Last US iron lung patient's legacy warns of polio's dangers amid vaccine hesitancy

Martha Lillard, paralyzed by polio at age 5, spent 73 years dependent on an iron lung before dying at 78; her case exemplifies polio's lifelong disabling impact on survivors.
One year between Martha's life and a different life entirely

With the death of Martha Lillard at 78, the United States has lost its last living witness to a particular kind of medical captivity — a woman who spent 73 years breathing with the help of a machine because a vaccine arrived one year too late for her. Her passing arrives at a moment of troubling irony: the very disease her iron lung held at bay is being reconsidered as a voluntary concern by public health officials, even as the collective memory of its devastation quietly dissolves. History, when forgotten, does not stay quiet — it waits.

  • Martha Lillard, paralyzed by polio at five years old, died on June 26 after 73 years of life inside an iron lung — the last of her kind in America.
  • Her death coincides with a dangerous shift in public health posture: a CDC advisory chair has suggested making the polio vaccine optional, citing improved sanitation and changed conditions.
  • Vaccine hesitancy is rising across the country, and Lillard's sister fears that younger generations, having never witnessed polio's devastation, are dangerously close to inviting it back.
  • Polio was eliminated in the US by 1979 through mass vaccination — a hard-won victory now at risk of being quietly surrendered through complacency and institutional doubt.
  • McVey's grief is inseparable from her warning: the disease disfigures, disables, and traps — and the only thing standing between the present and the 1950s is a vaccine people are beginning to question.

Martha Lillard died on June 26 at 78, the last known polio patient in the United States still dependent on an iron lung. She had contracted the disease at five years old in the mid-1950s — just one year before a vaccine became available — and spent the rest of her life encased in the metal cylinder that breathed for her.

Yet her younger sister, Cindy McVey, remembers her not as a prisoner of the machine but as someone who refused its limitations. Lillard learned to drive, using a family-modified vehicle with the steering wheel in her lap. She painted landscapes. She kept dogs. Her uncle and grandfather built a device that let her enter and exit the iron lung independently. She lived alone. "She could do things most iron lung patients couldn't do," McVey said.

Polio, at its peak in the 1950s, was a disease of mass terror. The WHO estimates that one in 200 infections leads to irreversible paralysis; of those, between five and ten percent die when the virus reaches the breathing muscles. Tens of thousands of Americans once relied on iron lungs to survive. The nationwide vaccination campaign that followed the 1955 vaccine eliminated the disease from the US entirely by 1979.

Now, more than four decades later, that achievement is under quiet threat. Kirk Milhoan, chair of the CDC's Advisory Committee on Immunization Practices, has suggested the polio vaccine should become optional, arguing that times have changed. McVey heard those words and felt dread. She watched her sister die — from post-polio syndrome, chronic pulmonary failure, and what she believes was a final blow from long Covid-19 — and saw in that death a warning going unheeded.

"They may think there's problems with the vaccine," McVey said, "but there's a whole lot more problems if they don't vaccinate." Her fear is simple and specific: a generation has grown up in a world without polio, and may not understand what it means to lose that world.

Martha Lillard died on June 26 at the age of 78, marking the end of an extraordinary life spent almost entirely tethered to a machine. She was the last known polio patient in the United States still using an iron lung—a hulking metal cylinder that had kept her alive for 73 years, ever since she contracted polio at five years old in the mid-1950s.

The iron lung worked through a simple, relentless principle: a motor-driven bellows created a vacuum around the patient's body, forcing the lungs to expand and draw in air. When the pressure reversed, the lungs deflated. For most of her waking hours, Lillard's body was encased in this device. Yet her younger sister, Cindy McVey, remembers her not as someone defeated by it, but as someone who refused to be confined by it. Lillard learned to drive—her family retrofitted a vehicle so the steering wheel sat in her lap, the turn signals positioned on the floor within reach. She painted detailed landscapes. She kept beagles. She lived alone, thanks to a contraption her uncle and grandfather built that allowed her to enter and exit the iron lung on her own terms. "She could do things most iron lung patients couldn't do," McVey said.

When Lillard woke up that morning in the mid-1950s unable to lift her head from the pillow, she already knew what had happened. Polio was the terror of the age. Children feared it. Parents feared it. At five years old, Lillard had heard enough about the disease to recognize it in her own body. She spent time in physical therapy, occupational therapy, water therapy—fighting to keep whatever strength remained. She regained partial use of her left arm and the use of her legs. The paralysis that defined her life could have been total.

Polio in those years was catastrophic. According to the World Health Organization, one in 200 polio infections results in irreversible paralysis. Among those paralyzed, between 5 and 10 percent die when the virus immobilizes their breathing muscles. Tens of thousands of Americans relied on iron lungs to survive. The disease had peaked in the 1950s, killing and maiming children across the country.

Then came the vaccine. In 1955, a polio vaccine became available. A nationwide vaccination campaign followed. By 1979, polio was declared eliminated in the United States—no longer spreading routinely through the population. The disease that had once filled hospitals and homes with dread was gone. Lillard had gotten polio the year before the vaccine arrived. "I had a friend who got to test that vaccine the year Martha got polio," McVey said. "It was that close."

Now, more than four decades after polio's elimination in America, vaccine hesitancy is rising. Earlier this year, Kirk Milhoan, chair of the Advisory Committee on Immunization Practices at the Centers for Disease Control and Prevention, suggested that polio vaccines should become optional. He argued that conditions have changed since the 1950s—sanitation is better, disease risk is different, and the calculus of vaccination should shift accordingly. "We need to not be afraid to consider that we are in a different time now than we were then," he said.

McVey listened to that rhetoric and felt fear. She watched her sister die—officially from post-polio syndrome and chronic pulmonary failure, though she attributes the final blow to long Covid-19—and she saw in that death a warning that no one seemed to be heeding. "Polio is terrible," she said, tears in her eyes. "The disease disfigures, disables and leaves people trapped. We had it under control here and now we have all these people who aren't vaccinating their children." She worries that the memory of polio has faded too far. A generation has grown up knowing only a world without it. They may doubt the vaccine. They may believe the risks outweigh the benefits. But they have never seen what polio actually does. They have never watched someone spend 73 years in an iron lung. "They may think there's problems with the vaccine, but there's a whole lot more problems if they don't vaccinate," McVey said.

What strikes you most about Martha's life—was it the restrictions, or the way she moved past them?

Model

The restrictions were real and constant. But Martha didn't accept them as a definition. Her family understood that too. They didn't just accept the iron lung; they engineered around it. That's what I keep thinking about—the ingenuity born from necessity.

Inventor

Her sister mentioned she was an artist, an intellectual. Did polio take those things from her?

Model

No. That's the point. Polio took her mobility, her independence in the physical sense. But it didn't take her mind or her will. She painted landscapes. She asked her Alexa device endless questions. She had a partner she loved for more than twenty years. The disease didn't erase her.

Inventor

But it did define her life in a way most of us will never understand.

Model

Absolutely. Seventy-three years in that machine. That's not a life lived despite polio—it's a life lived with polio as the constant condition. And now her sister is watching people dismiss the vaccine that could have prevented all of it.

Inventor

Do you think people understand how close we came to losing polio entirely?

Model

We did lose it. In America, anyway. That's the tragedy of what's happening now. We won. We eliminated it through vaccination. And now, because we won, people think the threat isn't real anymore. They've never seen what it does.

Inventor

Martha got polio one year before the vaccine existed.

Model

One year. Her sister had a friend who tested that vaccine the same year Martha got sick. One year between Martha's life and a different life entirely. That proximity—that's what should haunt us.
