(Portland, OR) -- Oregon health officials are reporting low rates of flu vaccinations among health care workers. Newly released data shows just 64-percent of health care workers in Oregon were vaccinated against the flu last year. The Oregon Health Authority wants that to be near 90-percent. Hospitals had the highest rate at 69-percent, followed by ambulatory surgery centers, nursing facilities, inpatient psychiatric and dialysis facilities. The pandemic and a lack of reporting might be causing the low number.
