An anti-vaxxer nurse in Germany has allegedly injected up to 8,600 people with saline solution instead of a Covid-19 vaccine.

The Red Cross nurse may have given thousands of elderly patients in northern Germany a fake jab in the early Spring, a police investigation found.

Authorities on Tuesday urged thousands of people who received their first jab at a vaccination centre in Friesland – a rural district near the North Sea coast – to get another shot of the Covid-19 vaccine after making the discovery.
