SEATTLE (AP) — Washington state health officials say the federal government has lowered vaccine-supply allotments for Washington, apparently because of problems at a facility producing Johnson & Johnson vaccine. The Seattle Times reports comments about the decreased supply Wednesday come as state health officials prepare to open vaccine eligibility on April 15 to everyone age 16 and over. 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. The federal government maintains the expected supply boost will come, but the timeline is not yet clear.
