At least six states — Arkansas, Florida, Montana, Oklahoma, Tennessee and Utah — have enacted legislation to limit Covid shot mandates, giving vaccine opponents some of their most prominent victories in recent memory. At least 11 states have banned the use of vaccine passports, according to the National Council of State Legislatures, and another 31 states at minimum are considering similar legislation... The anti-vaccine movement saw an opportunity at the pandemic’s onset to bring more people into the fold by shifting its message from the shots themselves to governments’ often-unpopular promotion of masks and social distancing, said Erica DeWald, director of strategic communications and partnerships at Vaccinate Your Family, a vaccine education group co-founded by former first lady Rosalynn Carter. “This is the first time that they’ve been able to attach themselves to an issue that has successfully passed,” she said.
