COVID-19 Infection and Immunity in Residents of Long-term Care Facilities
The objectives of the study are:
* To understand which features of long-term care facilities are associated with COVID-19 outbreaks
* To determine if long-term care homes that have had outbreaks or had staff infected are less likely to have outbreaks in the future
* To discover whether a resident's immune response or previous exposure can protect them or make them vulnerable to infection
* To determine how well vaccinations work in residents of long-term care homes
