Scientists at the University of Copenhagen have discovered that
Vitamin D is crucial to activating our immune defenses and that
without sufficient intake of the vitamin, the killer cells of the
immune system - T cells - will not be able to react to and fight off
serious infections in the body.

For T cells to detect and kill foreign pathogens such as clumps of
bacteria or viruses, the cells must first be 'triggered' into action
and 'transform' from inactive and harmless immune cells into killer
cells that are primed to seek out and destroy all traces of a foreign
pathogen.

The researchers found that the T cells rely on vitamin D in order to
activate and they would remain dormant, 'naďve' to the possibility of
threat if vitamin D is lacking in the blood.
