ABSTRACT
PURPOSE OF REVIEW To explore the origins of new severe acute respiratory coronavirus 2 (SARS-CoV-2) variants in immunocompromised individuals and whether the emergence of novel mutations in these individuals is responsible for the development of variants of concern (VOC). RECENT FINDINGS:
Next generation sequencing of samples from chronically infected immunocompromised patients has enabled identification of VOC- defining mutations in individuals prior to the emergence of these variants worldwide. Whether these individuals are the source of variant generation is uncertain. Vaccine effectiveness in immunocompromised individuals and with respect to VOCs is also discussed.SUMMARY:
Current evidence on chronic SARS-CoV-2 infection in immunocompromised populations is reviewed including the relevance of this to the generation of novel variants. Continued viral replication in the absence of an effective immune response at an individual level or high levels of viral infection at the population level are likely to have contributed to the appearance of the main VOC.
