Vaccine Debate Troubles Parents

CHEYENNE, Wyo. -- For some people, vaccinating infants and children against preventable disease is a part of childhood, like baby teeth and tricycles.
But critics say vaccines cause more harm than good. Vaccinations can have dangerous physical side effects, they add.
Such conflicting messages can create a dilemma for parents as they wonder what to believe.
A national survey released in June of 376 households found that 80 percent of parents are uncomfortable getting their children vaccinated. Still, 95 percent said they would get the vaccinations.
