With a reminder that Thursday marked a year since the first COVID test came back positive in Pima County and that more than 110,000 people have tested positive since then, Pima County Health Department Director Dr. Theresa Cullen said she is looking to the future as county officials expect to hit the goal of 300,000 vaccinations before the end of March. But whether they can reach that goal depends on how many vaccine doses arrive in Pima County from the state. As of March 4, 283,011 vaccines were administered in Pima County and Cullen said that if the county receives enough doses, it could hit the 300,000 mark sometime next week.
