Abstract

This retrospective cross-sectional study reviewed the association between COVID-19 vaccination and the 28-day all-cause mortality amongst SARS-CoV-2-infected older people living in residential aged care facilities. A lower mortality rate was observed in fully vaccinated residents compared with not fully vaccinated residents. Further research is required to investigate the optimal timing of vaccination boosters and vaccine efficacy as variants evolve.

Keywords: COVID-19 vaccine; SARS-CoV-2 infection; morbidity; mortality; residential facilities.
