If you're not anti-vax then it's because you haven't done enough research, period. I'm sorry to be so blunt, but my whole life (I'm 54) I thought anti-vaxxers were nut-job conspiracy theorists... until I actually stopped assuming that what we've been taught our whole lives is the truth, and started looking into the subject after a friend's perfectly healthy three month old baby died from the vax he received at his "well baby" (ironic name) checkup. Turns out that SIDS (Sudden Infant Death Syndrome) is actually caused by the Tdap vax. SIDS is even listed as a side-effect on the pamphlet that comes in the box with the vax vial.
