The benefits of having more nursing home staff take COVID-19 vaccines faded as the Omicron variant took hold, a new study of some 15,000 facilities across the United States suggests.
The authors of the study, a team of researchers from the University of Chicago, sought to find out whether higher levels of staff vaccination rates were actually associated with lower adverse outcomes of COVID-19 in nursing homes. As of Dec. 19, 2022, two weeks before their paper was published online in JAMA Network Open, nursing home staff and residents accounted for nearly 2.9 million COVID-19 infections and 165,000 deaths.
