Description
Gokhan Tut and co-authors, in a 2026 study, tracked COVID-19 immunity and reinfection among older people living in long term care homes. These residents suffered very high death rates early in the pandemic. Their risk has since fallen sharply with vaccination, but how long protection lasts in this frail group is a live question.
The team measured blood and cell immunity after a fifth vaccine dose, a mixed strain mRNA shot. Immunity tied to the virus spike rose to a plateau, and stayed broadly steady for about 100 days in almost all residents. Yet over six months of follow up, 15 percent had a first infection and 30 percent were infected again. The gap between strong lab immunity and real reinfection is the study's central, sobering point for care home policy.
