Vitamin D lessens the chance of catching a cold?

From the CNN.com article:
One reason vitamin D is so interesting is that unlike other vitamins, vitamin D acts as a hormone in the body and is known to help regulate at least a thousand genes, said Melamed. It's a cell-signaling molecule that may play a role in controlling the immune system, fighting cancer, improving cardiovascular health, and possibly regulating blood sugar. (There are vitamin D receptors in blood vessels and in the pancreas, which regulates blood sugar.)

For now, the jury is still out on vitamin D's link to respiratory infections. But it's a tantalizing link.
