Emergence of SARS-CoV-2 immune escape variants in an immunocompromised patient

A German case study recently published in the journal Nature Communications has characterized a long-term severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection dynamics in an immunosuppressed kidney transplant recipient and provided evidence for the evolution of SARS-CoV-2 into potentially harmful immune escape mutants during persistent infections.

Finnish study highlights the need for mRNA COVID vaccine booster shots

A register-based cohort study of the effectiveness of COVID-19 vaccines was performed to help decision-making on providing booster doses to social and healthcare workers (HCWs) like nurses, physicians, dentists, and other professionals in Finland. In addition, it estimated the vaccine effectiveness after the second dose. This study is published on the medRxiv* preprint server.
