Limits of this measure
Final mortality data. CDC publishes this series per 100,000 live births. It is not the adult death rate. The 2023 to 2024 difference was not statistically significant in the source report.
Daily source checks do not create new daily observations. Figures may be revised, and timing does not establish administration causation. This record is informational and should not guide financial or medical decisions.
