The University of Arizona is encouraging students to get vaccinated before they travel outside of Pima County and, ideally, students should receive their first dose by Friday to be fully vaccinated come summer vacation, UA President Robert C. Robbins said on Monday morning. âWe want to vaccinate as many of our students as we can, prior to the end of the semester, with many students traveling out of state to return home for the summer, or to do programs outside of Pima County,â said Robbins. âWe have a very limited window to administer the first dose for them to reach full vaccination before traveling, due to the wait time between doses.â
