Across Utah, the number of adults fully immunized against the coronavirus is approaching 1 in 3, putting the state just above national averages. More than 70% of seniors statewide have been vaccinated. But some rural counties are lagging far behind, according to state data obtained by The Salt Lake Tribune, with fewer than half of their seniors fully inoculated — even though they have been eligible for weeks, and Utahns age 70 and up have been eligible since mid-January. Health officials chalk up the disparities to both challenges in accessing vaccine and less interest.
