Katelyn Jetelina
Your Local Epidemiologist — CDC and outbreak-data translator
Epidemiologist behind Your Local Epidemiologist, which translates CDC policy, vaccine recommendations, and outbreak data for 390,000+ subscribers (her Substack footer), with 500M+ views across 130+ countries per her bios. A former CDC/White House senior scientific advisor, now at the Yale School of Public Health, and a TIME100 Health honoree.
Coverage status — October 2026: Jetelina publishes the flagship “The Dose” roundups plus state editions (NY, CA), translating CDC policy and outbreak data for a general audience. In 2026 she joined the Governors Public Health Alliance — a state-level counterweight to federal CDC policy — as an advisor; she is still an independent writer, but no longer a pure outsider to the fight she covers.
Her stance toward the Kennedy administration is critical and evidence-first. Her March 10, 2026 Dose quantified the harm she attributed to a White House Tylenol briefing for pregnant patients, and she has steered readers to the AAP’s HealthyChildren.org as, in her assessment, CDC guidance lost credibility under Kennedy.
Her documentation method is data work: she builds posts on CDC datasets she annotates herself and on peer-reviewed studies, showing the numbers rather than summarizing other people’s coverage. Her background — former CDC/White House senior scientific advisor, now at the Yale School of Public Health — means her criticism comes from inside the institutions she translates.
Why tracked here: she owns the CDC-data beat — the most-read independent translation of what the agency’s numbers actually say, written from a critical stance toward the current administration.
