Method & caveats. CDC FluVaxView season estimate for adults aged 65 years or older. The NHIS past-12-months self-report by calendar year and the FluVaxView season estimate are a paired comparison of two different instruments and must not be spliced into one series. Season or school year is mapped to the calendar year it ends (e.g. '2023-24' -> 2024). Uses the maximum cumulative coverage per season, verified against the latest observation in July-to-June month order. The 2009-10 H1N1 season, which FluVaxView reports with three different end-of-season figures per age group, is excluded; the series begins with 2010-11. The 2023-24 season, which the dataset labels differently, is included under the same age group.
