New data from McMaster researchers has found waning levels of antibodies in some long-term care residents months after their second COVID-19 vaccines, directly supporting government decisions to provide third doses.
More than 90 per cent of residents in long-term care facilities created an initial immune response after two doses of COVID-19 vaccine, and researchers recommend third-dose boosters be provided immediately.
Homes with large numbers of residents and staff suffered a threefold higher risk of being hit by COVID-19 last year, likely because of more staff coming in and out when providing care.
