Summary

The proportion of deaths directly attributable to COVID-19 among patients who died within 30 days of a positive test declined significantly from over 70% to less than 50% between August 2021 and March 2023. This downward trend was similar for both vaccinated and unvaccinated veterans, suggesting that increased population immunity and improved therapeutics reduced the relative impact of the virus on mortality across both groups.

Key result
