A 23-year-old Italian woman was observed in a hospital in Tuscany after a nurse mistakenly gave her six doses of the Pfizer-BioNTech’s COVID-19 vaccine, Euro News reported.
She was released on Monday and did not suffer any adverse reactions according to local health authorities. Doctors said she was given fluids and paracetamol after the injection on Sunday.
Instead of injecting just one dose into the medical student’s arm, a distracted nurse mistakenly injected the entire vial, which is equivalent to six doses.
“This person at this time will certainly not have side effects,” said Dr. Antonella Vicenti, director of infectious diseases at Noa Hospital.
Previous studies to test overdoses of the Pfizer vaccine were limited to four doses, according to news agency AGI. Vicenti said Pfizer studies had shown people who had received up to 5-times the normal dosage did not suffer any consequences.
Since there is no knowledge of a person being given six doses, the patient is being kept under close observation to see whether there are any long-term effects.
