The candidate vaccine uses technology that was largely abandoned in the 1970s. HHS Secretary Robert F. Kennedy Jr. shifted the money from a pandemic preparedness fund to a vaccine development program led by two scientists whom the administration recently named to senior positions at the NIH. While some experts were pleased that Kennedy had supported any vaccine project, they said the May 1 announcement contravened sound scientific policy, appeared arbitrary, and raised the kinds of questions about conflicts of interest that have dogged many of President Donald Trump’s actions.
Focusing vast resources on a single vaccine candidate “is a little like going to the Kentucky Derby and putting all your money on one horse,” said William Schaffner, MD, a Vanderbilt University professor and past president of the National Foundation for Infectious Diseases. “In science, we normally put money on a number of different horses because we can’t be entirely sure who’s going to win.”
