(Portland, OR) -- Oregon health officials are reporting another hiccup in the flow of COVID-19 vaccines from the federal government. Oregon Health Authority Director Patrick Allen says they've learned the next shipment of vaccines will be smaller than expected. There will be 30-percent fewer doses of the Pfizer vaccine and seven-thousand fewer doses of the Moderna vaccine. Allen says they need to be prepared for the shipments to change depending on the federal government's shipment schedule.
