OLYMPIA, Wash. –State health officials say the federal government has lowered COVID-19 vaccine supply allotments for Washington.

That’s apparently because of problems at a facility producing the Johnson & Johnson vaccine.

The Seattle Times reports comments about the decreased supply come as state officials prepare to open vaccine eligibility to everyone age 16 and over on April 15.

Health officials had expected the state to receive at least 600,000 doses of vaccine through state and federal programs for each week in April, but now Washington state expects deliveries of at least 500,000 doses next week.
