Immune System

We have been taught that germs are bad and they are lurking around every corner, waiting for the opportunity to invade defenseless humans. We go to great lengths to combat these potential invaders; we employ frequent hand-washing with copious amounts of soap and grimace at the thought of eating a morsel of food picked up from the floor. Doctors and the media discuss the flu season as though getting the flu is inevitable unless, of course, you get a flu shot. But similar to other unquestion-ingly accepted medical concepts, convincing us that humans have a frail immune system that must be strengthened by vaccines is a medical myth. A better understanding of the symbiotic relationship between humans and microbes is long overdue.
