As a physician, my task is to keep people safe and as healthy as possible. Medicines, including vaccines, play a big role in this undertaking. However, almost equally dangerous as viral spread is the spread of false hope. To pacify expectations, I often turn to my public health colleague, Irwin Redlener, MD, director of the National Center for Disaster Preparedness, Columbia University: “Suggestions that oral polio vaccine may have a role in temporarily preventing Covid-19 are provocative, but not really supported by the kind of evidence that would make many of us optimistic.” Dr. Redlener was surprised by Dr. Fauci’s public support of OPV. “It’s far too early to suggest that OPV is some kind of miraculous, low-cost preventive measure,” added the professor of pediatrics.
