Doctors tend to wave off all fears of vaccinations, concerned that ignorant or misled parents will not protect their kids from diseases that don't need to happen.
But there are a variety of vaccine-related fears out there. For example, some parents of autistic children know what they have experienced and are convinced that somehow, directly or indirectly, vaccinations harmed their children. Most disturbingly, voices here and there cry out about the use of aborted fetal cells in vaccines.
The allegations are serious but the evidence is either not decisive or not well known. When should a Christian be satisfied?
