  • Data from a voluntary surveillance program at a single medical center in Italy revealed that 11 healthcare workers who had been fully vaccinated with the Pfizer-BioNTech vaccine had SARS-CoV-2 detected in nasopharyngeal swabs and 5 of these persons had mild symptoms. The average cycle threshold (Ct) in detected infections was 19 (range 6-26). However, no cases of nosocomial transmission were documented from these healthcare workers to patients. [EDITORIAL NOTE: This article did not report the number of vaccinated health care workers from among which the 11 SARS-CoV-2-positive individuals emerged, which makes it impossible to determine the incidence of infection among fully vaccinated individuals.]
