Maryanne Demasi
Investigative journalist (MD Reports) — FDA/CDC vaccine-regulation documents
Maryanne Demasi is an Australian investigative journalist (PhD; formerly ABC Catalyst) whose MD Reports works from FDA and CDC primary documents — trial data, internal emails, and agency dockets. She supports Kennedy's vaccine-skeptical direction while also attacking the administration from the MAHA flank when she judges it to have surrendered ground.
Coverage status — October 2026: Demasi was active through Oct. 6, 2026, publishing MD Reports (and pieces via the Brownstone Institute). Although she is based in Australia, her beat is overwhelmingly the US agencies. Her audience size is not publicly disclosed.
Her documentation is unusually primary-source-driven for the supportive camp: she filed a formal public comment on HHS docket No. HHS–OS–2026–0332 (submitted Sept. 19, 2026), works from trial data, internal NIH emails, and released documents, and on July 30, 2026 mined Sen. Rand Paul’s 1,141-page release of Fauci’s diary.
Her stance is supportive of Kennedy’s vaccine-skeptical direction — and willing to attack the administration from the MAHA flank. In September 2026 she broke the story that CDC had quietly reinstated COVID vaccine recommendations for infants, which her camp called a “staggering surrender,” and on Sept. 8, 2026 she charged that the FDA’s review of Moderna’s flu mRNA vaccine was “botched.”
Why tracked here: she is the vaccine-regulation beat’s document hound on the movement side — the writer most likely to surface an agency paper trail before anyone else, whichever direction it cuts.
