In general, all of these strategies have shown advantages and disadvantages, and their use will depend on the knowledge of the mechanisms of infection of the target pathogen and of the immune response required for protection. Few parents today have even heard of all of the diseases we vaccinate against, let alone seen a case of the measles, diphtheria, or whooping cough. They can also be used on almost everyone who needs them, including people with weakened immune systems and long-term health problems. Basically, the common systems use for the production of recombinant proteins is the manipulation of mammalian cells, bacterial systems, yeast and etc. These different vaccine types will not be interchangeable. Industrial fermentation processes are largely classified as batch, fed-batch or continuous operations. They can trigger very strong immune responses in the body because they use a specific part of the germ. Misconception #2: "The preservative thimerosal makes vaccines risky.". Nat Med.
