Updated December 13, 2020 Oregon officials expect the state to receive its first batch of COVID-19 vaccines from Pfizer on Tuesday, Dec. 15. And by the end of the month, Oregon expects to receive 228,400 doses—assuming the Moderna vaccine is also approved by the U.S. Food and Drug Administration for emergency use. Both the Pfizer and Moderna vaccines require two doses, so at least some of the doses will be for a second round of vaccination. The federal government has issued guidance for who should get priority in receiving COVID-19 vaccinations. It recommends the first doses go to hospital workers, both medical and nonmedical, as well as emergency medical services workers who "regularly evaluate, treat, and transport potential COVID-19 patients," and nursing homes, both residents and staff.
