In Northern California, the pastor of a megachurch hands out religious exemption forms to the faithful. A New Mexico state senator will "help you articulate a religious exemption" by pointing to the decades-old use of aborted fetal cells in the development of some vaccines. And a Texas-based evangelist offers exemption letters to anyone -- for a suggested "donation" starting at $25. With workplace vaccine mandates in the offing, opponents are turning to a tried-and-true recourse for avoiding a covid-19 shot: the claim that vaccination interferes with religious beliefs.
