So over the last 50 years, vaccines are estimated to have saved 154 million lives worldwide. I support vaccines. I'm a doctor. Vaccines work. Secretary Kennedy, in your confirmation hearings, you promised to uphold the highest standards for vaccines. Since then, I've grown deeply concerned. The public has seen measles outbreaks; leadership of the National Institute of Health questioning the use of mRNA vaccines; the recently confirmed director of Centers for Disease Control and Prevention fired. Americans don't know who to rely on.
