SALEM â Eastern Oregon lawmakers are seeking data that has long remained out of Umatilla Countyâs grasp in a move to correct the countyâs COVID-19 vaccination rate. In a letter to Gov. Kate Brownâs office last week, lawmakers noted many Umatilla County residents have been vaccinated by Washington health care providers and veteran health services in Walla Walla. Others were vaccinated on the Confederated Tribes of the Umatilla Indian Reservation at mass vaccine clinics with the Oregon National Guard, which reports its data to the U.S. Centers for Disease Control and Prevention, officials say. Much of that data has yet to be reported to the state, officials say, which has âunfairly impactedâ the countyâs progress toward reopening as it remains among the lowest ranked counties statewide for vaccinations per capita.
