A nurse in Italy accidentally administered six doses of the Pfizer COVID-19 vaccine to a single-shot patient, according to CBS News.

The 23-year-old patient received the vaccine Sunday morning and was observed at Tuscany’s Noa Hospital for 24 hours. She was given fluids and anti-inflammatory and fever medications and was released on Monday. He did not experience any adverse reactions.

“This person at this time will surely have no side effects,” Antonella Vicenti, MD, director of infectious diseases at Noa Hospital, told reporters.

Each vial of Pfizer vaccine contains six doses. Each dose is extracted individually and placed in separate diluted vials. On Sunday, the nurse who administered the vaccine injected the full amount of an undiluted vial.

The nurse noticed the mistake and immediately reported it to the patient and the attending physician, who began monitoring the woman’s adverse reaction, CBS News reported. They also alerted local health authorities and the patient’s family.

Pfizer studies have found that people who receive up to five times the normal dose have no additional reactions, Vicenti said. In addition, patients in Israel and Germany who have accidentally received six doses have shown no adverse reactions, CBS News reports.

“The patient had no fever and presented no pain except pain at the site of inoculation, or any other manifestation,” he said. “I was a little scared, so we preferred to keep her here until this morning.”

The hospital will test the patient’s blood regularly to monitor their immune response and long-term effects, CBS News reports. The hospital has also initiated an investigation to review safety procedures.

“This is something that should never happen,” Tommaso Bellandi, director of patient safety at the health authority in northwestern Tuscany, told the newspaper.

“Unfortunately, because of our boundaries as human beings, as well as organizational boundaries, these things can happen,” he said.
