Deltaasp24 mutants showed superior protection compared to current vaccine strains and other deletion mutants (deltamanba and deltavirb2) against homologous and heterologous challenge infections. No direct association between protection and cytokine response was apparent. PMID:17664263 PMID:16790778 12108 VaxAgent vaccine Jie Zheng live attenuated vaccine role
