Childhood food allergies are the most common cause of anaphylaxis (a "severe allergic reaction that is rapid in onset and may cause death"). A decade-long analysis of billions of health care claims reported a nationwide increase of 377% in claims for anaphylactic food reactions, and a separate analysis of emergency department (ED) visits over roughly the same period documented a 214% increase in visits for food-induced anaphylaxis—observed in children of all ages but with the highest rates in infants and toddlers. Peanut and tree nut allergies—which have tripled since 1997—are the most frequent triggers of ED visits for anaphylaxis, and over a third (35%) of the children who experience peanut-related anaphylaxis do so following their very first exposure.

… multiple strands of published evidence—including experiments dating back over a hundred years—indicate that injected vaccines are major culprits.

Whereas there is widespread agreement that these food allergy trends spell out bad news for children and families, there is little consensus on the epidemic's supposedly "enigmatic" causes. This declared bafflement is itself puzzling because—as Children's Health Defense has written previously—multiple strands of published evidence—including experiments dating back over a hundred years—indicate that injected vaccines are major culprits.
