Vaccines in Long-Term Care Settings: A Narrative Review.

Background: Older people living in long-term care facilities represent a particularly vulnerable segment of the population, who disproportionately bear the burden of infectious diseases, as recently highlighted by the COVID-19 pandemic.

Summary: Older long-term care residents typically cumulate several risk factors for infection and experience serious life-threatening outcomes once infected. These common infections are often compounded by the collective living environment, where it is more difficult to contain the spread of infection. Moreover, the staff may represent an additional reservoir of potential infection and mode of transmission. In this paper, we review the burden of infectious respiratory diseases in residents in long-term care and discuss the potential gains from higher vaccine coverage in this older and most vulnerable population but also from higher vaccine coverage among the facility staff. We highlight the compelling need to integrate specific vaccine recommendations for residents of long-term care into national vaccination schedules, as well as the need to include vaccination campaigns in routine protocols for infection control. Surveillance, reporting, hygiene, and individual protective measures remain key aspects in basic infection control, both in ordinary times and during epidemics.

Key message: Vaccination of residents in long-term care facilities against respiratory diseases including influenza, pneumococcal disease, pertussis, and COVID is a simple, inexpensive, and effective means to reduce the burden of infection in this segment of the population.
