Mistake #4: Not Recognizing a Vaccine Reaction – A Serious and Preventable Risk

Nearly 50% of Vaccine Injuries Could Be Avoided—If Parents Knew What to Look For

It has been estimated that half of all vaccine injuries could be prevented if parents and doctors knew how to recognize early warning signs of a reaction. The problem? Most parents are never told what to watch for—and too many doctors dismiss concerns without proper investigation.

"It couldn't be the vaccine. Just a coincidence."

This isn’t just a small mistake—it’s a serious, preventable risk that can have lifelong consequences.
