Madonna has had quite the career.But the queen of pop’s latest reinvention came this week in the form of a video posted on Instagram that shared a coronavirus conspiracy theory with her 15 million followers.Madonna claimed a vaccine existed but was being concealed. “They would rather let fear control the people and let the rich get richer and the poor get poorer,” she said.Instagram blurred the video, captioned it “false information” and linked users to a page debunking the bogus claim.
