Clinical Approach Used in Medical Consultations for Allergic-Like Events Following Immunization: Case Series Report in Relation to Practice Guidelines

Conclusions Most ALEs after immunization are not suggestive of anaphylaxis and should not be managed as such. The definition of anaphylaxis in the JTFPP guidelines is nonspecific and may need to be revisited. Restricting skin testing and graded dose reimmunization to patients whose ALE onset is ≤1 hour (compatible with IgE-mediated reaction) and to those meeting specific clinical criteria for anaphylaxis (whatever the timing) is likely a sufficiently sensitive and cautious approach.
