S. aureus
α-toxin (Hla) is an essential virulence factor in disease, impairing the T cell response to infection. The anti-Hla antibody response is a correlate of human protective immunity. Here we observe that this response is limited early in human life and design a vaccine strategy to elicit immune protection against Hla in a neonatal mice. By targeted disruption of the interaction of Hla with its receptor ADAM10, we identify a vaccine antigen (Hla

) that elicits an ~100-fold increase in the neutralizing anti-Hla response. Immunization with Hla

enhances the T follicular helper (T

) cell response to
S. aureus
infection, correlating with the magnitude of the neutralizing anti-toxin response and disease protection. Furthermore, maternal Hla

immunization confers protection to offspring. Together, these findings illuminate a path for
S. aureus
vaccine development at the maternal-infant interface.
Staphylococcus aureus
infection results in robust induction of immunity but the development of efficacious vaccines remains challenging. Here the authors present a vaccine that amplifies T cell immunity early in life by targeting the

α-toxin-ADAM10 interaction in a murine model. |
