We're talking about Washington, a one-party state with extreme left politics. This is how it actually works:
Vaccinated person goes to the hospital for a cough and fever - "oh no dear, it can't be COVID because you're vaccinated, it must be the common flu" - not counted.
Unvaccinated person comes in for a wrist sprain, tests positive on the PCR - "OMG UNVAXXED HOSPITALIZATION" - probably counted twice, too.
