You truly have no clue what you speak of. Most peoples issues are a lack of vitamins and minerals. It effects the very small components in the body. People have deficiencies in Vitamin C, A, B, B complex, d , iron, magnesium, calcium, potassium and dozens more. All are linked to all facets of the body including the cells. The body craves those things, never heard it craving vaccinations.Vitamins and minerals don't interact with the immune system in that fashion.
A vitamin LITERALLY has nothing to do with the heavy and/or light chains of an antibody or activation of white blood cells for example.
Immune responses can be managed by exposure to inactivated versions of some diseases as has been experimentally shown.
