CDC and AAP update 2023 immunization schedule for children and adolescents

The Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics (AAP) have published an updated immunization schedule for 2023. This guideline applies to children and adolescents aged 18 years or younger in the United States. The publication outlines recommended changes to the standard vaccination schedule, though the specific nature of these changes, the interventions or vaccines involved, and the comparator schedules are not reported in the provided summary.

No study type, phase, sample size, or follow-up duration is specified, as this is a formal recommendation document rather than a primary research study. Consequently, no primary or secondary outcomes, effect sizes, or statistical measures are presented. The guideline does not report on safety data, adverse events, or tolerability profiles for the updated schedule within this summary.

Key limitations include the absence of detailed evidence supporting the schedule changes and a lack of reported practice relevance statements. The funding sources and potential conflicts of interest for the guideline development are also not reported. For clinical practice, this update serves as an official directive. Healthcare providers should obtain and review the complete 2023 CDC/AAP immunization guideline document to understand the specific changes and implement them accordingly.
