A 23-year-old Italian woman received 6 times the recommended amount of Pfizer’s coronavirus vaccine

A 23-year-old Italian woman received six doses of Pfizer’s coronavirus vaccine on Sunday, after a nurse at a hospital in Tuscany accidentally injected an entire vial.

The Italian news agency AGI reported the incident on Monday, and USL Toscana Nord Ovest, a health network in Tuscany, acknowledged it in a press release.

Pfizer’s shot is supposed to come in two doses, administered three weeks apart.

The woman is in stable condition after receiving fluids and the pain reliever paracetamol, AGI reported.

Nigel William Crawford, the director of SAEFVIC, the vaccine-safety service in Victoria, Australia, said vaccine overdoses aren’t likely to cause serious adverse reactions.

“I often say ‘you can’t have too much of a good thing’ when it comes to vaccines,” Crawford wrote in The Conversation.

Even five or six doses, he added, is “still a relatively small amount and not likely to be harmful.” Side effects from the shot, though – such as fever or pain at the injection site – may be heightened, Crawford said.

Previous vaccine overdosing incidents haven’t seemed to cause any life-threatening outcomes. In April, dozens of inmates at an Iowa prison received six times the recommended vaccine dose. Cord Overton, a spokesperson at the Iowa State Penitentiary in Fort Madison, told The New York Times that none of the inmates had been hospitalized, though many were experiencing side effects such as body aches and fevers.

Similarly, an employee at the Singapore National Eye Center received five doses of Pfizer’s vaccine in February. The person was taken to a local hospital for observation and was discharged two days later.

That same month, an 88-year-old man and a 94-year-old woman in Brisbane, Australia, received four times the recommended dose of Pfizer’s vaccine. They did not experience any serious adverse reactions. Australia’s federal health minister, Greg Hunt, said the doctor who performed the injection hadn’t received the mandatory immunization training.
