OLYMPIA, Wash. — Washington state will launch a tool soon for the public to determine their own eligibility for the COVID-19 vaccination.

The state will rely on the honor system, launching an online self-reporting tool called PhaseFinder.

A spokesperson for the Department of Health told the Seattle Times that once more vaccination sites are available, members of the public could present screenshots of their results at vaccination sites.

The state also plans to provide a template letter for employers to vouch for workers’ eligibility.
