Because, nucleic acidvaccine could simultaneously induce cellular immunity and humoral immunity, which couldproduce chiasma protection to different serological types of virus strains, nucleic acid vaccine washopefully to become the important researching direction.
由于核酸疫苗可同时诱导细胞免疫和体液免疫，可以对不同血清型的毒株产生交叉保护性，因此核酸疫苗有望成为重要研究方向。
