On April 12, in an auditorium at the University of Michigan, “amid fanfare and drama far more typical of a Hollywood premiere than a medical meeting” (according to The New York Times), Dr. Thomas Francis announced the results of an investigation into the polio vaccine developed by a former student of his, Dr. Jonas Salk. The verdict: Salk’s vaccine worked. The 150 journalists in the audience rushed off to file their stories, and, by the next morning, thousands of doses of vaccine were on their way to children across America. Just as quickly, Salk was on his way to becoming a scientific celebrity.
The announcement did not come as a surprise. Early results from clinical trials had been promising, leading drug manufacturers to prepare for production more than a year ahead of time. By the date of the announcement (the tenth anniversary of the death of President Franklin D. Roosevelt, a polio patient), 27 million doses had been stockpiled in warehouses around the country.
