"I've been trying to shout it from the rooftops," to get parents to take their kids in for routine vaccines, says Dr. Sean O'Leary, professor of pediatrics at the University of Colorado School of Medicine and vice chair of the Committee on Infectious Diseases for the American Academy of Pediatrics. Many parents worry about COVID-19 and when they can vaccinate their kids against it, O'Leary notes. But he says, "Frankly, a lot of the diseases that we vaccinate kids for are more severe in children than COVID, and so the last thing we want as we reenter the school year is outbreaks of these other vaccine-preventable diseases."
