On Tuesday, Sep 9, a prominent German Jewish group and AIDS prevention advocates demanded the withdrawal of the ad.
"It is disgusting and we're asking the producers of the campaign to pull it back," said Joerg Litwinschuh of German AIDS Assistance, an awareness group.
He said the ad, commissioned by Regenbogen, German for rainbow was offensive to people living with HIV.
"We denounce this ad. I can say that absolutely," said Volker Mertens, a spokesman for another group, the German AIDS Foundation.
Stephan Kramer, general secretary of the Central Council of Jews in Germany, termed the ad as 'a defamation and mockery' of Holocaust victims.
