Elderly people might not benefit from some of the tuberculosis vaccines currently in development, recent research suggests. Some vaccines under study are designed to activate a specific molecule that is an early participant in the immune response against TB in young people. But a recent study suggests that in older people, this molecule remains relatively inactive, even in the face of TB infection.
