作者从成本-效果上分析了比化疗更经济有效的血吸虫病疫苗的某些持点。 化疗或疫苗的效果通过目标人群、疫苗效率(e)、覆盖面(v)及其接受药物或疫苗的依从性(p)确定。假设这3个参数为非年龄依赖的。无论化疗还是疫苗接种,3个参数基准值分别为0.9,0.9和0.8,单位成本均为1美元。假设疫苗保护性作用不因重复感染而加强。模型A(疫苗具长期保护力)是疫苗最 The authors analyzed some of the cost-effectiveness of schistosomiasis vaccines that are more cost-effective than chemotherapy. The efficacy of the chemotherapy or vaccine is determined by the target population, vaccine efficiency (e), coverage (v), and compliance with the drug or vaccine (p). The three parameters are assumed to be non-age dependent. Regardless of chemotherapy or vaccination, the three parameters were 0.9, 0.9 and 0.8 respectively, and the unit cost was US $ 1. It is assumed that the vaccine’s protective effect is not enhanced by repeated infections. Model A (vaccine with long-term protection) is the most vaccine
