Description:

What is already known about this topic? mRNA COVID-19 vaccines are effective in preventing severe COVID-19 outcomes, including hospitalization.

What is added by this report? During February 1–August 6, 2021, vaccine effectiveness among U.S. veterans hospitalized at five Veterans Affairs Medical Centers was 87%. mRNA COVID-19 vaccines remain highly effective, including during periods of widespread circulation of the SARS-CoV-2 B.1.617.2 (Delta) Variants. Vaccine effectiveness in preventing COVID-19–related hospitalization was 80% among adults aged ≥65 years compared with 95% among adults aged 18–64 years.

What are the implications for public health practice? To protect against COVID-19–related hospitalization, all eligible persons should receive COVID-19 vaccination. Additional studies are needed to understand differences in COVID-19 vaccine effectiveness across age groups.
