GP found guilty of professional misconduct over pandemic-era social media posts criticizing public health measures
Marcus de Brun, a GP and former member of the Medical Council, has been found guilty of professional misconduct following a seven-day inquiry into 10 allegations related to 67 social media posts made between May 2020 and October 2021. The posts criticized Covid-19 vaccines (particularly for children), lockdowns, facemasks, and public health authorities. Seven allegations were upheld, four of which were deemed 'disgraceful and dishonourable' by a Medical Council fitness-to-practise committee. The findings also relate to his attendance at a large public rally in Dublin on August 22, 2020, where he failed to wear a mask or maintain social distancing. The inquiry chairperson described some of his statements as 'grossly irresponsible' and 'reckless,' particularly those suggesting vaccination of children amounted to child abuse. De Brun claimed his concerns were ignored by regulators, prompting his use of social media. The case continues as both sides submit arguments on appropriate sanctions.
All three sources agree on the core facts of the case, but differ significantly in depth and framing emphasis. Irish Times provides the most complete and contextualized reporting, including reach and additional quotes. TheJournal.ie includes strong emotional quotes from both de Brun and the inquiry chair but lacks context on follower growth. RTÉ offers the most minimal, procedural coverage, omitting key contextual and emotional elements.
