"John Lorimer Campbell is an English YouTuber and retired nurse educator known for his videos about the COVID-19 pandemic. Initially, the videos received praise, but they later veered into misinformation.[2] He has been criticised for suggesting COVID-19 deaths have been over-counted, repeating false claims about the use of ivermectin as a COVID-19 treatment, and providing misleading commentary about the safety of COVID-19 vaccines (emphasis mine). As of June 2023, his YouTube channel had 2.8 million subscribers and over 653 million views"
