Newly appointed FDA leaders exhibit an ideological "dualism" by promoting unproven therapies like bone marrow stem cells while showing deep skepticism towards vaccines with robust safety data. This signals a concerning shift where regulatory decisions may be driven more by ideology than by rigorous biomedical science, creating uncertainty across the industry.

The decision to block Moderna's application was made personally by CBER Director Dr. Vinay Prasad, against the recommendation of the FDA's vaccine office staff. This unusual top-down intervention bypasses standard scientific review processes, raising concerns about politicization and the integrity of the regulatory process.

The CDC's recent decision to remove six pediatric vaccines from its recommended list without input from its advisory committee (ACIP) signals a potential shift in public health governance. This move may sideline traditional scientific bodies, creating a vacuum that other groups, like the American Pediatric Association, are trying to fill.

Moderna spent $1 billion on a trial based on FDA guidance that was later deemed unacceptable. This arbitrary "changing of the rules" after the fact makes long-term, capital-intensive investment in new medicines like vaccines extremely risky for pharmaceutical companies.

The FDA's "refuse to file" decision is highly unusual, occurring in only 4% of cases and typically for incomplete or flawed applications. Using it to block Moderna's submission over a previously-agreed-upon trial comparator suggests a strategic shift in regulatory posture, not a simple procedural issue.

The revamped CDC advisory panel (ACIP) is not seeking to ban vaccines outright. Instead, its strategy is to use purported safety concerns to sow public doubt and introduce "regulatory friction." This approach creates confusion and barriers to access, which can be just as effective at reducing vaccination rates as an outright ban.

The FDA is shifting policy to no longer allow reliance on immunogenicity data (immunobridging) for approving new or updated vaccines. This move toward requiring full clinical efficacy trials will make it harder to combat evolving pathogens and would have prevented past approvals of key vaccines like those for HPV and Ebola.

Moderna's trial used a standard-dose comparator, the same design basis on which the FDA previously approved two other enhanced flu vaccines for seniors. The agency's refusal to review Moderna's data ignores its own scientific and regulatory precedent, suggesting the application of a new, unstated standard.

Following its decision, FDA officials appeared on news channels and made pointed comments, including suggesting Moderna show "humility." This public relations offensive is unusual for a regulatory agency and serves as a warning to the industry, reflecting a newly adversarial relationship with developers.
