An incorrect vaccine formulation was administered, resulting in a higher-than-authorized dose for the patient. The patient received Moderna Spikevax 12+ years (0.5mL) instead of the intended Moderna Spikevax 6 months?11 years (0.25mL) formulation. Following discovery of the error, I contacted both the vaccine manufacturer (Moderna) and the CDC for guidance. Per their recommendation, the administered dose is considered valid, and no repeat vaccination is required. The patient may, however, experience increased side effects such as fever, fatigue, headache, or localized injection site reactions. ? Will notify patient?s parent of the incident and advised on possible side effects, symptom monitoring, and when to seek medical attention if needed. ? -Called and spoke to patient's mother who reported that patient felt tired and "crummy" for approximately 24 hours after receiving the vaccine. Mom asked patient how she was feeling while on the phone with me and patient told mom her arm was still a little sore but otherwise felt fine.
