Patient received vaccine approximately 1:10pm. Was seated when reported feeling dizzy around 1:15pm. I immediately elevated patient’s legs, gave the patient some water, and patient reported to start feeling better right after. Patient remained seated with legs elevated for 30 minutes. Patient said never had this kind of reaction to vaccination in the past. Advised patient that this was most likely a vasovagal reaction, and that it can happen to anyone at any point in time in the minutes after any vaccination, regardless of whether or not it happened in the past. Also advised patient to report to primary care doctor what happened and to inform immunizers about dizziness when getting vaccines going forward. Patient felt better and left around 1:45pm without further incident.
