A rogue anti-vax nurse is being investigated after allegedly injecting up to 8600 people with a saline solution instead of a Covid-19 vaccine.
German authorities are now advising thousands of people to get another Covid-19 jab in case they received the dummy earlier this year.
A German Red Cross nurse is suspected of injected salt solution into people's arms instead of genuine Covid-19 vaccinations at a centre in northern Germany.
"I am totally shocked by this episode," Sven Ambrosy, a local councillor, said on Facebook as local authorities issued the call on Tuesday to about 8600 residents who may have been affected.
"Today I had the sad duty to inform around 8600 people who may have been affected that it cannot be ruled out they may have received a saline solution instead of their vaccination at their vaccination appointment.
