Th17-associated immune responses can be targeted for strategies to mitigate distal infections originating from persistent S. aureus carriage in humans [27].Considering that one of the reasons for the failure of the V710 vaccine against S. aureus and increased mortality of vaccine recipients was low serum IL-2 and IL-17A concentrations, it can be concluded that IL17a is critical in eradicating S. aureus in the host [28]. Here, IL17A is linked to infection.
