Investigation and Verification Process
Since its founding over 164 years ago, the Sanctuary of Our Lady of Lourdes has recorded more than 7,000 claims of healing. The Lourdes Office of Medical Observations (OMO) conducts decade-long investigations, requiring extensive documentation and follow-up. “We [are] looking for a diagnosis and if that diagnosis is a diagnosis of a severe disease with a severe prognosis,” — Dr. de Franciscis, a former pediatrician and Harvard trained epidemiologist
Recent Recognitions
In 2022, the OMO announced two additional cures, raising the total number of officially recognized miracles to 72. The most recent cases join earlier recognitions such as Vittorio Micheli’s recovery from osteosarcoma (1960s), Sister Luigina Traverso’s reversal of near-total paralysis (mid-1960s), Delizia Cirolli’s vanished knee tumor (1970s), and Sister Bernadette Moriau’s cure of cauda equina (2000s). All four individuals reported being healthy when revisited by 60 Minutes in 2022.
Expert Assessment of the OMO’s Rigor
Dr. Esther Sternberg, research director at the University of Arizona’s Andrew Weil Center for Integrative Medicine, evaluated the OMO’s records in a 2014 study. She concluded that the office’s determinations were “credible” and reflected the best possible analysis given available data. “As medical science and rigor in diagnosis progressed…determining whether something was an unexplained cure progressed as well,” — Dr. “They [Lourdes Office of Medical Observations] kept adding these different layers of evaluation…and more diagnostic measures. And then following them up for a longer time.” — Dr. Sternberg
Impact on Pilgrimage and Skepticism
Each year, roughly four million pilgrims travel to Lourdes, many hoping for miraculous healing. While skeptics argue that early investigations lacked modern rigor, the OMO’s evolving standards aim to address those concerns. No independent study has disproven the office’s conclusions, though the scientific community remains divided over the interpretation of “unexplained” cures.
Ongoing Documentation
The 60 Minutes segment featuring correspondent Bill Whitaker and OMO president Dr. Alessandro de Franciscis was first broadcast in a video released on December 18, 2022. The segment continues to shape public understanding of how the sanctuary balances faith-based claims with contemporary medical scrutiny.
