Weekly RSV Vaccination Coverage Differences Among High-Risk Older Adults

Weekly estimates track differences in cumulative RSV vaccination coverage between demographic groups of adults aged 60-74 with high-risk conditions and those 75 and older. Data originates from the CDC's National Immunization Survey–Adult COVID Module (NIS–ACM), with the latest update in May 2025. It captures vaccination trends following the 2023 and 2024 ACIP recommendations for RSV vaccine use in these populations.

Use Cases

• Analyze temporal trends in vaccination disparity using the 'Week Ending' and 'Estimate Difference' columns.
• Compare coverage gaps between demographic subgroups defined in 'Comparison Group 1' and 'Comparison Group 2'.
• Identify statistically significant coverage differences flagged by the 'Significant_at_95_pct' column.
• Assess coverage estimates and confidence intervals via 'Comparison Group 1 Estimate', 'Difference_Estimate_Lower_95_CI', and 'Difference_Estimate_Upper_95_CI' fields.

Strengths

• Weekly granularity enables tracking of short-term trends following policy recommendations.
• Includes statistical significance indicators ('Significant_at_95_pct') and confidence intervals for difference estimates.

Limitations

• Sample size and row count are unknown, limiting assessment of statistical power.
• Geographic coverage is unspecified, potentially masking regional biases.
• Data relies on self-reported survey responses from the NIS-ACM, which may contain recall bias.
