Childhood Immunization Schedule

Children’s Health • Medically reviewed March 2023by the Cedarcrest Health clinical content committee

Vaccines protect children from a number of serious illnesses that were once common causes of childhood hospitalization and death. The recommended immunization schedule is designed to protect children at the ages when they are most vulnerable to specific diseases.

Why Timing Matters

Some vaccines require more than one dose to build full protection, which is why children receive a series of shots over their first years of life, with boosters at certain ages afterward. Following the recommended schedule helps ensure protection builds at the right time and stays current as children grow.

The schedule is reviewed regularly by national health authorities and adjusted based on ongoing research and disease patterns. Your child’s provider keeps track of what has been given and what is due at each well-child visit.

Tips for Keeping Track

• Keep a personal immunization record for each child and bring it to appointments.
• Ask your provider for a printed or electronic copy of the recommended schedule.
• Schedule well-child visits on time, since many vaccines are given during these checkups.
• Ask questions about any vaccine you are unsure about rather than skipping it.

Mild reactions such as soreness at the injection site or a low fever are common after vaccination and typically resolve within a day or two. Serious reactions are rare, and your child’s care team can talk through any concerns you have.

If you have questions about your child’s immunization schedule or need to catch up on missed vaccines, talk with your Cedarcrest Health primary care provider, or call (814) 555-2650 to schedule a well-child visit.
