Years before this year's anti-mask and reopening demonstrations, vaccine opponents were working on reinventing their image around a rallying cry of civil liberties and medical freedom. Now, boosted by the pandemic and the political climate, their rebranding is appealing to a different subset of society invested in civil liberties — and, some health officials say, undercutting public health efforts during a critical moment for vaccines.
