FDA Vaccine Chief Calls for System "Rewrite" in Internal Memo

A top U.S. Food and Drug Administration (FDA) official has proposed a major overhaul of the nation's vaccine rules. The call for change comes from Dr. Vinay Prasad. He leads the FDA's Center for Biologics Evaluation and Research (CBER). This center is responsible for evaluating and approving all vaccines in the United States. An internal memo from Dr. Prasad suggests the current system needs rewriting. The details of the proposed changes are not public. However, such a move could affect how future vaccines are developed, tested, and approved. The memo signals that significant internal debate may be underway. Any rule changes would involve a lengthy official process with public input. The FDA has not yet commented on the memo or its specific proposals.
