Weekly Pediatric COVID-19 Vaccination Coverage and Parental Intent Estimates

Weekly estimates track parental intent for vaccination and cumulative vaccination coverage among children aged 6 months to 17 years in the United States. Data originates from the National Immunization Survey-Child COVID Module and its successor, the National Immunization Survey-Flu, collected via national random-digit-dial telephone surveys. The dataset includes weekly snapshots through December 31, 2023, with updates continuing via the NIS-Flu survey.

Use Cases

• Analyze trends in `Estimate` for `Indicator_label` like 'Up to date with COVID-19 vaccines' across different `Demographic_Name` groups.
• Model weekly `vaccine` coverage rates using `Week_ending` and `Geographic_Name` to forecast regional uptake.
• Assess data reliability by examining `CI_Half_width_95pct` and `Unweighted_Sample_Size` for specific `Demographic_Level` categories.
• Compare `Indicator_category_label` values such as 'Parental Intent for Vaccination' against actual coverage estimates over a `Month_Week` series.

Strengths

• Includes weekly granularity for tracking rapid changes in vaccination intent and coverage.
• Provides confidence intervals via `CI_Half_width_95pct` and sample sizes via `Unweighted_Sample_Size` for statistical reliability assessment.
• Covers multiple demographic and geographic levels (`Demographic_Level`, `Geographic_Level`) for subgroup analysis.

Limitations

• All estimates rely on parental self-report, which may introduce recall or social desirability bias.
• Survey methodology shifted from NIS-CCM to NIS-Flu after 2023, potentially affecting continuity.
• Data posted has a noted lag of a few days behind other CDC data channels due to review processes.
