> The delayed use of epinephrine, identified as a significant feature in several reports of fatal food anaphylaxis, is perhaps the risk factor most amenable to modification. This has, in part, driven the widespread provision of epinephrine autoinjectors for the management of anaphylaxis, although controversy exists as to their use in less severe, nonanaphylactic allergic reactions.

Your logic seems to be "because anaphylactic deaths are low, epipens generally aren't useful". It may be true that they're used too often - knowing what to do in the moment when your kid is swelling up, having trouble breathing, throwing up, or passing out, especially if they're very young or not verbal, is a challenge and an experience I don't wish on anyone. But the way I interpret the data is that anaphylactic deaths are low precisely because epipens are so commonly used and there is so much awareness and training around when/how to use them.
