vaccine manufacturing

Vaccine manufacturing involves producing biological preparations that help the immune system recognize and fight specific diseases. It starts with growing the active ingredients, such as weakened or harmless versions of the virus or bacteria, often using living cells in controlled environments. These are then purified to remove unwanted substances. The purified product is formulated into a stable vaccine, packaged, and tested for safety and effectiveness. The entire process follows strict regulatory standards to ensure quality and consistency, enabling vaccines to be distributed globally to prevent illnesses effectively.
