To receive the overdose, as explained by the ASL, a sixty-year-old woman: she would be in good health, according to the health authority.



A similar case also occurred in Tuscany, in Massa, on May 9: at that time it was a 23-year-old who received 4 doses of Pfizer. A "cognitive slip", explains the ASL, in the vaccine preparation phase, which was contributed to by a problem of counting and preparing the syringes when preparing the vaccination session, in a routine activity at high volumes and with pressure due to the need for strict compliance with the times.
