Risk factors for Omicron reinfections among previously infected frontline workers in the United States

Researchers examined a prospective cohort of frontline workers in the United States (US) previously infected with SARS-CoV-2. They attempted to identify risk factors that made this highly vulnerable population prone to reinfection by SARS-CoV-2 new variant of concern (VOC), Omicron, known for its high immune evading potential.

Study assesses the sensitivity, specificity of rapid antigen tests and PCR tests for Omicron variant of COVID-19

Testing plays a crucial role in humanity's strategy to mitigate the effects of widespread COVID-19 infection. However, given multiple options for testing and the emergence of the highly contagious Omicron variant, how do we choose which test to use?

Does a second monovalent SARS-CoV-2 mRNA booster increase neutralizing activity to Omicron variants in nursing home residents and healthcare workers?

Researchers investigated whether the second booster dose of monovalent COVID-19 mRNA vaccines increases antibody titers and neutralization potential against the SARS-CoV-2 Omicron VOC among NH residents and HCWs.

30 Jan 2023

Study suggests robust lung mucosal immunity against SARS-CoV-2 can be better achieved through hybrid immunity, as opposed to peripheral vaccination alone

Researchers characterized immunological responses by pulmonary mucosal tissues post-COVID-19 vaccination and/or SARS-CoV-2 infection, to assess the impact of hybrid immune protection on the durability of mucosal immunological responses.
