Symptom narrative

During Hep B vaccine, Pt reported feeling warm and looked anxious immediately after recieving the vaccine. I waited a few minutes for the patient to calm down and she told me when she was ready to revieve the next vaccine. During the Tdap vaccine, Pt experienced brief syncope and vomited after the vaccination. Pt reported feeling very warm and her cheeks were flushed. This happened within a minute after the Tdap vaccine. Her boyfriend who was with her caught her and she regained consciousness within that brief moment. Her blood pressure was taken and she was given oral fluids (Gatorade). After several minutes of observation by myself and my supervising Pharmacist, she was advised not to recieve the last vaccine she asked for (MMR) until the following day. She went home and reported feeling no further symptoms the following day.
