Until now, only injectable vaccines against influenza have been available. Parents are reluctant to subject children to the pain of injections, but adults, who are at risk of serious complications from influenza, are commonly vaccinated. A new influenza vaccine, administered painlessly in a nasal spray, is effective for children. However, since children seldom develop serious complications from influenza, no significant public health benefit would result from widespread vaccination of children using the nasal spray.
Which of the following is an assumption on which the argument depends?

Which of the following is an assumption on which the argument depends?
A. Any person who has received the injectable vaccine can safely receive the nasal-spray vaccine as well.
B. The new vaccine uses the same mechanism to ward off influenza as injectable vaccines do.
C. The injectable vaccine is affordable for all adults.
D. Adults do not contract influenza primarily from children who have influenza.
E. The nasal spray vaccine is not effective when administered to adults.
D. Adults do not contract influenza primarily from children who have influenza. 这个论题建立的基础就是小孩不接种也没有关系(大人不会被小孩传染),如果大人主要都被小孩传染,那小孩必须要接种了。。。那普及小孩接种就有社会意义了。所以D对。
E. The nasal spray vaccine is not effective when administered to adults. 但对成人来说,无痛接种是有社会意义的,所以,E错。

大人能接受注射型也能接受鼻喷型疫苗。与应用鼻喷的好处无关,杀。
B The new vaccine uses the same mechanism to ward off influenza as injectable vaccines do.
无关信息,杀
C The injectable vaccine is affordable for all adults.
无关
D Adults do not contract influenza primarily from children who have influenza.
小孩不传染给大人流感。小孩子自己打不打无所谓,因为他们都不会有流感反应。如果他们不给大人传染病,小孩子就更没有理由打鼻喷式疫苗了,对。
E The nasal spray vaccine is most effective when administered to adults.
莫名奇妙的比较。杀。文中问的是小孩子打疫苗的必要性。
目的:解释不广泛应用鼻喷在小孩子身上的合理性。
逻辑:背景/小孩子怕疼,小孩子没有严重的流感症状,大人有流感症状,大人都接受注射型疫苗。
现在有一个不疼的鼻喷疫苗,可以给小孩子有效的保护。但是事实是小孩子没有严重的流感症状,打不打对小孩子都一样。然而对大人,如果小孩子对大人有传播流感的能力,小孩子就必须打疫苗。如果小孩子不传播给大人流感,那小孩子打不打疫苗都行。D选项否定了小孩子必须打疫苗的唯一必要,所以这种鼻喷型疫苗,小孩无需打。
没有public benefit.
