film will be clear little by little when it is exposed at room temperature because of the feature of nanofiber film that turns clear at room temperature. When the front of the vaccine vial gets clear, the ‘X’ will show up which was placed under the nanofiber film so that people can see whether the vaccine has deteriorated or not. By showing the vaccine’s condition visibly, it can raise confidence for people who have to be vaccinated and raise the vaccination rate.
