On Immunity

The first story I ever heard about immunity was told to me by my father, a doctor, when I was very young. It was the myth of Achilles, whose mother tried to make him immortal. She burned away his mortality with fire, in one telling of the story, and Achilles was left impervious to injury everywhere except his heel, where a poisoned arrow would eventually wound and kill him. In another telling, the infant Achilles was immersed in the River Styx, the river that divides the world from the underworld. His mother held her baby by his heel to dip him in the water, leaving, again, one fatal vulnerability.

When Rubens painted the life of Achilles, the River Styx is where he began. Bats fly across the sky of that painting and the dead ride a ferry in the distance. Achilles dangles from his mother’s hand by one plump leg, with his head and shoulders entirely underwater. This is clearly no ordinary bath. The three-headed hound who guards the underworld lies curled at the base of the painting where the baby’s body meets the river, as if the baby is being plunged into the beast. Conferring immunity, the painting suggests, is a perilous task.

To prepare her children for the hazards of life, my own mother read Grimms’ fairy tales aloud to us every night before bed. I do not remember the brutality for which those tales are famous as vividly as I remember their magic—the golden pears growing in the castle garden, the boy no bigger than a thumb, the twelve brothers who became twelve swans. But it did not escape my notice, as a child, that the parents in those tales have a maddening habit of getting tricked into making bad gambles with their children’s lives.

In one story, a man agrees to trade with the devil whatever is standing beyond his mill. He thinks he is giving away his apple tree, but to his dismay he finds his daughter standing beyond the mill. In another story, a woman who has been longing for a child becomes pregnant and craves a plant called Rapunzel that grows in the garden of a wicked enchantress. The woman sends her husband to steal the plant and when he is caught, he promises their future child to the enchantress, who locks the girl away in a tall tower with no door. But maidens locked in towers will let down their hair.

And so it was in the Greek myths my mother read to me later. A king who had heard an ominous prophecy could not keep his daughter childless by locking her in a tower. Zeus visited her in the form of a shower of gold that left her pregnant with a child who later killed the king. When the infant Oedipus, left on a mountainside to die, was saved by a shepherd, he was not saved from the prophecy that foretold he would kill his father and marry his mother. And Thetis, Achilles’s mother, could neither burn nor drown his mortality.

A child cannot be kept from his fate, though this does not stop the gods themselves from trying. Achilles’s mother, a goddess who married a mortal, heard a prophecy that her son would die young. She made every effort to defy this prophecy, including dressing Achilles as a girl during the Trojan War. After he took up a sword and was discovered to be a boy, his mother asked the god of fire to make a shield for him. This shield was emblazoned with the sun and moon, the earth and ocean, cities at war and peace, fields plowed and reaped—the universe, with all its dualities, was Achilles’s shield.

The story my father told me when I was young was not the myth of Achilles, he reminds me now, but another ancient story. As my father relates the plot, I understand why I confused the two. The hero of this story is made immune to injury by bathing in the blood of a dragon. But a leaf clings to his body while he bathes, leaving a small spot on his back where he is unprotected. After having been victorious in many battles, he is killed by one blow to that spot.

Immunity is a myth, these stories suggest, and no mortal can ever be made invulnerable. The truth of this was much easier for me to grasp before I became a mother. My son’s birth brought with it an exaggerated sense of both my own power and my own powerlessness. I found myself bargaining with fate so frequently that my husband and I made a game of it, asking each other what disease we would give our child for prevention against another—a parody of the impossible decisions of parenthood.

When my son was an infant, I would hear many variations of “All that matters is that he is safe.” I would wonder whether that was, indeed, all that mattered nearly as often as I would wonder if I could keep him safe. I was certain that I did not have the power to protect him from his fate, whatever it might be. But I was determined nonetheless to avoid the bad gambles of the Grimms’ tales. I would not let my child be cursed by my own carelessness or cupidity. I would not accidentally say to the devil, You may have what is beyond the mill, only to discover that what is standing beyond the mill is my child.

In this bold, fascinating book, Eula Biss addresses a chronic condition of fear – fear of the government, the medical establishment, and what may be in your children’s air, food, mattresses, medicines, and vaccines. Reflecting on her own experience as a new mother, Biss investigates the metaphors and myths surrounding our conception of immunity and its implications for the individual and the social body. She extends a conversation with other mothers to meditations on Voltaire’s Candide, Bram Stoker’s Dracula, Rachel Carson’s Silent Spring, Susan Sontag’s AIDS and Its Metaphors, and beyond. On Immunity is an inoculation against our fear and a moving account of how we are all interconnected – our bodies and our fates.

‘Sontag said she wrote Illness as Metaphor to “calm the imagination, not to incite it,” and On Immunity also seeks to cool and console. But where Sontag was imperious, Biss is stealthy. She advances from all sides, like a chess player, drawing on science, myth, literature to herd us to the only logical end, to vaccinate.’
— Parul Sehgal, The New York Times

New Yorker

On Immunity is brave because it will attract hostility from those she implies are selfish or misguided in refusing to vaccinate. Her arguments are profoundly compelling, and her narratives are braided together with beauty and elegance. The book is itself an inoculation – it grafts and unites different traditions of the essay, and in doing so creates something stronger and more resilient. And its urgent message is an inoculation against ignorance and fearmongering: may it spread out through the world, bringing substance and common sense to the vaccination debate.’ 
— Gavin Francis, Guardian

On Immunity explores the controversy over vaccinations in the United States; yet this description fails to capture the book’s beauty, breadth, nuance, and timeliness. Amid insightful disquisitions on a host of topics, Biss relates her experiences as a first-time mother negotiating a series of health crises her son faced in his early years and her evolving thoughts about immunizations. But what makes this book so vital right now is its discussion of the ideas and issues we have all become conversant with since this awful year began: herd immunity, viral transmission, and our role as citizens in what Biss refers to at different times as immunity’s “public space,” its “garden.”’
Matthew Davis, Los Angeles Review of Books

‘On Immunity is as political as it is personal – Biss rails against a capitalism that has made unnatural individuals of us all – and as philosophical as it is political. ... What Biss does best, however, is doubt. She develops arguments and amasses detail but she also allows her writing to be shot through with uncertainty. Not often does a writer baldly admit that they don’t know what something means (in this case, the ending of Candide). It is a very human non-fiction that emerges, comfortable with its questions.’
—  Sophie Elmhirst, Financial Times

‘The primary malady Biss confronts is fear. Weaving fluidly between cultural touchstones that express our preoccupation with bodily contamination (Bram Stoker’s Dracula, Rachel Carson’s Silent Spring), Biss subtly builds a case for surpassing it. She addresses and debunks outdated but common concerns... On Immunity advances a compelling central thesis: “We owe each other our bodies.” Through her discussion of immunity and vaccination, Biss posits that our individual health is inextricably linked to the collective health of our communities and that we must act accordingly.’
Paloma Pacheco, The Tyee

‘Imagine Eula Biss as herself a vaccine against vague and incoherent thinking, as a booster to the acuity of your thought, as a thermometer taking the temperature of our ideas about purity, contagion, individuality, and community. This book is a magnificent piece of research and of writing.’ 
— Rebecca Solnit, author of Wanderlust: A History of Walking

‘Like so many great nonfiction classics, On Immunity will teach, provoke, chafe, inspire, haunt, and likely change its many readers. Its central, difficult, and ecstatic premise – that “we owe each other our bodies” – couldn’t be more urgent, as the question of how we contend with this interdependence, this collectivity, is fundamental to our human present and future.’
— Maggie Nelson, author of The Argonauts

‘Eula Biss accomplishes two remarkable things in this book. She efficiently dismantles the wall between self-documentation and world-documentation. And she synthesizes a vast amount of information into the haunting and inescapable conclusion that “we are ... continuous with everything here on earth, including – and especially – each other.”’
— Sarah Manguso, author of The Guardians: An Elegy

On Immunity ... weaves metaphor and myth, science and sociology, philosophy and politics into a tapestry rich with insight and intelligence.’
— Jerome Groopman, The New York Review of Books

‘A philosophical look at the history and practice of vaccination that reads like Joan Didion at her best. If you are yourself a nonfiction author, your initial response to this book might be to decide immediately on another line of work; Biss is that intimidatingly talented ... This is cultural commentary at its highest level, a searching examination of the most profound issues of health, identity and the tensions between individual parenting decisions and society.’ 
— The Washington Post

‘An elegant, intelligent and very beautiful book, which occupies a space between research and reflection, investigating our attitudes toward immunity and inoculation through a personal and cultural lens.’ 
— Los Angeles Times 

‘I was happy to have found an essayist of striking originality, a writer able to dissect difficult issues with poetic skill informed by personal insight and powerful research.’
Ian Birrell, i

‘Biss eloquently dismantles the myths of self-reliance and individualism that underlie anti-vaccine conspiracy theories.’
Sophie Murguia, Outside Magazine
