A young Italian woman mistakenly received six doses of the vaccine on Sunday coronavirus covid-19 of Pfizer-BioNTech and although he is in good health, he was under observation in a hospital in Tuscany (center), the AGI agency reported on Monday.

The error occurred when a nurse, instead of injecting a dose of the vaccine to the 23-year-old medical student, administered the entire vial, equivalent to six doses, according to the same source.

According to AGI, experimentation on the effects of a possible Pfizer-BioNTech vaccine overdose was limited to four doses so this six-dose case is unknown in the medical literature.
