Posters here are understandably very suspicious about being lied to or manipulated by people with an agenda.
Just putting it out there that you should extend this skepticism to John Campbell.
He's a nurse with a PhD in "online education" who initially promoted accurate educational videos in the pandemic. He gradually moved to pushing conspiracy theories & other clickbait - most of the claims in his videos are not true, but get lots of views.
Because his channel is monetised, he makes £10,000+ each month, and is therefore actively incentivised to push controversial content. Honest, boring reporting doesn't get clicks, scary exaggerated content does. His latest video is no exception to this.
Something to consider
