(KOLD News 13) - The University of Arizona COVID-19 state vaccination site moved into its next phase and is now vaccinating people 55 and older by appointment only. U of A students can expect to enter a new stage this month as well. âIf they feel as though weâre prepared to go into that stage then I completely agree,â senior at the U of A, Kyra Lozow said. âPlus, Iâve been waiting to go back to in-person classes so hopefully some of mine will start being in-person, and I think that theyâll continue to monitor it and make sure that students are getting tested and doing what weâre supposed to be doing.â
