Participants included the residents of 15 042 US  nursing homes that reported COVID-19 data to the Centers  for Disease Control and Prevention and passed Centers for  Medicare &amp; Medicaid Services data quality checks in the  National Healthcare Safety Network.&lt;/p&gt; &lt;p&gt;Exposures:  Weekly staff vaccination rates.&lt;/p&gt; &lt;p&gt;Main Outcomes and  Measures: Main outcomes are weekly COVID-19 cases and  deaths among residents and weekly COVID-19 cases among  staff. The treatment variable is the primary 2-dose staff  vaccination rate in each facility each week.&lt;/p&gt;  &lt;p&gt;Results: In the primary analysis of 15 042 nursing homes  before the Omicron variant wave (May 30 to December 5,  2021) using fixed effects of facility and week, increasing  weekly staff vaccination rates by 10 percentage points was  associated with 0.13 (95% CI, −0.20 to −0.10) fewer weekly  COVID-19 cases per 1000 residents, 0.02 (95% CI, −0.03 to  −0.01) fewer weekly COVID-19 deaths per 1000 residents, and  0.03 (95% CI, −0.04 to −0.02) fewer weekly COVID-19 staff  cases. In the secondary analysis of the Omicron wave  (December 5, 2021, to January 30, 2022), increasing staff  vaccination rates were not associated with lower rates of  adverse COVID-19 outcomes in nursing homes.&lt;/p&gt;  &lt;p&gt;Conclusions and Relevance: The findings of this cohort  study suggest that before the Omicron variant wave,  increasing staff vaccination rates was associated with  lower incidence of COVID-19 cases and deaths among  residents and staff in US nursing homes. However, as newer,  more infectious and transmissible variants of the virus  emerged, the original 2-dose regimen of the COVID-19  vaccine as recommended in December 2020 was no longer  associated with lower rates of adverse COVID-19 outcomes in  nursing homes. Policy makers may want to consider  longer-term policy options to increase the uptake of  booster doses among staff in nursing homes.&lt;/p&gt;},
