What Bottle Is The New Crown Vaccine Used In?

What bottle is the new crown vaccine used in?

There are three types of containers generally used to store vaccines: ampoules, vials and prefilled syringes. Many people who have participated in emergency vaccination in China said that the domestically-made new crown vaccines they vaccinate are all prefilled syringes, that is, syringes that have completed filling the vaccine. It is also understood that some vaccines currently used in production are also stored in vials.

Although it can be stored in different containers, the main reason for the tight supply of vaccine bottles is the limited production of glass for manufacturing bottles. Tao Lina said that because of public health, glass bottles containing vaccines must generally have the characteristics of low temperature resistance, high quality, and high stability. Such requirements determine that medical glass must be used in the packaging of vaccines. In the production of medical glass, whether it is the acquisition of raw materials, the intermediate processing, and the final transportation and storage, the cost is higher than that of ordinary glass, and the process requirements are more stringent.

At present, the materials used for medical glass bottles are mainly soda-lime glass and borosilicate glass. Medium borosilicate glass is an internationally recognized safe pharmaceutical packaging material, which not only fully guarantees the safety and stability of medicines, but also prevents medicines from becoming low-grade Adverse reactions in packaging that endanger human health are also the main choice of several major international pharmaceutical companies. But Taolina said that the medical glass in my country's domestic market is mainly low borosilicate glass and soda-lime glass, and the country is already promoting the replacement of medium borosilicate glass.
