Few SARS-CoV-2 vaccine breakthrough infections reported at SNFs

(HealthDay)—Few cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections have been reported at skilled nursing facilities (SNFs) among those with at least 14 days since receipt of the second dose of a two-dose COVID-19 vaccine series, according to research published in the April 21 early-release issue of the U.S. Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report.

Noting that in February 2021, the Chicago Department of Public Health identified a SARS-CoV-2 infection in an SNF resident >14 days after receipt of the second dose of a two-dose COVID-19 vaccination series through routine screening, Richard A. Teran, Ph.D., from the CDC in Atlanta, and colleagues examined SARS-CoV-2 cases, vaccination status, and possible vaccine breakthrough infections in facility reports.

The researchers found that among 627 persons with SARS-CoV-2 infection across 75 SNFs since vaccination clinics began, there were 22 SARS-CoV-2 infections in residents and staff members (12 and 10, respectively) at 15 facilities ≥14 days after receipt of a second dose. Fourteen (64 percent) of those with breakthrough infections were asymptomatic, while two residents were hospitalized due to COVID-19 and one died. There were no facility-associated secondary transmissions observed.
