All vaccination strategies, regardless of the order or combination, provided 100% protection to immunized mice, irrespective of the status of IL-17A depletion, while 100% lethality was observed in unvaccinated control mice (given phosphate-buffered saline [PBS] as a vehicle) 3 days post-infection (d.p.i.)(Figure 1B,C). This evidence concerns the gene IL17A and infection.
