Symptom narrative

Yellow fever vaccine was administered to the patient on 4/26/25. It is for a family of 4. The mother came on 5/2/25 to pick up a prescription and upon counseling, I asked how the family was. The mom then told me that patient had an allergic reaction to the YF vaccine 20 minutes later while they were grocery shopping. Patient felt itching on his body. She then gave him Benadryl to take. Still a few minutes later, he was still complaining and swelling of the face and neck was observed. He complained of difficulty breathing. They took him to ER. In ER they administered Epi-pen and Solu-medrol. He was in observation for 4 hours. Swelling went down. Released him with an oral Prednisone. Mom was somewhat okay when I saw her on 5/2/25 and the 3 other family had no reaction whatsoever.
