RFK Jr.’s Miasma Theory of Health Is Spreading

Last week, the two top officials at the National Institutes of Health—the world’s largest public funder of biomedical research—debuted a new plan to help Americans weather the next pandemic: getting everyone to eat better and exercise.

The standard pandemic-preparedness playbook “has failed catastrophically,” NIH Director Jay Bhattacharya and NIH Principal Deputy Director Matthew J. Memoli wrote in City Journal, a magazine and website published by the Manhattan Institute for Policy Research, a conservative think tank. The pair argue that finding and studying pathogens that could cause outbreaks, then stockpiling vaccines against them, is a waste of money.
