题目分析：
本题中出现了平行制造者either…or…，该连词连接的两者需要在逻辑上和语形上保持一致。
选项分析：
A选项：such…as…和like都能近似表达举例，但是唯独such…like…不行；另外，vaccination应该改为动名词vaccinating。这点考查了“名词和ing的区别”。用之于本题，“努力（efforts）”本身就表示一种过程（已经有结果了的话，就不用努力了），即，努力关注的应该是给人类打疫苗和消灭蚊子的过程，从中我们无法得知“接种疫苗”和“消灭蚊子”这两件事是否具有时间的终止点。
B选项：such…like…错误同(A)；extermination应改为动名词，该错误同选项(A)。
C选项：either…or…连接的两者需要在语法上保持严格平行。
D选项：either…or…平行错误同(C)；extermination应改为动名词，该错误同选项(A)。
E选项：Correct. 本选项在语法和逻辑上均是正确的。
ing和ing平行，名词和名词平行
