Opinion

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KING COUNTY, WASHINGTON and DOW CONSTANTINE in his official UNPUBLISHED OPINION capacity as King County Executive, the CITY OF SEATTLE, a municipal corporation and BRUCE HARRELL in his official capacity as the Mayor of the City of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

1 We refer to DPH and Faisal Khan in his official capacity as director of DPH collectively

as DPH. 2 We refer to King County, Washington, and Dow Constantine in his official capacity as

King County Executive collectively as King County. No. 87629-5-I/2

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”).

2 No. 87629-5-I/3

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

3 No. 87629-5-I/4

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

4 No. 87629-5-I/5

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 . . .
