More than half of parents worry about vaccine safety when it comes to their kids.
A new university of michigan report says fifty-four percent of parents worry about serious side effects.
However, ninety-percent believe vaccines are a good way to protect their kids... And eighty-eight percent follow their doctor's vaccine advice.
The researchers say parental concern has led some to postpone vaccines in their kids... Or forego them all together.
The researchers believe when parents refuse vaccines, they're putting their children at risk for potentially life-threatening diseases.
The study also found one in five parents believe vaccines cause autism, despite several previous studies discrediting that theory.
