Vaccines have low risk of serious side effects: study

Some childhood vaccines are linked to serious side effects, but they are quite rare and do not include autism, food allergies or cancer, said a review of scientific literature Tuesday. A host of vaccines commonly given to children under age six were the focus of the systematic review of rigorously conducted studies, published in the peer-reviewed US journal Pediatrics. The report seeks to address a rising trend of vaccine hesitancy among parents in the United States and Europe, which has led to a resurgence of measles and whooping cough in some parts of the world. "We found that serious adverse events that are linked to vaccines are really rare, and that when they do occur they are often not necessarily severe," said study co-author Courtney Gidengil, a pediatrician at Boston Children's Hospital and professor at Harvard Medical School.
