AAP 2026 Vaccine Schedule Recommends More Shots Than CDC — What Colorado Families Should Know

If you've had a pediatrician's appointment lately and felt like you were getting different answers about which vaccines your child needs, there's a reason for that. The American Academy of Pediatrics and the CDC are no longer recommending the same immunization schedule for children — and the gap between the two lists has real implications for families in Colorado.

What the AAP Is Recommending

The American Academy of Pediatrics released its 2026 immunization schedule covering vaccines for 17 diseases. It's a comprehensive list that the AAP developed with input from 12 major national health organizations, and it's the schedule used by the majority of board-certified pediatricians across the country.

Among the vaccines the AAP schedule includes: hepatitis A, hepatitis B, meningococcal disease, rotavirus, flu, and RSV — as well as COVID-19 for children ages 6 to 23 months.

What the CDC Schedule Currently Covers

The CDC's 2026 schedule is shorter. It no longer recommends several vaccines that the AAP still includes — among them hepatitis A, hepatitis B, meningococcal disease, rotavirus, flu, and RSV. The total gap is roughly seven diseases where the two schedules diverge.

This kind of divergence between the AAP and CDC is unusual. Historically, the two organizations have aligned closely on immunization guidelines. The current split has created confusion for both families and some healthcare providers about which standard to follow.

Where Colorado Stands

Colorado's Department of Public Health and Environment (CDPHE) has come down clearly on the side of the AAP schedule. The agency is urging Colorado families and healthcare providers to follow the AAP's 2026 guidelines, not the CDC's. That position is consistent with 28 other states and 12 national health organizations that have endorsed the AAP schedule.

If your pediatrician is in Colorado, they're operating in a state where the public health authority has explicitly backed the more comprehensive list.

What to Ask at Your Child's Next Appointment

The simplest thing you can do is ask your child's doctor which schedule their practice follows and whether they've updated their recommendations for 2026. Most pediatricians who are members of the AAP will likely be following the AAP schedule, but it's worth confirming — especially if your child has a well-child visit coming up this fall.

If your doctor is following the CDC schedule, ask them why and whether they'd consider the AAP list given Colorado CDPHE's guidance.

What's Next

The AAP updates its immunization guidelines annually. The most current recommendations, along with a parent-friendly breakdown of the schedule, are available at healthychildren.org. Colorado-specific information is available through cdphe.colorado.gov under childhood immunizations.
