“This is based on(基于，根据) what I feel.” That was the president last September, explaining why he wanted the measles, mumps and rubella (MMR) vaccine broken into three separate shots.(那是总统去年九月的表态，解释他希望将麻腮风疫苗拆分为三种单独接种的针剂。) On Monday, he signed an executive order(行政命令) instructing(指示，命令) exactly that.
“这是基于我的感受。”这是总统去年九月说的话，当时他解释为何希望将麻疹、腮腺炎和风疹（MMR）疫苗拆分为三种单独接种的针剂。周一，他签署了一项行政令，指示正是如此执行。
Four decades in intensive care(重症监护) have taught me what a feeling costs once it becomes national policy. Children will be hospitalized who did not need to be. Some of them will die. No one can name those the vaccine has saved, because prevented harm is invisible by definition, and that invisibility is what makes preventive medicine easy to dismantle and hard to defend.(没有人能说出疫苗拯救了哪些人，因为被预防的伤害从定义上讲是看不见的，而这种看不见正是预防医学容易被拆解、难以捍卫的原因。)
在重症监护领域工作四十年，让我明白一种感受一旦成为国家政策会付出怎样的代价。本不需要住院的儿童将会住院，其中一些将会死亡。没有人能说出疫苗拯救了哪些人，因为被预防的伤害从定义上讲是看不见的，而这种看不见正是预防医学容易被拆解、难以捍卫的原因。
The order rests on(基于，依赖于) a single complaint, stated in the White House’s own fact sheet(情况说明书): American children are recommended more vaccine doses(剂量) than children anywhere in the developed world, 84 doses across 57 injections(注射，针剂) by 2024 against 23 doses in seven injections in 1980. Section 2 of Monday’s executive order directs that the MMR be given as three single-disease shots, and that “to the maximum extent feasible(在最大可行范围内), all childhood immunizations should be administered at separate medical visits”. Not only the MMR: every childhood immunization.
该行政令基于一个单一的抱怨，白宫自己的情况说明书中如此陈述：美国儿童被推荐的疫苗剂量比发达国家任何地方的儿童都多，到2024年，共84剂、57次注射，而1980年是23剂、7次注射。周一行政令的第2节指示，麻腮风疫苗应作为三种单病种疫苗分别接种，并且“在最大可行范围内，所有儿童免疫接种应在不同的医疗就诊中进行”。不仅仅是麻腮风疫苗：所有儿童免疫接种都是如此。
