A claque of online anti-vaccine influencers and dissentient researchers are claiming that COVID-19 vaccines are causing an epidemic of aggressive, fast-spreading cancers. The theory, dubbed "turbo cancer," has gained traction despite a lack of credible evidence.
One of the more prominent promoters of this claim is British nurse educator and prolific YouTuber John Campbell. In a recent YouTube talk, Campbell claims, "There has been for some time now, from talking with various experts, about the increased risk of cancers, probably all types of cancer, or many types of cancers, after COVID vaccines." In the video, Campbell cites a recent Italian study as evidence for his assertions.
