“...these massive vaccines that are twice the size of a jar like that, of a glass of water like that, I mean, into a baby's body.”

A standard infant vaccine dose is at most 0.5 milliliter, roughly one-tenth of a teaspoon, while two glasses of water run about 480 to 950 milliliters. Trump's claim overstates the real volume by a factor of roughly 1,000 to 2,000. The dose injected into a baby's arm is a tiny fraction of a teaspoon, not a 'vat' or anything resembling a glass of water. These volumes are not estimates; they are printed in every FDA-approved vaccine package insert and are publicly verifiable. The CDC and pediatric infectious-disease experts confirm that infants tolerate these microliter-scale injections without difficulty. University of Maryland pediatrician Dr. James Campbell described the infant dose bluntly: 'It's tiny, and babies tolerate it perfectly fine.' Trump made this 'two glasses of water' claim at the same October 9, 2025 Cabinet meeting where he also falsely asserted babies get 82 vaccines in a single shot. CNN's fact-checkers flagged both statements as false, part of a string of vaccine misinformation in the same appearance. No infant has ever been injected with hundreds of milliliters of vaccine.
