Flu Vaccine: What does the Science Say?

There is much debate about the flu vaccine.  Both 'sides' express great emotion regarding their beliefs.  I believe there are good intentions on both sides of this fence. However, beliefs and opinions aside ---- what does the science say? What is the evidence and proof for or against the flu vaccination?  

I believe that Dr James Chestnut's presentation covers the science, evidence, and proof extremely well.  He made this presentation to educate health care professionals and the 'lay' public alike.  The presentation represents a comprehensive review and explanation of the literature regarding both the influenza vaccination and vitamin D supplementation.
