Addition of adjuvant to DTaP modulates vaccine-induced immunological responses but is insufficient to improve protection in CD-1 mice

This study evaluates if adding adjuvants to DTaP improves protection in CD-1 mice against Bordetella pertussis, finding that while adjuvants enhance immune markers, they do not improve protection.
