Covid: 'How a picture of my foot became anti-vaccine propaganda'

Patricia is suffering from an unexplained skin condition - but a misunderstanding about what might have caused it set off a chain of events that turned her foot into fodder for anti-vaccine activists. The picture showed purple and red sores, swollen and oozing with pus. 'Supposedly this is a [vaccine] trial participant,' read the message alongside it. 'Ready to roll up your sleeve?' Within a day, those same feet had been mentioned thousands of times on Instagram and Facebook. The picture went viral on Twitter as well.
