Spread of delta variant underscores importance of COVID vaccine

About 60% of eligible adults in Pima County are fully vaccinated against the disease.

This week Pima County rescinded its COVID-19 emergency resolution that the board of supervisors enacted in March of last year. It comes as county health officials announced that 70% of eligible, adult residents have received at least one dose of the vaccine. But for those who remain unvaccinated, including children, the so-called delta variant presents a threat as it becomes the dominant strain across the United States. We discussed the risks with University of Arizona epidemiologist Michael Worobey.
