The development of an effective, affordable prophylactic vaccine against hepatitis C virus (HCV) remains a medical priority. The recently described chimeric HBV-HCV subviral envelope particles could potentially be used for this purpose, as they could be produced by industrial procedures adapted from those established for the hepatitis B virus (HBV) vaccine. We show here, in an animal model, that pre-existing immunity acquired through HBV vaccination does not influence the immunogenicity of the HCV E2 protein presented by these chimeric particles. Thus, these chimeric HBV-HCV subviral envelope particles could potentially be used as a booster in individuals previously vaccinated against HBV, to induce protective immunity to HCV.
开发一种有效且价格合理的丙型肝炎病毒(HCV)预防性疫苗仍是医学上的一项优先任务。最近描述的嵌合型乙肝病毒-丙肝病毒亚病毒包膜颗粒有可能用于此目的,因为它们可以通过借鉴乙肝病毒(HBV)疫苗的现有工业生产流程来制备。我们在此动物模型中表明,通过接种乙肝疫苗获得的既往免疫力不会影响这些嵌合颗粒所呈现的丙肝病毒E2蛋白的免疫原性。因此,这些嵌合型乙肝病毒-丙肝病毒亚病毒包膜颗粒有可能用作曾接种过乙肝疫苗个体的加强针,以诱导对丙肝病毒的保护性免疫。
