The New Crown vaccine is not carried directly in a syringe and is drawn directly when it is required to be injected. Currently the injectable New Crown vaccine is kept in an ampoule, and only when an injection is needed is a syringe used to draw from the ampoule and then inject it. The use of ampoules makes it easier to store, transport, etc., and ensures that the vaccine does not deteriorate and is more convenient to use. If the vaccine is stored directly in a syringe, on the one hand, there is no guarantee that there will be no leakage during storage and transportation, which would render the vaccine ineffective. In addition, ampoules have been used in the clinic for a longer period of time and in a wider range, which makes it more convenient for medical personnel to operate, therefore, taking ampoules for preservation and transportation is the main preservation method at present.
