Article Synopsis
- The study investigated the characteristics of healthcare personnel (HCP) who tested positive for SARS-CoV-2 from April 2020 to December 2021 to inform protective measures for this workforce.
- Over 7,500 case-HCP were analyzed, revealing that a significant proportion of certified nursing assistants, medical assistants, and home healthcare workers identified as non-Hispanic Black or Hispanic, with many residing in areas of high social vulnerability.
- Findings suggest that tailored infection prevention strategies should be developed according to HCP roles and social vulnerability to effectively reduce the risk of SARS-CoV-2 infection.
Article Synopsis
- The study examined the effectiveness of mRNA vaccines (Pfizer-BioNTech and Moderna) against COVID-19 among U.S. health care personnel who were prioritized for early vaccination.
- It utilized a test-negative case-control design, comparing vaccinated individuals with positive SARS-CoV-2 tests (cases) to those with negative tests (controls) while adjusting for various demographics and health factors.
- Results showed that partial vaccination had effectiveness rates of 77.6% for Pfizer and 88.9% for Moderna, while complete vaccination led to 88.8% and 96.3% effectiveness, respectively, with some variations noted in specific demographic subgroups and over time.
Healthcare personnel with severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection were interviewed to describe activities and practices in and outside the workplace. Among 2,625 healthcare personnel, workplace-related factors that may increase infection risk were more common among nursing-home personnel than hospital personnel, whereas selected factors outside the workplace were more common among hospital personnel.

Article Synopsis
- Health care personnel (HCP) were prioritized for COVID-19 vaccination to protect them from SARS-CoV-2 exposure and ensure ongoing health services during the pandemic.
- Early distributions of Pfizer-BioNTech and Moderna vaccines allowed for real-world effectiveness assessments among HCP at 33 U.S. sites.
- Interim analyses showed a vaccine effectiveness of 82% after one dose and 94% after two doses, confirming their strong protection against symptomatic illness comparable to clinical trial results.
