In the production and transportation of animal vaccines, the selection of veterinary vaccine bottles plays a crucial role. It not only affects the storage and transportation quality of the vaccine, but also directly relates to the effect of animal immunization. Different types of vaccines have different requirements for bottles, and today we will focus on the special needs of inactivated and weak vaccines for packaging materials and how to ensure the best storage environment for vaccines.

1. Inactivated vaccines and plastic vaccine bottles

Inactivated vaccines are made by physically or chemically treating pathogenic microorganisms so that they lose their pathogenicity but are able to stimulate an immune response. This type of vaccine is usually used to prevent and control a variety of animal diseases, such as swine fever, foot-and-mouth disease and so on. Inactivated vaccines are characterized by their higher stability and less stringent storage requirements, but care must still be taken to avoid spoilage of the vaccine due to low temperatures.

Inactivated vaccines require less stringent bottle materials. Generally, plastic bottles are used as the containers of vaccines, because the plastic material can well prevent the bottle from rupturing and has better sealing performance. When choosing bottles, veterinary enterprises need to pay special attention to the quality of the bottle to ensure that it is strong enough to prevent breakage during transportation. Particularly during storage, vaccines should be prevented from freezing, as temperatures below 0°C will affect the effectiveness of the vaccine, so the material of the bottles needs to be able to remain stable in different temperature environments.

2. Adaptation of weakened vaccines to glass bottles

Weakly virulent vaccines are made by treating the pathogenic microorganisms so that they lose their pathogenicity or trigger only a mild reaction, but still able to stimulate an immune response. It is usually used for long-term immunization or to enhance the immunity of stronger animals, such as poultry, livestock and so on. Weakly-virulent vaccines have a good immunization effect that lasts for a long period of time, so when selecting vaccine vials, special attention needs to be paid to their adaptability to temperature and pressure.

Unlike inactivated vaccines, weakly-attenuated vaccines usually require the use of glass vials for packaging. Glass vials have a higher stability against temperature and pressure changes and are particularly suitable for storing active vaccines that require autoclaving at high temperatures. At high temperatures, glass vials are less prone to deformation, ensuring that the active ingredients of the vaccine are not damaged. In addition, the transparency of glass vials also allows the appearance of vaccines to be clearly inspected, which reduces hidden quality risks.

3. Influence of storage environment on vaccine quality

Whether it is inactivated vaccine or weak vaccine, the correct storage temperature and environment are crucial to the quality and effect of the vaccine. The appropriate storage temperature for inactivated vaccines is 2-8℃, but freezing should be avoided. If the vaccine is stored at low temperatures, it may lead to changes in the active ingredients of the vaccine, which in turn may affect the immunization effect. Therefore, the packaging vials of vaccines should be able to effectively prevent the vaccines from being frozen or disturbed by other external environmental factors.

Although weak vaccines have higher requirements for temperature when stored, the sealing and temperature resistance of their packaging bottles are particularly important. Only by ensuring that the sealing of the packaging bottle is intact can we prevent the active virus from being destroyed due to changes in the external environment, thus ensuring the immunization effect of the vaccine.

4. Veterinary vaccine bottle quality assurance

For veterinary enterprises, the choice of suitable vaccine packaging bottles is not only the appearance of the product is considered, but more on the vaccine storage, transportation and immunization effect of the guarantee. Enterprises in the purchase of packaging bottles, should choose the quality of bottles, in line with the relevant safety standards. In addition, the production process of packaging bottles should also comply with the GMP (Good Manufacturing Practice) requirements to ensure that each batch of vaccine bottles can be fully inspected during the production process, to avoid affecting the quality of vaccines due to the quality of packaging problems.

The choice of packaging vials for veterinary vaccines directly affects the immunization effect and storage safety of vaccines. In the choice of vaccine bottles, manufacturers need to be based on the characteristics of different types of vaccines, choose the right material, such as plastic bottles suitable for inactivated vaccines, glass bottles suitable for weak vaccines. At the same time, reasonable control of the storage environment temperature, and to ensure that the bottle has good sealing and temperature resistance, in order to ensure the quality of vaccines and immunization effect.
