I administered a Fluzone and Comirnaty vaccine to patient. He stood up and he was standing by his mom in the counseling room. Suddenly, he slumped over slowly and turned very pale. We laid him on the ground gently (no injuries occurred) and he took some deep breaths. We gave him a cool cloth for his neck, some water, and a lollipop. He had no trouble breathing. After about 10 minutes in the counseling room, his color returned and he was able to walk to the waiting area. He and his mother waited for another 15 minutes and he was fine. We offered to call EMS, but mom declined.
