They asked me what I thought. So I grabbed the worm can and opened it: "If it was me, I would not get the flu shot. Studies have shown that they are not that effective and, in fact, carry potential risks. I strongly recommend against them." The patient looked at me with dismay and asked what he should do. I said, "The best flu defense is the proper function of your own God given immune system. The simplest way to do that is by optimizing your vitamin D intake. In addition, limit your grain and sugar intake. A sure fire way to boost immune function is to exercise regularly and get enough sleep. Yeah, I know. It sounds too simple and is not as glamorous as some drug or vaccine. But it is safe and effective. You asked. Your choice."
