Symptom narrative

received the second dose of HEP B vaccine in the office around 1 pm. Shortly after, around 2 pm, the student returned to the clinic to inform us that she was experiencing hives and difficulty breathing. The student was promptly triaged and assessed, with notable hives on the bilateral arms, neck, and face, and was visibly experiencing breathing difficulty. VS stable (135/84, HR 88, sats 100%). The student informed us that she took Benadryl PO 30 minutes prior, which helped slightly with her hives. EMS called on site and took the student to the ED.
