What the 2026 Schedule Covers

The core vaccines on the 2026 schedule include DTaP (diphtheria, tetanus, and pertussis), MMR (measles, mumps, and rubella), varicella (chickenpox), IPV (polio), Hepatitis A, Hepatitis B, and meningococcal vaccines for older kids and adolescents. The schedule also includes the annual flu vaccine, which the AAP recommends for all children 6 months and older — with the goal of getting vaccinated before the end of October.

It's worth noting that Hepatitis A requires two doses spaced 6-18 months apart, and some vaccines in the DTaP series require boosters at specific ages. If your child has gaps in their records or recently moved to COS from another state or country, it's worth asking your pediatrician to do a full catch-up review.

How to Check Your Child's Records in Colorado

Colorado maintains the Colorado Immunization Information System (CIIS), a statewide registry where pediatricians log immunizations. You can request a copy of your child's immunization history through your pediatrician's office, and most Colorado providers can access the CIIS record in minutes.

If you've recently moved to Colorado Springs, your previous provider can share records, or your new pediatrician can enroll your child in CIIS and build their record from documentation you bring in.

What's Next

The single best action: call your child's pediatrician this week and ask them to run a quick immunization review. It takes minutes and can head off a compliance issue with D11, D20, or D49 later in the semester. The fall flu vaccine window is also open — the AAP recommends all kids get their annual flu shot by the end of October, so pairing the records check with a flu vaccine appointment is a practical way to get both done in one visit.
