This guy is full of crap. He's slick, but he is not giving accurate information. I know what he is saying is unsupported by the scientific research because I looked at the vitamin D claim extensively only a couple months ago.Another "Quack" like Dr Blaylock , neurosurgeon, on D3 for swine flu and the immune system:

Yep; you can just Tell he's a quack too.....
The vitamin D claim is not backed up by research. It is currently only an hypothesis to explain why influenza epidemics occur in winter. But then why is there influenza in the tropics? Why are there influenza outbreaks on cruise ships in the summer? The latest pandemic emerged in Mexico first. There is no shortage of Sun in Mexico and besides, the pandemic emerged in April! It spread in the northern hemisphere in summer!
In addition, a severe deficiency in vitamin D affects the immune system but that does not mean excessive vitamin D improves the immune system. Nor does it mean everyone is vitamin D deficient in the winter.
The hypothesis about vitamin D is interesting. But this idiot claiming it is a fact demonstrates his ignorance. And saying we don't get colds in the summer? Yes, people do. Quite often, actually.
Fall outbreaks of upper respiratory infections begin like clockwork, exactly when schools go back in session. Gee, what a surprise.
Why influenza epidemics in particular are more frequent in winter rather than the fall is not clear. It may be much more important that people are confined indoors with each other than even the more common hypothesis that the virus is more stable on surfaces in the winter. A very small study of an outbreak of the 2009H1N1 flu in a tour group found face to face contact with the index case was the most important risk factor. Only one person who sat near the index case on a plane got infected and of all the people on the tour bus, the people who contracted the infection remembered talking to the index person, while others on the same bus who did not recall face to face conversations did not get sick.
