SEATTLE (AP) — Data from the Washington state Department of Health shows only a fraction of the more than 356,000 doses of the COVID-19 vaccine delivered here have been used. The Seattle Times reports that less than 20% of the distribution — 59,491 doses — had been administered as of Wednesday morning. The health department estimates that about 500,000 people qualify for vaccination in the top priority group, named 1A, which includes high-risk workers in health care, first responders and residents of long-term care facilities. To speed the pace of vaccination in some areas, the health department announced Wednesday  it was expanding the definition of the 1A category to allow extra vaccine to be distributed to health-care workers who are not on the front lines.
