How Can Theatremakers Be Partners in Public Health? Just Ask Eureka Day

Jonathan Spector’s play Eureka Day stands as a poignant example of how theatremakers can help society collectively understand and engage with one of the most polarizing public health issues of our time: vaccination. As the world continues to struggle with vaccine hesitancy, misinformation, and distrust in public health institutions, theatre provides an essential medium for breaking through philosophical divides.

Theatre as a Public Health Conversation

Set within the ideologically charged environment of a progressive private school in Berkeley, California, Eureka Day dissects the difficulties of consensus-building in a fractured society. The central conflict unfolds as a mumps outbreak sweeps through the fictional Eureka Day School, forcing its governing board to confront the implications of their previously laissez-faire vaccination policies. As the crisis escalates, the school’s attempts to mediate between pro- and anti-vaccine parents devolve into chaos. Directed by Anna D. Shapiro, the recent Manhattan Theatre Club production brilliantly blends biting humor with profound humanity, making it essential viewing for both theatre artists and public health leaders navigating the complexities of science communication.

Vaccination remains a lightning rod in contemporary discourse, emblematic of broader cultural tensions surrounding bodily autonomy and community responsibility. In Eureka Day, Spector to expose the hypocrisies and contradictions that arise when individuals attempt to reconcile personal freedom with the collective good. The play primarily satirizes the affluent, progressive elite—people who see themselves as enlightened, inclusive, and open-minded but struggle when their values are tested by real-world conflicts. In the play’s opening scene, the school board agonizes over whether to add “transracial adoptee” to a dropdown menu—an act of inclusivity so microscopic that it borders on self-parody. Yet when confronted with a life-or-death health crisis, these same individuals are incapacitated by their commitment to consensus, revealing a dangerous gap between idealistic rhetoric and practical governance. Several characters embody contemporary liberal anxieties:

• Suzanne, a privileged mother who opposes vaccines, relies on personal anecdotes and alternative medicine rhetoric while insisting she is “not anti-science.”
• Don, the school’s affable principal, prioritizes harmony over taking decisive action, exposing the ineffectiveness of conflict-avoidant leadership
• Meiko, a single mom and nervous knitter, highlights how progressive spaces can tokenize diversity while failing to address real structural issues

Spector also employs absurdity, irony, and exaggerated dialogue to highlight the disconnect between progressive ideals and real-world consequences. As the school grapples with the outbreak, a livestreamed parent meeting becomes one of the play’s most effective and unsettling sequences. Here, Spector captures the anarchy of online discourse as reasoned debate collapses into trolling, personal attacks, and escalating emoji warfare. The scene brilliantly dramatizes how social media amplifies misinformation, erodes nuance, and rewards the loudest, most extreme voices. It is a moment of sharp comedic absurdity that highlights the dangers of a fragmented and hyper-polarized information ecosystem.

In Eureka Day, Spector to expose the hypocrisies and contradictions that arise when individuals attempt to reconcile personal freedom with the collective good.

The Limits of Rational Persuasion

One of Eureka Day’s most compelling contributions to public health discourse is its acknowledgment that facts alone are insufficient to change minds. While empirical evidence overwhelmingly supports the safety and efficacy of vaccines, psychological research has shown that people often reject information that contradicts their deeply held beliefs—a phenomenon known as the backfire effect. When individuals feel that their identity or values are under threat, we are more likely to double down on existing positions rather than reconsider them. The play circumvents this effect in several ways:

The Mumps Outbreak as a Narrative Device

The central crisis—a mumps outbreak—grounds the debate in a tangible public health reality. Unlike abstract ideological arguments, this outbreak forces characters to confront the direct impact of unvaccinated children in their community. The play illustrates how herd immunity works (or fails) in a school setting, implicitly reinforcing the necessity of vaccination without relying on direct exposition.

Personal Stories are used as Data Points

The character of Suzanne represents a familiar type in vaccine discourse—someone who rejects mainstream medicine and justifies her stance with personal anecdotes rather than scientific consensus. Rather than simply caricaturing her, the play reveals that her hesitancy stems from personal trauma and distrust in institutions. This reflects real-world research on why people reject vaccines—not out of simple ignorance, but often due to medical mistrust, fear, or past experiences. Vaccine-hesitant audience members who saw the play have remarked on feeling that their perspectives were represented authentically.

Similarly, Carina, a new parent and the most pragmatic board member, serves as a voice of reason, often pointing to the greater good and public health realities when others remain indecisive. Her position subtly integrates scientific reasoning into the conversation.

Another character, Eli, a young tech bro whose own child falls ill, offers a large donation to the school contingent on the board enforcing a vaccination policy. This underscores themes of power, influence, and the complexity of ethical decision-making in the context of public health.

Public Discourse and Misinformation

The chaotic livestreamed parent meeting is a brilliant dramatization of how misinformation spreads. As parents’ comments flood in, arguments spiral from genuine concerns to conspiracy theories, cherry-picked statistics, and emotional appeals, mimicking the way social media can be used to distort scientific facts leading to greater polarization. By staging this dynamic, the play demonstrates the barriers to effective public health communication in an era of digital misinformation.

The Play’s Implicit Verdict

While the play allows space for empathy toward vaccine-hesitant parents, the ultimate trajectory of the story—where disease spreads due to low vaccination rates—reinforces scientific consensus. Unlike a purely "both sides" narrative, Eureka Day aligns with the evidence-based reality that vaccines prevent outbreaks and protect communities.

Expanding the Role of Theatremakers in Public Health

Theatre engages audiences emotionally and personally in ways that traditional public health campaigns often cannot. Unlike messaging that leans heavily on statistics and expert testimonials, theatre embraces ambiguity, nuance, and discomfort—qualities frequently absent in media coverage of vaccine debates. Eureka Day exemplifies this power by refusing to “solve” the issue of vaccine hesitancy. Instead, it offers a space for audiences to sit with its complexities, contradictions, and human dimensions.

One reason this is effective is because of “neural coupling”—a phenomenon where the brain activity of a speaker and a listener (or performer and audience) becomes synchronized during effective communication or shared experiences. Our brains react to the characters and events on stage as if we are personally living through them. As artists and scientists have affirmed, theatres are gymnasiums for empathy—spaces where we temporarily agree to suspend not only disbelief but also prejudice, enabling different points of view to play out without our unconscious censors shutting them down.

When theatremakers translate complex health information into emotionally engaging stories, they may run the risk of oversimplification, but when the balance is right, they can make abstract topics like vaccination, mental health, or climate-related illness more accessible and relatable. In addition to health communication, theatre can challenge stereotypes and correct misinformation through character-driven narratives and the inclusion of lived experiences and other data points, thereby promoting empathy around stigmatized health issues.

By using humor to address vaccine hesitancy, the play sidesteps defensiveness and encourages a more open engagement with the topic.

According to a recent World Health Organization (WHO) report on the evidence base for the role of the arts in improving health, theatremaking and theatregoing can be understood as health behaviors. Just like brushing your teeth, eating well, exercising, getting enough sleep and spending time in nature, participating in the viewing or making of theatre activates psychological, physical, social, and behavioral responses that can lead to positive health outcomes.

For example, theatre offers a communal space for processing difficult issues and imagining new possibilities for healthier, more equitable societies. A theatre ensemble devising work may, where invited with suitable facilitation, channel their own concerns and anxieties about specific health issues into tangible characters and storylines. Theatre audiences experience the story collectively, engaging in a form of private yet shared contemplation, which can reduce isolation and catalyze further conversation. In my own research, this proved to be true even with virtual performances presented to audiences who were able to interact online. 

The laughter that Eureka Day provokes is itself a powerful public health tool. Humor has been shown to reduce resistance to challenging information, making audiences more receptive to new perspectives. By using humor to address vaccine hesitancy, the play sidesteps defensiveness and encourages a more open engagement with the topic.

Finally, to truly expand the role of theatremakers in public health, we need to create opportunities for greater collaboration between theatre artists and institutions, the communities they serve, health providers, and public health leaders. As with any good public health strategy, we also need repetition over time through a variety of media. Eureka Day is a play that, like a vaccine, should be disseminated widely to increase our collective capacity to respond to future health crises.

In a time when trust in science (and our neighbors) is increasingly fragile, we must explore new ways to engage the public in meaningful discussions about health.

Why Eureka Day Matters

As public health debates continue to be hijacked by political polarization, Eureka Day reminds us of the power of theatre to present the possibility of co-existence. Jonathan Spector’s play does not offer easy solutions, nor does it seek to shame or vilify. Instead, it challenges us to listen, to laugh, and to see the humanity in those with whom we disagree. Instead of delivering didactic lessons, it embeds public health evidence into character arcs, humor, and social satire, making the consequences of misinformation and inaction unmistakable. This elevates the play beyond a simple debate—it becomes an exploration of how scientific truth collides with human psychology, privilege, and ideology in real-life decision-making.

In a time when trust in science (and our neighbors) is increasingly fragile, we must explore new ways to engage the public in meaningful discussions about health. Theatre, with its unique ability to blend entertainment, dissent, and empathy, has an essential role to play in this effort. By supporting works like Eureka Day, we can ensure that the arts remain not just a source of enrichment, but a vital partner in public health.

Coda

The play’s themes resonate even more sharply against the backdrop of today’s political climate. As the nation grapples with the presidency of Donald Trump and his controversial pick of Robert F. Kennedy, Jr. as Secretary of the United States Department of Health and Human Services, health experts fear the consequences of mainstreaming vaccine skepticism. Kennedy’s well-documented history of spreading misinformation about vaccines has reignited anxieties about declining immunization rates, the resurgence of preventable diseases (like measles), and the erosion of trust in medical institutions. Although Eureka Day was conceived before these political developments, its narrative uncannily reflects the dilemmas now dominating public discourse. Its cancellation from the Kennedy Center following Trump’s takeover as chairman of the theatre’s board, combined with changes to National Endowment for the Arts grant guidelines, raises questions about the prospects of realizing and sustaining the ideas presented in this essay.
