Fifteen (15) states have prohibited proof-of-vaccination requirements at all or some levels of government: Alabama, Alaska, Arizona, Arkansas, Florida, Georgia, Idaho, Indiana, Iowa, Montana, South Carolina, South Dakota, Texas, Utah, and Wyoming.
In 10 of those states, governors banned proof-of-vaccination requirements through executive orders. In the other five, legislators passed laws banning proof-of-vaccination requirements.
Additionally, five states have gone a step further. Alabama, Iowa, Montana, Texas, and Florida have extended bans on proof-of-vaccination requirements to some private businesses.
On the other hand liberal socialist leaning states, New York, Hawaii, and Oregon exempt fully-vaccinated individuals from some COVID-19 restrictions. To avoid the restrictions, they must provide proof of vaccination.
