Vaccination is mankind's greatest public health success story. By now vaccines to many of the viruses that once caused fatal childhood diseases are routinely used throughout the world. Traditional methods of vaccine development through inactivation or attenuation of viruses have failed for some of the most deadly human pathogens, necessitating new approaches. Genetic modification of viruses not only allows for their attenuation but also for incorporation of sequences from other viruses, turning one pathogen into a vaccine carrier for another. Recombinant viruses have pros and cons as vaccine carriers, as discussed below using vectors based on adenovirus, herpesvirus, flavivirus, and rhabdovirus as examples.
疫苗接种是人类最伟大的公共卫生成就之一。如今,针对许多曾经导致致命儿童疾病的病毒的疫苗已在全球范围内常规使用。对于一些最致命的人类病原体,通过使病毒失活或减毒来开发疫苗的传统方法已经失败,因此需要新的方法。对病毒进行遗传修饰不仅可以使其减毒,还可以将来自其他病毒的序列整合进去,从而使一种病原体成为另一种病原体的疫苗载体。下面将使用基于腺病毒、疱疹病毒、黄病毒和弹状病毒的载体为例,讨论重组病毒作为疫苗载体的优缺点。
