COVID vaccine mandates are proliferating -- and so, inevitably, are attempts to evade them by claiming a religious exemption. In Washington state, a church-affiliated group hosts "vaccine exemption workshops" for state employees, health workers, and school staff. On Facebook, people swap tips for couching vaccine hesitancy in religious terms. In Texas, employees are suing United Airlines over its policy of placing religious objectors on unpaid leave, one of many legal challenges to mandates around the country.
