The 23-year-old Italian who was mistakenly administered several doses of the Pfizer vaccine received four, not six as initially announced. Italian health authorities corrected this information on Tuesday.
This Sunday, a young clinical psychological intern received an incorrect dosage of the Covid-19 vaccine in Tuscany. The young woman was able to return to her home on Monday after spending 24 hours in hospital observation. It remains under control in case this overdose creates health problems.
An oversight on the part of the nurse
The Italian actually received “only” 0.30 ml, “the amount used for four doses of the Pfizer vaccine,” the Tuscany health agency said in a statement. “The fact that the quantity injected is slightly greater than four doses is important because the experimentation carried out by Pfizer to establish the consequences of an overdose had stopped at four doses of active principle inoculated simultaneously, without this having any particular consequences. for patients. “
This error is due to the fact that the nurse in charge of vaccination forgot to dilute the vial of active principle with physiological serum. An oversight due to “routine activity on high volumes and under pressure due to the need to strictly respect deadlines,” said the press release.
