evidence: Content shared on Facebook claims the BBC has said that HIV is used to make the Covid-19 vaccines. [...] All this is explained in the BBC documentary. However, some claims shared on social media only clip the segment where Professor Chappell talks about developing the vaccine using an HIV protein, not the later segments where it is explained the vaccine was abandoned. The vaccine was never rolled out beyond the original trial participants, and the vaccines currently in use in the UK do not contain any material from HIV.
