COVID-19 Vaccination Attitudes and Intentions Among U.S. Soldiers: Results from the U.S. Army Behavioral Health Advisory Team (BHAT).

introductionThe objective of this study is to characterize the associations between demographic, attitudinal, and leadership factors with COVID-19 vaccination rates, vaccination intentions among those not vaccinated, and attitudes about vaccination safety, effectiveness, and importance.

methodsA serial cross-sectional anonymous online survey was administered to soldiers at two large U.S. Army Divisions located in the Southwestern region of the U.S. at two different time points (April-May 2021 [Time 1; T1] N = 24,629; July-August 2021 [Time 2; T2] N = 21,116). Binary logistic regressions were used to assess demographic and attitudinal predictors of vaccination receipt and vaccination intent. Multinomial logistic regressions were used to assess demographic and leadership predictors of endorsement of three vaccination attitudes concerning effectiveness, safety, and importance.

resultsApproximately 43% of soldiers reported that they received a COVID-19 vaccine at T1, increasing to 67% at T2. Soldiers who agreed with three separate statements on vaccination effectiveness, safety, or importance were more likely to indicate that they intended to get the vaccination at both time points. Soldiers who reported that their immediate supervisor encouraged soldiers to get a COVID-19 vaccine were more likely to indicate that the vaccination was effective, safe, or important at both time points. DISCUSSION: Negative attitudes about COVID-19 vaccines were prevalent and correlated with less intention to get a vaccination. However, prioritizing leadership engagement around the importance of vaccinations may be a simple but widely effective intervention point to increase future vaccine uptake following the development of novel vaccines to future COVID-19 variants.
