Zoom in: Montana has made it illegal to "discriminate" on the basis of vaccine status, with some exceptions within the health care sector. The law prohibits businesses, governmental entities and places of "public accommodation" — like grocery stores, hotels or restaurants — from refusing to serve or withholding goods from anyone based on their vaccination status or whether they have an "immunity passport."... Alabama law, for example, prevents schools and universities from requiring coronavirus vaccines, prohibits vaccination as a condition of receiving government services, and bans businesses from refusing to serve someone based on their vaccine status. Several other states have implemented measures that are targeted more narrowly to state and local governments or schools.
