Persistence of Anti-SARS-CoV-2 Antibodies in Long Term Care Residents Over Seven Months After Two COVID-19 Outbreaks

The COVID-19 pandemic remains a public health challenge worldwide, and there is a paucity of evidence investigating the long-term durability of SARS-CoV-2 antibodies in high-risk populations, such as the elderly. We evaluated the antibody responses to SARS-CoV-2 and endemic human coronaviruses in long term care residents following two COVID-19 outbreaks in the same facility, seven months apart. Our findings support and expand on current knowledge, and can help guide public health measures and vaccine implementation guidelines.
