Our KGW VERIFY team set out to answer some frequently asked questions about the COVID-19 vaccine. Author: Rebecca Coster, Hanna Merzbach Published: 6:01 PM CST December 3, 2020 Updated: 3:12 PM CST December 31, 2020 PORTLAND, Oregon — Ready and available vaccines for COVID-19 are here and have been administered to healthcare workers in Oregon and Washington. The biopharmaceutical companies Pfizer and Moderna both recently announced that their coronavirus vaccines have around 95% efficacy. The Pfizer vaccine is being distributed nationwide after it gained emergency use authorization from the U.S. Food and Drug Administration (FDA). Moderna will go through the same FDA review process this week. As these vaccines are being produced in record time, and much is still unknown about their long-term effects, many questions remain unanswered.
