COVID-19 Vaccine Uptake Among Nursing Home Staff via Statewide Policy: The Mississippi Vaccinate or Test Out Policy.

To examine whether COVID-19 vaccine mandates that allow a test-out exemption for nursing home staff are associated with increased staff vaccination rates in nursing homes. Using the National Healthcare Safety Network data, we conducted analyses to test trends over time in statewide staff vaccination rates between June 1, 2021, and August 29, 2021, in Mississippi, 4 adjacent states, and the United States overall. COVID-19 staff vaccination rates increased slowly following Mississippi enacting a vaccinate-or-test-out policy, achieving small, but statistically greater gains than most comparator states. Yet, staff vaccination rates in Mississippi remained well below the national average and similar numerically to surrounding states without mandates. Mississippi's COVID-19 vaccinate-or-test policy was ineffective in meaningfully increasing staff vaccination rates. For COVID-19 nursing home mandates to be effective while still balancing the staff turnover risks, facilities might consider a more stringent or hybrid approach (e.g., test-out option not offered to new staff). Statewide COVID-19 vaccine mandates, when given a test-out option, do not appear to be an effective strategy to meaningfully increase nursing home staff COVID-19 vaccination.
