Parents Unconvinced of Vaccine Safety

No matter how many times the medical community reassures parents that vaccines are safe and necessary to prevent life-threatening diseases, some people remain unconvinced.
"I believe that herd immunity is a complete myth," says J.B. Handley, co-founder of an autism advocacy organization called Generation Rescue that is critical of the way vaccinations are carried out in the U.S. "It's a tactic used to scare the public."
Handley, a father of three in Portland, Ore., has an 8-year-old son with autism. He believes that the cocktail of immunizations his son received when he was 13 months old is to blame
