Survey describes vaccination coverage by age 2 years for US children born in 2021 and 2022

This is an observational survey report examining vaccination coverage by age 24 months among children born in the United States in 2021 and 2022. The study design is descriptive, with no comparator group or experimental intervention reported. The sample size and specific setting details are not provided in the available abstract.

The primary outcome was vaccination coverage by age 2 years. However, the main results, including specific coverage percentages, absolute numbers, effect sizes, and statistical measures (p-values or confidence intervals), are not reported in the abstract. The direction of any trends or changes in coverage is also not stated.

No safety, tolerability, or adverse event data are reported. Key limitations of the evidence are inherent to its observational, survey-based nature; it describes coverage patterns but cannot establish causality or the effects of vaccination itself. The funding sources and potential conflicts of interest are not reported.

For clinical practice, this report provides descriptive, population-level context. The lack of reported numerical results and the non-experimental design mean it cannot inform specific clinical decisions regarding vaccine efficacy or safety. Clinicians should seek the full report for detailed coverage rates and methodological context.
