A Facebook post includes a video taken from a Fox News broadcast of several Americans discussing health conditions that had developed after having a Covid-19 vaccine.
While the original broadcast is real, a logo in the top right of the screen for PolitiFact, a US fact checking organisation, has been added without consent.
A representative of PolitiFact told Full Fact “We did not authorize the use of the PolitiFact logo in that video, and in no way do we vouch for the comments made in the video.
“It appears someone maliciously posted the PolitiFact logo on that video in order to give it added credibility.”
