The University of Nebraska-Lincoln is offering incentives to faculty, staff and students who voluntarily sign up for a registry showing they are vaccinated against COVID-19. The incentives include five prizes worth a total of $9,872 — equal to one year of in-state tuition and fees — or a trip to Ireland to watch the Huskers play football in August 2022. The university announced the initiative in a letter to students and staff on Wednesday. Anyone who registers by Aug. 15 will be eligible for the incentives. The university also announced it will again require weekly saliva-based testing for all students, faculty and staff on Lincoln campuses for the fall semester.
