Observational study tracks influenza and COVID-19 vaccination coverage in US health care personnel

This observational study monitored influenza and COVID-19 vaccination coverage among health care personnel in the United States. The surveillance period ran from October 1, 2023, to March 31, 2024. The study did not report a specific sample size, comparator group, or the exact vaccination coverage rates for either influenza or COVID-19 vaccines. No quantitative results, effect sizes, or statistical measures were provided for the primary outcomes of vaccination coverage.

No safety or tolerability data regarding the vaccinations were reported in this surveillance analysis. The study did not detail any adverse events, serious adverse events, or discontinuations related to vaccination.

Key limitations include the lack of reported numerical data, making it impossible to quantify coverage levels or trends. The absence of a comparator group prevents any assessment of relative performance or factors influencing vaccination uptake. The practice relevance is limited, as the findings do not offer actionable metrics for improving vaccination programs. This report serves primarily as a notice of ongoing surveillance rather than an analytical study.
