HHS Nominee Sean Kaufman Questioned Infant Hepatitis B Vaccine and Autism Link in 2025 Posts

Kaufman’s deleted LinkedIn post and video explicitly tied rising autism diagnoses to the birth-dose hepatitis B vaccine, arguing transmission risks are limited to adult behaviors. CDC surveillance data show perinatal transmission rates of 70-90 percent without prophylaxis, reduced to under 1 percent with timely vaccination. His comments align with RFK Jr.’s broader critique of universal recommendations while contradicting ACIP policy that has driven a 90 percent drop in new U.S. pediatric infections since 1991.

Confirmation hearings before Sen. Cassidy will test whether Kaufman’s biosafety background overrides his public statements on mRNA and recombinant platforms. Cassidy previously opposed delaying the hepatitis B birth dose, citing his hepatology practice. Kaufman’s role would include oversight of the Strategic National Stockpile, creating potential friction over future countermeasure procurement if vaccine safety reviews are reopened.

Observational data from Denmark’s 657,461-child cohort and the U.S. Vaccine Safety Datalink continue to find no elevated autism risk after hepatitis B vaccination. Next steps require the nominee to clarify whether he accepts these findings or intends to commission new studies before altering stockpiling or distribution protocols.
