The widely used hepatitis B virus (HBV) vaccine is based on three doses of hepatitis B surface antigen (HBsAg) protein. We previously showed that vectored measles viruses (MV) expressing HBsAg retain measles vaccine function in monkeys but do not induce a protective anti-HBs response in all animals. We show here that a single dose of HBsAg protein following a three-dose vaccination regimen with an optimized HBsAg-expressing MV elicits protective anti-HBs responses in all four vaccinated Rhesus monkeys. Vaccination strategies coupling the effective, long-term immunity elicited by the high-coverage MV vaccine to prophylactic HBV immunity are discussed.
广泛使用的乙型肝炎病毒(HBV)疫苗是基于三剂乙型肝炎表面抗原(HBsAg)蛋白。我们之前表明,表达HBsAg的载体麻疹病毒(MV)在猴子中保留了麻疹疫苗功能,但并非在所有动物中都能诱导出保护性抗-HBs反应。我们在此表明,在使用优化的表达HBsAg的MV进行三剂疫苗接种方案后,单剂量的HBsAg蛋白能在所有四只接种疫苗的恒河猴中引发保护性抗-HBs反应。文中讨论了将高覆盖率MV疫苗引发的有效、长期免疫与预防性HBV免疫相结合的疫苗接种策略。
