Whatever your doubts about the influenza vaccine, it is an established fact that immunization is many times — many times — safer than the flu itself. That does not mean flu is a plague, nor that the vaccine is perfectly safe. Nothing in medicine and little in life is perfectly safe. Harm from the flu vaccine is possible, but a highly remote risk. For what it may be worth to make this personal, I readily accept that risk every year not only for myself, but for my beloved wife and children as well. I put the arms of the people I love most on the planet where my mouth is on this topic.
