evidence: A recent Belgian study on coronavirus vaccines has been read by millions of people after it was shared on social media by anti-vax campaigners. The anti-vaxxers claim that the study shows that there is a link between coronavirus vaccines and so-called "turbo cancer", a phenonium that is not recognised by scientists. However, one of the scientists that worked on the research Sander Eens says that the study proved no such thing. "There is not a single piece of scientific evidence, neither in our study nor elsewhere that points to there being a causal link between mRNA-vaccines and cancer. [...] Nevertheless, prominent antivaxxers such as the controversial Canadian doctor William Makis shared the Belgian scientists’ work on what was then still Twitter. Dr Makis has often spread fake news about coronavirus vaccines in the past. Dr Makis claimed that the study "proves that mRNA vaccines cause turbo cancer". "Turbo cancer" is a term that has been doing the rounds for some time now among anti-vaxxers. It implies that coronavirus vaccines cause fast-growing tumors or cancers. However, to date there is no scientific evidence to back this up.
