An 80-year-old female patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, lot number: EL324, expiration date: Apr2021), intramuscular in the left arm, on an unspecified date, at 0.3 mL, single for COVID-19 immunization, at the nursing home.

Historical vaccine included a flu shot received in October (year not provided) for immunization with no adverse event. The pharmacist reported the inadvertent administration of the COVID-19 vaccine to the patient, by a nurse. She stated that the patient received "0.3 ml of the undiluted vaccine" (Failed to ask if it was the patient's first or second dose). The pharmacist asked for recommendations to monitor the patient post-injection. The patient was given 5 times the normal dose (one undiluted vial), vaccine was undiluted. The reporter said that the pharmacy had given 5 times normal dose of the COVID vaccine, undiluted, and reporter wanted to know what was suggested that they do. On 03Feb2021, the pharmacist reported that she was mixing the vials for administration. She stepped away and a nurse pulled an undiluted vial and gave patient 1 dose from undiluted vial with purple top still on. The pharmacist confirmed that the patient received 0.3 mL of undiluted vaccine, not the full vial. The patient's doctor was also there when it happened, and they both stayed with her for about 3 hours after it happened to monitor the patient. The patient had sore arm and felt tired on an unspecified date. Most of her friends felt the same way after getting the Covid vaccine. No other adverse event experienced since then.
