JEFFERSON CITY, MO – Nursing homes have experienced a significant amount of SARS-CoV-2 transmission resulting in hospital admissions and severe outcomes throughout the COVID-19 pandemic. Findings from a large study including hundreds of nursing homes recently published by JAMA Network Open suggest that administration of a SARS-CoV-2 mRNA vaccine booster among nursing home residents may have played an important role in preventing COVID-19-associated morbidity and mortality. 

Authors of the study stated, “During a period in which both the Delta and Omicron variants were circulating, SARS-CoV-2 booster vaccination was associated with significant reductions in SARS-CoV-2 infections, hospitalizations, and the combined end point of hospitalization or death among residents of two U.S. nursing home systems.”

Throughout Missouri skilled nursing facilities, an average of just 45% of current residents per facility are up to date on COVID-19 vaccines (based on available facility reporting). Missouri has one of the lowest rates of vaccination among long-term care facility staff in the nation. And among all eligible Missourians age 65 and older, only 35% have received an updated booster dose.

COVID-19 vaccines continue to be widely available. Visit to find a Missouri COVID-19 vaccinator near you.
