Association between COVID-19 vaccination and 28-day all-cause mortality in SARS-CoV-2-infected older people living in residential aged care facilities.

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.

Residential aged care facility COVID-19 outbreaks and magnitude of spread among residents: observations from a Victorian residential in-reach service.

There is a paucity of Australian literature exploring the spread of COVID-19 among residents living in residential aged care facilities (RACF). In this case series of COVID-19 outbreaks in six RACF, we collected data on the cumulative proportion of residents who tested positive for COVID-19 within 21 days of the index case being identified. We describe the observations of a Residential In-Reach service within these six RACF and found that rapid cohorting strategies, personal protective equipment availability and adequacy of use, embedded infection control staff, and adequate outbreak preparedness plans may have influenced the differences observed between RACF in the containment and minimisation of the spread of COVID-19 amongst residents.
