Vaccine Manufacturing: Purification to Packaging

Vaccine manufacturing turns cultured microorganisms into a safe immunological product. The process starts with growing viruses or bacteria to collect antigenic material, which is the part of the pathogen that helps trigger an immune response.

Vaccine production begins by cultivating pathogens, such as viruses or bacteria, to generate antigens.

For viral vaccines, particularly whole virus vaccines, host cells, such as mammalian cells, are grown in bioreactors and infected with the virus.

The virus replicates inside host cells, which are then lysed to release the viral part...
