In July, the board general practitioner Benoît Ochs for one year over accusations that he treated patients with medications after these were found to be ineffective against Sars-CoV-2 and raising doubts about vaccine effectiveness and the safety of masks.

Ochs is one of three cases investigated by the medical board, the Collège Médical, the body’s president, Pit Buchler, told public broadcaster Radio 100,7 on Monday.

In the other two cases, the probe is still ongoing, Buchler said. Patients had reported the GPs for contradicting public health policy--in particular questioning the vaccine and the wearing of masks. The identity of the two doctors has not been made public.

Ochs was cheered on during a “Marche Blanche” in Luxembourg in October and has contributed to Expressis Verbis, a group that has been widely panned as a platform for coronavirus deniers.

In a June video, the doctor said he is neither pro nor anti-vaccine but described himself as being cautious. Ochs cited a book by French physician Didier Raoult, who came under scrutiny during the pandemic for promoting hydroxychloroquine against covid-19 despite scientific evidence against its use.

He has filed an appeal against his suspension, saying he always acted in his patients’ best interest, with a verdict due in December.
