The difference between plastic vaccine bottle and glass in application

 Animal vaccines are of great significance in preventing various diseases, blocking the spread of infectious diseases, and ensuring the healthy development of animal husbandry. There are many types of animal vaccines. We will find that some vaccines are packaged in plastic vaccine bottles, while some vaccines are packaged in plastic vaccine bottles. What is the difference between the two kinds of packaging for the selected glass vaccine bottle?

Animal vaccines are divided into inactivated vaccines and live vaccines due to their antigenic properties and different preparation techniques. Inactivated vaccines, also known as dead vaccines, are vaccines made by using physical or chemical methods to treat microorganisms so that they lose their infectivity or toxicity and maintain good immunogenicity. It has the characteristics of being safe and not returning to ancestors and being strong. This vaccine does not have high requirements on the storage environment. The suitable storage temperature is 2-8℃. During the storage process, the vaccine must be strictly prevented from freezing. It cannot be stored below 0℃, otherwise it will cause the inactivated vaccine to deteriorate and affect the immune system. Effect. Different from the single-dose packaging of live vaccines, the packaging capacity of this type of vaccine is generally relatively large, and the glass material is easily broken during transportation, so plastic vaccine bottles are often used to store inactivated vaccines.

Live vaccines generally need to be stored at a low temperature, especially freeze-dried vaccines need to be below -15°C. The lower the temperature, the longer the storage time. Such vaccines are generally subjected to high temperature and high pressure sterilization. Relatively speaking, the high temperature and low temperature resistance of glass materials are more suitable for storage of such vaccines.
In addition, plastic vaccine bottles are generally processed from polyethylene or polypropylene materials, which have good barrier properties and corrosion resistance to acid and alkali solvents. The vaccine diluent is generally physiological saline, and this type of packaging can also be selected.
