• Twenty-two possible breakthrough SARS-CoV-2 infections (infection ≥14 days after the second vaccine dose) were identified among skilled nursing facility staff (n = 10) and residents (n = 12) across 15 facilities in the Chicago, IL area. Among these cases, 14 (64%) were asymptomatic, two residents were hospitalized, and one resident died due to multiple concurrent infections (Group B streptococcal bacteremia and Pseudomonas urinary tract infection). No facility-associated secondary transmission occurred. PCR cycle threshold values from seven patients with breakthrough infections were above 28, suggesting low viral loads.
