As a result, 40,000 developed "abortive" polio (a non-paralytic form of the disease), 56 were paralyzed, and five children died. Some of the vaccinated children also transmitted the virus, causing additional cases.The impact: This tragedy severely damaged public trust in the new polio vaccine. However, it also led to significant improvements in vaccine manufacturing standards and federal oversight through the Food and Drug Administration (FDA), preventing similar disasters in the future. Tetanus contamination (1901): In separate incidents, batches of diphtheria antitoxin and smallpox vaccine were contaminated with tetanus. This resulted in the deaths of 13 children in St. Louis, Missouri, and nine children in Camden, New Jersey. These events spurred the creation of the 1902 Biologics Control Act, the precursor to modern vaccine regulation.Swine flu vaccine and GBS (1976): Following a 1976 swine flu vaccination campaign in the US, an increased risk of Guillain-Barré Syndrome (GBS)—a rare neurological disorder—was observed. The vaccination program was halted, but a subsequent review concluded that the risk was small, at about one extra GBS case for every 100,000 people vaccinated.RotaShield and intussusception (1999): The first licensed rotavirus vaccine, RotaShield, was withdrawn from the market after it was linked to an increased risk of intussusception, a type of bowel obstruction, in infants. A safer vaccine was later developed and introduced.Fatal vaccination error in Samoa (2018): A deadly error occurred in Samoa where two children died after receiving an MMR vaccine that was improperly prepared with an expired muscle relaxant instead of the correct diluent. The accident led to a steep decline in vaccine confidence and a subsequent measles epidemic that killed dozens of children.
