Chapter 21

Kostas remembered getting the flu (influenza) last winter: coughing, fever, achiness all over his body, watery eyes, and fatigue. He felt awful but he argued, “What’s the point of a flu shot, when all it does is give you the flu?” Kostas did not understand that the flu vaccine is a combination of several inactivated (killed) viruses injected into muscles in your body (usually in your arm). No live viruses are injected. So, as for the injected form of the vaccine “causing” the flu- people who claim that could already have been exposed to a flu virus before the vaccination or could have been exposed to one of the strains not included in that year’s vaccine. Some people produce a mild immune reaction that can be mistaken for the flu. In the end, Kostas relented and got his flu shot.
