Data from the National Immunization Surveys – Fall Respiratory Virus Module provides monthly estimates of infant protection against Respiratory Syncytial Virus (RSV). Estimates are based on parent-reported data from adult females aged 18–49 years with infants under 8 months old born since April 1, 2025. The dataset tracks protection via maternal RSV vaccination, infant receipt of RSV monoclonal antibodies, and intent for antibody receipt.
Use Cases
- Analyze geographic variation in infant RSV protection using the 'Geographic Label' and 'Estimate' columns.
- Assess statistical reliability of coverage estimates by examining 'Sample Size' and '95% Confidence Interval'.
- Track monthly trends in maternal vaccination and monoclonal antibody intent via the 'Timeframe' and 'Indicator Variable' fields.
- Identify data suppression issues for small sample sizes using the 'Suppressed Flag' column.
Strengths
- Data sourced from the ongoing National Immunization Surveys, a recognized public health surveillance system.
- Includes statistical reliability metrics via '95% Confidence Interval' and 'Sample Size' columns.
- Provides monthly granularity for tracking trends over time.
Limitations
- All estimates rely on parent-reported data, which may be subject to recall or social desirability bias.
- Sample size and row count are unknown, limiting assessment of statistical power.
- Geographic coverage specifics beyond the column name are not detailed.
