Your editorial “Vinay Prasad’s Vaccine Kill Shot” (Review & Outlook, Feb. 12) points out that a recent decision by Mr. Prasad, the leader of the Food and Drug Administration’s vaccine division, will have negative consequences.
Mr. Prasad’s decision to reject Moderna’s flu vaccine without even reviewing it is even worse than you describe. Denying us a new, innovative flu vaccine is horrible health policy. Innovation is at risk because, as Moderna’s CEO has said, if the largest market is off limits, investments won’t be made.
But the decision will also have economic consequences. Investment in preventive health is critical as our population ages. In its April 2025 World Economic Outlook report, the International Monetary Fund dedicated an entire chapter to the need for healthier longevity as the global population ages.
