As state officials emphasized the danger of continued increases in COVID-19 cases during a Friday press conference, they also outlined their plans for how the first supplies of COVID vaccine expected to arrive this month would be used.  Oregon Health Authority Director Patrick Allen said over 147-thousand first doses of vaccines, fairly evenly divided between the Pfizer and Moderna vaccines, will arrive by December 22.  Allen emphasized front-line health care workers will be prioritized to receive the first doses, along with first responders, workers in long-term care facilities and congregate care settings, and long-term care facility residents.  Allen said guidelines for prioritizing the next phase 1 groups, including essential workers, adults with high-risk medical conditions, and those 65 and over, remain under development.  He also said they are setting up a state-wide “cold chain network” of locations to provide ultra-cold storage for the Pfizer vaccine.
