Effectiveness of mRNA COVID-19 Booster Vaccines against Omicron and Delta Variants among US Veterans

2022-01-18

Abstract excerpt

<h4>Background</h4> We estimated vaccine effectiveness (VE) of mRNA vaccines among US Veterans during periods of Delta and Omicron variant dominance. Patients included in this study were largely 65 years or older (62,834, 55%), male (101,259, 88%), and non-Hispanic white (66,986, 58%). <h4>Methods</h4> We used SARS-CoV-2 laboratory test results to conduct a matched test-negative case-control study to estimate VE o...
