There is little agreement among experts as to how employers should think about religious exemptions for the COVID vaccine—or whether employers even have to offer exemptions in the first place.

Does it matter if the requester has the backing of a major religious institution? Does it matter if that institution publicly supports the vaccine and opposes exemptions? How do you judge if a request is in good faith when there is an entire industry built around helping people falsely claim religious objections? Where do you draw the line for something as complex and personal as faith?
