Vaccines against the human papillomaviruses (HPVs) most frequently associated with cancer of the cervix are now available. These prophylactic vaccines, based on virus-like particles (VLPs), are extremely effective, providing protection from infection in almost 100% of cases. However, the vaccines present some limitations: they are effective primarily against the HPV type present in the vaccine, are expensive to produce, and need a cold chain. Vaccines based on the minor capsid protein L2 have been very successful in animal models and have been shown to provide a good level of protection against different papillomavirus types. The potential of L2-based vaccines to protect against many types of HPVs is discussed.
目前已有针对与宫颈癌最相关的人类乳头瘤病毒(HPV)的疫苗。这些基于病毒样颗粒(VLPs)的预防性疫苗非常有效,几乎能 100%预防感染。然而,这些疫苗存在一些局限性:它们主要针对疫苗中存在的 HPV 类型有效,生产成本高,并且需要冷链。基于次要衣壳蛋白 L2 的疫苗在动物模型中非常成功,并已证明能提供针对不同乳头瘤病毒类型的良好保护水平。讨论了基于 L2 的疫苗预防多种 HPV 的潜力。
