What are the different processing and display methods of different types of vaccines?

Different types of vaccines are processed and displayed in different ways. The following are some details about the processing and presentation methods of different types of vaccines:

1. virus vaccine: the virus vaccine is prepared by culturing and inactivating or attenuating the virus. This type of vaccine usually needs to be processed and displayed in the biosafety laboratory to ensure the safety of operators and the environment. During the treatment, the virus will be cultured and collected, and then inactivated or attenuated to prepare the vaccine. The final vaccine product needs to be purified and tested through multiple procedures to ensure its quality and safety.

2. Bacterial vaccine: Bacterial vaccine is made by cultivating and killing or weakening bacteria. This type of vaccine usually needs to be processed and displayed in a biosafety laboratory. During the processing, bacteria will be cultured and collected, and then vaccines will be prepared through death or attenuation. The final product needs to be purified and tested by multiple procedures to ensure its quality and safety.
