NEW - Support for the discussed compulsory vaccination of the general population is crumbling in Germany amid Omicron. Gassen, head of the Association of Statutory Health Insurance Physicians: "Enforcement and execution not a task of medical practices, but government task." Gaß, chairman of the German Hospital Association: "Corona could be treated like the flu. No need for compulsory vaccination in that case." Streeck, virologist on Corona expert panel: "Mandatory vaccination problematic from a medical point of view. No sterile immunity."
