Or: A tour of the pre-Prevnar wonderland where 5 million American kids a year got ear infections, 700 got meningitis, and the survivors mostly couldn’t hear you complain about it.
Welcome to “Remember When Kids Just Died?” A daily two-part tour through every vaccine-preventable disease, starting with polio on September 1, 2026. Each disease gets two posts: the pre-vaccine era, when parents enjoyed the character-building experience of burying their children, and the post-vaccine era, when we ruined everything by making childhood survivable. Cramming both into one post felt disrespectful, to the corpses and the Nobel Prizes.
The Bug That Was So Prolific It Got a Nickname
In 1892, Sir William Osler, Canadian physician, co-founder of Johns Hopkins, wrote about a disease that had climbed to the top of the American mortality charts. He called it, borrowing a phrase from a 1680 Puritan tract by John Bunyan, “the Captain of the Men of Death” (Cleveland Clinic Journal).
He was talking about pneumonia. And more than any other single organism, he was talking about pneumococcus. Osler also called pneumonia “the old man’s friend,” because it killed the elderly in “an acute, short, not often painful illness.” Nobody ever called pneumococcus “the toddler’s friend.” What it did to toddlers was industrial.
Streptococcus pneumoniae was first isolated in 1881, independently and simultaneously, by U.S. Army physician George Sternberg and French chemist Louis Pasteur. While the classifiers argued about who saw it first, the bug worked.
Pneumococcus, Now Live-Streaming From Your Child’s Body
Before the year 2000, in American children younger than 5, pneumococcus was responsible for, annually (CDC Pink Book): About 17,000 cases of invasive pneumococcal disease. Roughly 13,000 cases of bacteremia, bacteria loose in the bloodstream of a toddler who, an hour earlier, was fine. Approximately 700 cases of pneumococcal meningitis. About 200 dead children under 5. Around 5 million cases of acute otitis media every year. More than 10 million pediatrician visits for middle-ear disease.
By age 12 months, more than 60% of American children had already had at least one ear infection. Infants under one had the highest pneumococcal meningitis rates of any age group, about 10 per 100,000. Pneumococcus alone caused more than half of all bacterial meningitis in the United States. This was not the exotic tail of pediatrics. This was Tuesday.
The Pre-Antibiotic Meningitis Numbers Are Genuinely Difficult to Read
Modern parents have the historical luxury of never having read the pre-antibiotic pediatric meningitis literature. It is bracing. Before sulfa drugs arrived in the late 1930s, pneumococcal meningitis mortality was, in the words of the Journal of the Pediatric Infectious Diseases Society, “approaching 100%” (JPIDS, 2015). Not rhetorical. Actual.
The historical case series read like grocery lists of dead children: New Orleans, 1936: 1 survivor out of 111 patients. Cleveland, 1922–1938: 0 survivors out of 157. Boston City Hospital, 1929–1937: 0 survivors out of 125. Boston Children’s Hospital, pre-1939: 1 survivor out of 74. Toronto: 0 survivors out of 121 children.
These were the flagship pediatric hospitals of the industrialized world. Their pneumococcal meningitis wards were, functionally, hospice. Sulfa cut overall mortality to about 33%, but mortality in children under 2 remained stuck at 100% even after sulfa arrived. Every baby died. Every time. Penicillin helped, but Robert Austrian famously showed that patients kept dying in the first 96 hours of treatment no matter how aggressively you dosed them. The bug was faster than the drug.
The Survivors, Because This Story Gets Worse
Say your child survived pneumococcal meningitis. There was a 25% to 33% chance they were about to be permanently damaged: neurologic sequelae in 20–40% of survivors, hearing loss in 14–35%, plus cerebral palsy type deficits, seizure disorders, hydrocephalus, and cognitive impairment in various miserable combinations (Frontiers in Neurology, 2020). Pneumococcus remains, to this day, the single most common bacterial cause of acquired sensorineural deafness in children. It doesn’t just kill kids. It quietly takes their hearing on the way out.
The Ear-Infection Industrial Complex
While pneumococcal meningitis was earning its ICU reputation, plain-old pneumococcal ear infections were building the entire mid-century pediatric practice model. Five million cases a year, ten million office visits, oceans of amoxicillin. Ruptured eardrums. Chronic middle ear effusions producing conductive hearing loss during the exact window when kids are supposed to be learning to talk.
Mastoiditis, infection burrowing into the bone behind the ear, sometimes requiring a surgeon to scoop out infected material. Then came the tympanostomy tubes: millions of toddlers under general anesthesia getting plastic grommets installed in their eardrums, repeat every 6–12 months as needed. In the 1990s, this was just… childhood.
The Antibiotic-Resistance Chapter, Because Of Course
By the 1970s and 1990s, the “just prescribe more penicillin” era ran into a wall: pneumococci that no longer cared. Then macrolide-resistant. Then multi-drug-resistant strains. By 2015, an estimated 30% of the 30,000 annual invasive pneumococcal cases in the U.S. were resistant to one or more antibiotics. The idea that we could “just treat pneumococcus” has been aging poorly since 1975. You can’t develop resistance to not being infected in the first place.
The Ledger
Add it up. In the pre-vaccine era, pneumococcus in American children under 5 was causing 17,000 invasive cases a year, 700 meningitis cases, 200 deaths, 5 million ear infections, 10 million pediatrician visits, enough mastoidectomies to keep a subspecialty in business, and a rising tide of antibiotic resistance quietly nullifying the one tool we had.
Zoom out further. In 1939, before penicillin and long before Prevnar, 24,637 American children under 15 died of pneumonia, pneumococcus being the leading bacterial cause (NEJM, 2000). Twenty-four thousand. In one year. In this country.
The Moral
The “good old days” of pneumococcus were not good. They were a slow, wet, coughing horror show, punctuated by the small white coffins that used to be a normal part of American life. Osler called pneumonia the Captain of the Men of Death because in 1892 that was a literal, quantitative description, not a metaphor. The kids who survived were, disproportionately, deaf.
Every American pediatrician practicing before 2000 has, somewhere in their memory, a specific dead toddler and a specific set of parents. Ask one. They will remember the name.
Next time someone tells you “kids used to just get these things and be fine,” send them the New Orleans series. One survivor out of 111. That was fine. That was normal. That is what “before the vaccine” actually looked like in an American children’s hospital in living memory.
Then send them the number for their pediatrician and book the Prevnar.
