Summary

On Day 672 of the Plague, virologist Lisa Michael waits alone in her Toronto office at the University of Toronto for the final results of her vaccine trial. She has spent 657 days on the project, and the anticipation is almost unbearable. A previous attempt failed three months earlier when several test chimpanzees died, but since then she isolated the female chromosome that was resisting the vaccine and believes the new formulation will work.

As she waits, Lisa reflects on her lab's composition. Of the fourteen virology postgraduate students and postdoctoral scientists working with her in November 2025, thirteen were women. The lone man, Jeremy, has since died. Lisa deliberately prioritized hiring women throughout her career, a policy she defends against accusations that she favored diversity over ability. She argues that the scientific world has deep-seated sexism, and that the preponderance of male-dominated virology labs proved disastrous when the Plague struck. She also believes her team's relative emotional distance from the virus—most of them are not fighting for their own lives—gives them a crucial advantage. Male scientists, desperate to save themselves, could not do their best work; calm, dogged persistence, she insists, is what wins scientific races.

Wendy, Lisa's deputy, bursts into the office in tears with the news: one hundred percent survival, blood tests all clean. The vaccine works. Lisa's initial reaction is restrained; she knows the hard work is just beginning. She reflects that the world will call the vaccine a miracle, but she knows it is the product of hard work, dedication, and ingenuity.

Lisa then calls the Canadian Public Health Agency. She insists the official address her as Dr. Michael, not by her first name. She announces that she has a vaccine with a one hundred percent success rate and clean blood tests, and that she has bypassed the missing chromosomes. Then she delivers her startling demand: she intends to sell the vaccine to Canada rather than provide it freely. She requests a meeting and warns the agency not to attempt stealing the vaccine from her lab. The official protests that she would never do such a thing, but Lisa laughs, certain she would.

Key Events

Final vaccine trial results confirm 100% survival and clean blood tests.
Lisa reflects on her all-female lab and the death of her male colleague Jeremy.
Lisa calls the Canadian Public Health Agency and announces her breakthrough.
She insists on being addressed as Dr. Michael, asserting her professional authority.
Lisa declares she will sell the vaccine to Canada, not give it away.
She warns the agency against attempting to steal the vaccine.

Character Development

Lisa Michael emerges here as a figure of immense competence and steely pragmatism. Her confidence borders on arrogance—she compares herself to a god on the phone—but it is grounded in years of preparation and deliberate team-building. Her decision to sell the vaccine reveals a calculating, commercially minded side that has not been fully visible before. She has apparently planned this move for months, discussing it with Margot. Her insistence on being called Dr. Michael underscores her refusal to be diminished or patronized, especially by government officials who might underestimate her.

Wendy, Lisa's deputy, provides the emotional counterpoint. She bursts in crying, hoping for a shared celebration, but Lisa quickly redirects her to the next task. Wendy's loyalty and competence are clear, even as Lisa's demanding management style is acknowledged.

Margot is referenced but does not appear. Lisa mentions the bottle of Dom Pérignon they saved and notes that Margot urged her to confront the Plague months ago. Margot is clearly Lisa's closest confidante, the one person with whom she has discussed her plan to sell the vaccine.

Ashley, a former colleague who compiled early reports on the Plague, is mentioned briefly. She no longer works with Lisa, and her earlier sadness about the Plague stands in contrast to Lisa's more clinical fascination.

Themes, Symbols, or Motifs

Sexism in science and women's leadership. Lisa's reflections on the scientific establishment's ingrained sexism are central. She argues that her policy of hiring the best female applicant produced a team that was better equipped to survive the Plague and develop a vaccine. The chapter suggests that institutional bias left male-dominated labs vulnerable when the crisis hit.

Commercialization vs. public good. Lisa's decision to sell the vaccine rather than donate it introduces a major ethical tension. She frames it as a business transaction, not an act of charity, and her warning against theft implies she expects the government to try to seize it.

Miracles vs. hard work. Lisa explicitly rejects the language of miracles. The vaccine, she insists, is the result of years of training, preparation, and relentless testing. This theme reinforces the novel's broader argument that survival depends on competence and foresight, not luck.

Desperation vs. calm persistence. Lisa argues that the best science emerges from calm, logical persistence, not desperation. Male scientists fighting for their own lives were too emotionally compromised to do their best work. This is a pointed and somewhat controversial claim that the chapter presents as Lisa's firm belief.

Animal testing and its costs. The chapter notes that 253 chimpanzees died during testing. Lisa's dark humor about reducing her monkey kill count highlights the moral weight of scientific progress.

Why This Chapter Matters

This is a pivotal turning point in the novel. The vaccine—the thing the entire world has been waiting for—is finally achieved, and Lisa Michael is the one who did it. The chapter establishes her as the central figure in the race to end the Plague and sets up the major conflict to come: whether the vaccine will be shared freely or sold for profit. Lisa's decision to commercialize the vaccine introduces a tension between individual agency and collective survival that will likely drive the next phase of the story. The chapter also crystallizes the novel's themes around gender, competence, and the ethics of scientific discovery.

Study Questions and Answers

1. Why does Lisa insist on selling the vaccine to Canada rather than providing it freely?

Lisa has planned this move for months and discussed it with Margot. She frames the vaccine as her achievement and her property, not a public good. Her decision reflects her pragmatic, transactional worldview and her distrust of government institutions. She also seems to relish the power reversal—after years of being underestimated as a woman in science, she now holds something the government desperately needs and can dictate terms.

2. How does Lisa's all-female lab contribute to her success?

Lisa argues that her deliberate hiring of the best female applicants created a team that was both highly competent and less personally vulnerable to the Plague. Most of her scientists were not fighting for their own lives, which she believes allowed them to work with calm, logical persistence rather than desperation. She also notes that she began training virologists years before the Plague, giving her lab a head start.

3. What does Lisa mean when she says the vaccine is not a miracle?

Lisa rejects the language of miracles because she believes it diminishes the years of hard work, training, and dedication that produced the vaccine. Miracles, she says, are easy; working is hard. Her insistence on this distinction reflects her broader worldview: survival depends on preparation and competence, not luck or divine intervention.
