Pediatric Immunizations at a Glance

Keep your child healthy during their most important times of growth and development by staying on track with their exams and their immunization schedule. The American Academy of Pediatrics—a professional organization of primary care pediatricians dedicated to the health, safety, and well-being of infants, children, and young adults—has recommended an immunization schedule based on age. Research has shown the schedule to be the safest and most effective way of protecting children from disease.

At TrueCare, we put you and your family’s health first.

If you’re uncertain about which immunizations are due, feel free to give us a call. We are here to help! We’ve broken down, by age group, the different immunizations recommended for children.
