In Austria, public insurance requires scientific proof of effectiveness in order to reimburse medical treatments, but exceptions are made for homeopathy.[6] In 2004, Germany, which formerly offered homeopathy under its public health insurance scheme withdrew this privilege, with a few exceptions. In June 2005, the Swiss Government, after a 5-year trial, withdrew insurance coverage for homeopathy and four other alternative treatments, stating that they did not meet efficacy and cost-effectiveness criteria. However, following the result of a referendum in 2009 the five therapies were reinstated for a further 6-year trial period from 2012.[7]
