John Lorimer Campbell is an English YouTuber and retired nurse educator who has made videos about the COVID-19 pandemic. Initially, the videos received praise, but they later diverged into COVID-19 misinformation.[1] He has been criticised for suggesting COVID-19 deaths have been over-counted,[2] repeating false claims about the use of ivermectin as a COVID-19 treatment, and providing misleading commentary about the safety of COVID-19 vaccines.[3]
