Vaccination with DNA and recombinant vaccinia viruses (rec.VV) has been studied with the coxsackievirus B3 (CVB3) model system. Plasmids encoding all structural proteins of CVB3, when injected intramuscularly, induced only low levels of virus-specific antibodies. However, DNA vaccination with the major structural protein VP1 protected 72.2% of mice from lethal challenge, whereas VP1 expressed by rec.VV was much less efficient.
已利用柯萨奇病毒B3(CVB3)模型系统对DNA疫苗和重组痘苗病毒(rec.VV)疫苗接种进行了研究。编码CVB3所有结构蛋白的质粒经肌肉注射后,仅诱导产生低水平的病毒特异性抗体。然而,用主要结构蛋白VP1进行DNA疫苗接种可使72.2%的小鼠免受致死性攻击,而rec.VV表达的VP1效率则低得多。
