Myth 1: It's better to get immunity by getting naturally infected with a disease than by a vaccination.
Reality: It's much safer to get immunity from a vaccine, since diseases cause suffering and can cause permanent disability or death.
Myth 2: Since polio has been eliminated from the United States, it's not necessary to get the vaccine.
Reality: Polio still occurs in many other countries in the world. A traveler could bring the disease to this country and start an epidemic. If Americans weren't vaccinated, we would all be at risk.
Myth #3: Vaccines aren't 100 percent effective, so why bother?
Reality: In an outbreak of measles, for example, only 1 to 2 percent of immunized people will get the disease; but 44 percent of unimmunized people will become ill and risk permanent disability or death.
