Our office will continue to follow the American Academy of Pediatrics recommended vaccine schedule, newly updated for 2026. The schedule has been endorsed by 12 top medical and health organizations. We follow the science and the schedule that has been designed for our country and our population. Feel free to talk to your child's pediatrician about the recent changes by the CDC and why they don't actually make sense for our children.
