Hepatitis A represents one of the major public health problems worldwide including India. Vaccination is the most effective way to prevent hepatitis A infection. Two types of hepatitis A vaccines-live attenuated (H2 strain) and inactivated (killed) are available for use in clinical practice in India with former having advantage of a single-dose compared to two-dose killed vaccine. One of the important characteristic of an ideal vaccine includes its ability to provide life-long protection. In this article we reviewed the available long-term (≥10 years follow-up) published data on live attenuated hepatitis A (H2 strain) vaccine. The data from country of origin of the vaccine (China) and India establish the long-term immunogenicity, protection, and tolerability. Based on the results of several clinical trials showing long-term protection, single dose of live attenuated hepatitis vaccine can be widely used to protect high-risk population against hepatitis A virus infection and related complications.
甲型肝炎是包括印度在内的全球主要公共卫生问题之一。接种疫苗是预防甲型肝炎感染的最有效方法。在印度临床实践中可使用两种甲型肝炎疫苗——减毒活疫苗(H2株)和灭活(死)疫苗,与两剂次的灭活疫苗相比,前者具有单剂次接种的优势。理想疫苗的一个重要特性包括其提供终身保护的能力。在本文中,我们回顾了已发表的关于甲型肝炎减毒活疫苗(H2株)的长期(≥10年随访)数据。来自疫苗原产国(中国)和印度的数据证实了其长期免疫原性、保护作用和耐受性。基于多项显示长期保护作用的临床试验结果,单剂次甲型肝炎减毒活疫苗可广泛用于保护高危人群免受甲型肝炎病毒感染及相关并发症。
