The bidirectional communication axis between the gut and lungs, called the “gut–lung axis” influences the immune status of both organs.

Lung and gut microbiota influence each other and may have an impact on respiratory diseases.4

1 1 factor known to control vaccine efficacy can be gut microbiota.(5)

DYSBIOSIS

Lung and gut dysbiosis are observed during viral respiratory infections.6 Common definition of dysbiosis describes it as a compositional and functional alteration in the microbiota that is driven by a set of environmental and host-related factors that perturb the microbial ecosystem.7
