The CDC publishes a recommended immunization schedule for children from birth through age 18, covering the vaccines considered important for protecting against serious childhood diseases. Most pediatric offices and public health clinics in the U.S. follow this schedule.
What the Schedule Covers
Vaccines on the CDC schedule include hepatitis B, DTaP, polio (IPV), Hib, pneumococcal (PCV), rotavirus, MMR, varicella, hepatitis A, annual influenza, and RSV protection for infants, among others. Which vaccines a child needs at a given visit depends on their age and any doses already received.
Overview by Age
In the first six months, infants typically receive multiple rounds of hepatitis B, DTaP, Hib, polio, pneumococcal, and rotavirus vaccines, usually spaced around 2, 4, and 6 months. Around 12 to 15 months, MMR and varicella vaccines are typically introduced, and by ages 4 to 6, booster doses of DTaP, polio, and a second MMR dose tend to be recommended. An exact personal schedule is best confirmed with your child’s pediatric provider.
Before and After a Visit
Letting your care team know if your child currently has a fever or isn’t feeling like themselves can help decide whether to proceed or reschedule. Staying at the clinic for about 15 to 30 minutes after a vaccine is commonly recommended so any reaction can be observed early.
When to Seek Care Right Away
Persistent high fever, hives spreading across the body, or signs of a severe allergic reaction such as difficulty breathing or bluish lips call for emergency care right away. Significant swelling and warmth at the injection site along with unusual lethargy are also considered signs that call for prompt medical attention. This information is based on U.S. (CDC) guidance; if you live elsewhere, check with a local pediatric provider for country-specific recommendations.
