Eight workers in care homes in Germany have accidentally received five doses of the Covid-19 vaccine, without suffering serious disease effects so far, local authorities announced Monday.
The employees, seven women and a man between the ages of 38 and 54, work in a nursing home in the town of Stralsund in north-eastern Germany.
They are among a priority group and among the first to receive the Pfizer-Biontech vaccine, which Germany began rolling out at the end of last week.
But while they were vaccinated on Sunday, they were each injected with five doses at one time, said Stephan Kirth, the facility’s district manager.
Kirth said employees were promptly notified of the error.
Four of them were taken to hospital for medical observation after showing mild flu-like symptoms, while the others were sent home.
“I am deeply sorry for this incident,” said Kirth, adding that the error was an isolated case and related to human error.
He continued, “I hope that not all of the injured suffer from serious side effects.”
Ahead of the launch of vaccination campaigns in several European countries at the end of the week, the German company Biontech reported that larger-than-usual doses were injected during the trials without serious side effects on the volunteers.
The vaccine is delivered within less than a year and is designed to be administered in two injections, in vials of five doses each once diluted.
However, a Ministry of Health spokeswoman said Monday that each vial can be used to give up to six doses.
