Photographs of Czech anti-vaccination activists wearing yellow Stars of David bearing the words "untested and unvaccinated" have sparked anger.

The images were posted on Twitter by BBC Prague correspondent Rob Cameron, who commented that the anti-vaxxers were plumbing “new depths of idiocy and crassness… 80,000 Bohemian and Moravian Jews were murdered in the Holocaust.”

The yellow badges were notoriously used by the Nazis to mark out and discriminate against Jews.

One Czech social media user wrote in reaction, “It seems to me that they have absolutely no idea what the suffering of the Jews was.”

Another wrote: “I'm sick of it and I don't understand the audacity… It's spitting in the face of the survivors and their descendants. And all the people who went through that hell.”

A survey by STEM, a local polling organisation, in early December, found that only 40 per cent of Czechs would willingly be vaccinated, among the lowest rates in Europe.

At a rally against the coronavirus lockdown in Prague in October last year, police used water cannons and tear gas to disperse protesters after violence flared.
