JRE #2462 - Aaron Siri · Aired Mar 3, 2026
Claim summary · not a verbatim quotation
The 2011 clinical trial for the Hepatitis B vaccine in infants was not placebo-controlled.
The finding
What the evidence shows
The general point about vaccine trials is stronger than this specific framing. Vaccine trials often compare against an existing vaccine rather than saline, because withholding protection from infants in a trial raises an ethics problem. That is a real design tradeoff worth arguing about, but the choice is made openly and for a stated reason, not hidden.
