"This is bad policy, with no basis in public health," Ducey wrote in a series of tweets. "The vaccine works. But the vaccine is a choice. This policy is social engineering at its worst."
In a Monday statement, an ASU official said that as the college returns to in-person learning in the fall semester, all students enrolled in on-campus programs are expected to be fully vaccinated two weeks before Aug. 19, the first day of classes.
Students who are unable to be vaccinated for whatever reason or who don't agree to share their vaccination status will be required to undergo daily health checks, participate in twice weekly COVID-19 testing, and wear facial coverings in all ASU campus spaces—both indoor and outdoor.
Vaccinated students who provide proof of vaccination will not be subject to the above restrictions, though they—along with everyone else on campus—are encouraged to wear masks in crowded areas.
"As Sun Devils, we commit to being part of the ASU Community of Care where we take care of ourselves, each other and our community," Vice President of Student Services Joanne Vogel said in the statement.
