A German nurse is under investigation after allegedly injecting thousands of people with a fake “coronavirus vaccine”, according to Reuters.

Police investigator Peter Beer said there was “a reasonable suspicion” that the rogue medical professional had administered shots of saline solution to up to 8,600 patients who were slated to receive the COVID jab.

The saline solution itself is harmless, however most people vaccinated in Germany during March and April are high elderly people.

The nurse had previously aired sceptical views about vaccines in social media posts, police investigators said.

Authorities have implored people who may have been victims of the nurses placebo jabs to get a second jab.

“The district of Friesland will do everything possible to ensure that the affected people receive their vaccination protection as soon as possible,” Ambrosy wrote in a Tuesday Facebook post.
