Weekly Pediatric Influenza Vaccination Coverage in the United States

Weekly cumulative influenza vaccination coverage estimates for children aged 6 months through 17 years, based on the National Immunization Survey-Flu. The data is collected annually via a national random-digit-dialed cellular telephone survey conducted during the flu season from October to June. Coverage estimates are derived from parental reports.

Use Cases

• Analyze weekly trends in vaccination coverage for children aged 6 months through 17 years across flu seasons.
• Model the relationship between survey timing during the October-June flu season and reported cumulative coverage.
• Compare vaccination coverage estimates derived from parental reports across different demographic segments implied by the survey methodology.

Strengths

• Data is sourced from the National Immunization Survey-Flu, a national survey conducted by the CDC.
• Provides weekly granularity for tracking vaccination coverage throughout the flu season.
• Covers a specific and policy-relevant population: children from 6 months to 17 years old.

Limitations

• Coverage estimates are based on parental report, which may introduce recall or social desirability bias.
• The dataset's temporal coverage is not explicitly stated, limiting analysis of long-term trends.
• Lack of column-level detail prevents assessment of data granularity and available demographic variables.
