Since the Covid vaccines were rolled out, a trend has sprung up – of accounts online linking virtually any death or illness, of a celebrity, athlete or ordinary person, to the shots without any evidence. A conspiracy theory film called Died Suddenly released last year appears to have supercharged this practice- termed “ghouling”. BBC Trending investigates how far the Died Suddenly film has spread and what its impact has been – on the people who believe its message, and on bereaved families being trolled. We speak to Stew Peters, the film-maker behind the film, and challenge him on the misleading claims he is spreading.
