IN THE COURT OF APPEALS OF THE STATE OF WASHINGTON

MICHELLE ZIMMERMAN, No. 87629-5-I

Appellant,

v. DIVISION ONE

KING COUNTY, WASHINGTON and DOW CONSTANTINE in his official UNPUBLISHED OPINION capacity as King County Executive, the CITY OF SEATTLE, a municipal corporation and BRUCE HARRELL in his official capacity as the Mayor of the City of Seattle, the department of PUBLIC HEALTH - SEATTLE & KING COUNTY and FAISAL KHAN in his official capacity as Director of Public Health - Seattle & King County, and DOES 1 through 100, inclusive,

Respondents.

CHUNG, J. — Michelle Zimmerman was injected with the Janssen – Johnson & Johnson COVID-19 vaccine (“Janssen Vaccine” or “J&J Vaccine”) on March 14, 2021, by the Department of Public Health – Seattle & King County (DPH). 1 After receiving the vaccine, she experienced adverse reactions. She then filed suit against King County, 2 the city of Seattle (City), and Mayor Bruce Harrell, alleging a variety of claims, including that they were negligent, failed to

obtain her informed consent, made intentional and negligent misrepresentations and omissions, and failed to follow the accepted standard of care. She sought declaratory and injunctive relief as well as a writ of mandamus. King County moved to dismiss under CR 12(b)(6), asserting immunity under the “Public Readiness and Emergency Preparedness Act,” 42 U.S.C. § 247d, et seq. (PREP Act). The City and Mayor Harrell also moved to dismiss under CR 12(b)(6), asserting they were improper parties to the suit, as King County fully administered DPH. The trial court granted both motions. We affirm the trial court’s order granting King County’s motion to dismiss all claims for loss, because the PREP Act provides immunity against such claims. We also conclude that Zimmerman has not established the elements for a writ of mandamus and, therefore, we affirm the dismissal of the petition for writ. Finally, we affirm the trial court’s order to dismiss the City on all claims for the same reasons and, separately, affirm the dismissal of Mayor Harrell as a party because he was sued solely in his official capacity.

BACKGROUND 3

Since January 1981, the City and King County have “operate[d] . . . a combined City and county health department . . . known as the [department of] ‘Public Health—Seattle & King County.’ ” Seattle Municipal Code (SMC) § 3.30.010. In March 2021, DPH owned and operated the Kent ShoWare Center

3 As this is an appeal of a motion to dismiss, the facts as alleged in Zimmerman’s

complaint are accepted as true. Rodriguez v. Loudeye Corp., 144 Wn. App. 709, 717, 189 P.3d 168 (2008) (citing Tenore v. AT & T Wireless Servs., 136 Wn.2d 322, 329-30, 962 P.2d 104 (1998)) (at motion to dismiss stage, “[a]ll facts alleged in the plaintiff’s complaint are presumed true”).

vaccination clinic where Michelle Zimmerman received the Janssen Vaccine. Zimmerman alleges that “[w]ithin minutes of being injected,” she experienced an acute anaphylactic reaction to the vaccine that caused her throat and tongue to swell and a shooting pain down her vaccinated left arm up through her neck to her left ear. She claims her left wrist dropped to the point where she could not move it. Zimmerman stayed at the clinic for observation and “was sent home after an hour.”

After she returned home, the swelling took over three hours to subside.

Further, “she experienced a racing heart and rapid breathing and became unresponsive,” and she had a fever of 104.8 degrees, which lasted for nine more days. Her symptoms worsened, and by the end of April 2021, she had developed left-sided weakness, speech problems, and vestibular problems; experienced memory loss; lost consciousness; and lost her ability to walk or talk for periods of time. Zimmerman alleges that “[s]he has been fully disabled ever since.”

On February 27, 2024, Zimmerman filed a “Complaint for Damages and Petition for Writ of Mandate [sic] Upon Affidavit” against King County, the City, and Mayor Harrell (collectively, “Defendants”). Her claims against all named Defendants are predicated solely on actions of DPH. Zimmerman alleges that DPH failed to comply with public health requirements when it allegedly failed to keep records, provide her with essential disclosures and safety information, warn her about possible dangers and side-effects, and report adverse events, including failing to timely report adverse events to the “Vaccine Adverse Events Reporting System” (VAERS), and by misrepresenting to her that it filed a VAERS

report regarding her adverse event. Zimmerman also alleges that DPH made four other material misrepresentations by telling her the following:

(a) the [Janssen] Vaccine was approved (as opposed to authorized only for emergency use) by the FDA, (b) the [Janssen] Vaccine was safe and effective, (c) other vaccines were not accessible, and (d) she would not be allowed to continue teaching in person classes at Renton Prep unless she accepted the [Janssen] Vaccine by the end of March 2021.

(Emphasis omitted.) Zimmerman asserts that she would have refused the vaccine “[b]ut for the Health Care Providers’ material misrepresentations, omissions, and failure to provide Ms. Zimmerman with the required information,” and the vaccine “has caused a cascade of neurological reactions incapacitating her and destroying her career and ability to conduct normal life functions.”

Based on those allegations, Zimmerman brought claims of negligence and gross negligence; intentional and negligent misrepresentations and omissions and concealment; failure to secure informed consent; and failure to comply with the standard of care. Zimmerman requested declaratory and injunctive relief, including a declaration that “Defendant’s practices have violated, and will continue to violate, without limitation, substantive and procedural directives of the applicable statutory law” as well as a permanent injunction enjoining Defendants from further administering any COVID-19 vaccines . . . without acting in compliance with . . . all public health guidelines.”

Zimmerman also sought orders that would require Defendants to provide certain information and to disgorge Defendants’ “unjustly acquired revenue,” and that would also impose a constructive trust upon Defendants. In addition, Zimmerman requested restitution, special damages, pre- and post-judgment

interest “as allowable,” exemplary or punitive damages, attorneys’ fees, litigation expenses, and other damages or “further relief” available under the law or “as equity and justice may require.” Finally, Zimmerman petitioned for mandamus, seeking to compel Defendants to “complete and submit a true and accurate VAERS report with the [Department of Health and Human Services]” and “provide Petitioner and other persons similarly situated with the information and disclosures . . . mandated by the Secretary’s Declaration, the CDC, FDA, and other mandatory public health guidelines.”

King County moved to dismiss, asserting immunity from liability under the PREP Act. The City asserted that it and Mayor Harrell were improper parties to the lawsuit, as DPH is administered wholly by King County and Zimmerman alleged no personal actions by Mayor Harrell outside his official capacity. The superior court agreed with both King County and the City and separately granted both motions to dismiss. This appeal followed.
