Several inexpensive new vaccines have recently been developed that may help eliminate malaria, a disease that is believed to kill more than 2 million people worldwide each year. All of these vaccines, however, can sometimes produce acute, albeit short-lived and rarely fatal, side effects, the most unpleasant of which are intense diarrhea and severe skin reactions. Countries with the highest incidence of malaria should begin implementing as soon as possible a vaccination program using the vaccine that has shown the lowest incidence of severe skin reactions as a side effect.
Each of the following, if true, gives support to the recommendation above, EXCEPT:
A. The severe skin reactions caused by the new vaccines are rated as slightly more unpleasant by those who have experienced them as compared to the intense diarrhea.
B. The new vaccine that has shown the lowest incidence of severe skin reactions as a side effect costs approximately the same per dose as the other new vaccines.
C. The diarrhea that is a side effect of these vaccines is no more life threatening than the skin reactions that are a side effect of these vaccines.
D. In treating patients with intense diarrhea as a side effect of one of these vaccines, it is sometimes necessary to resort to I.V. hydration.
E. All of the recently developed new vaccines have shown the same incidence of intense diarrhea as a side effect.
Conclusion: Countries should use a vaccination program that has shown the lowest incidence of severe skin reactions as a side effect.
Answer: To pick a choice which DOES NOT explain (directly or indirectly) why Countries should use a vaccination program that has shown the lowest incidence of severe skin reactions as a side effect. In other words, a choice which can actually pin point either
(1) side effects of skin reactions are worse than diarrhea, or
(2) there are varied incidences (not same no. of incidences) of skin reaction as a side effect in different vaccines.
A. The severe skin reactions caused by the new vaccines are rated as slightly more unpleasant by those who have experienced them as compared to the intense diarrhea.
Explains point (1)B. The new vaccine
that has shown the lowest incidence of severe skin reactions as a side effect costs approximately the same per dose as the other new vaccines.
Explains point (2) - It says
the vaccine that has the lowest incidence: suggests that there are vaccines with more incidences.
C. The diarrhea that is a side effect of these vaccines is no more life threatening than the skin reactions that are a side effect of these vaccines.
Explains point (1)D. In treating patients with intense diarrhea as a side effect of one of these vaccines, it is sometimes necessary to resort to I.V. hydration.
Explains neither (1) nor (2), hence the AnswerE. All of the recently developed new vaccines have shown the same incidence of intense diarrhea as a side effect.[/quote]
Explains point (2) - It says that incidence of intense diarrhea is same in all vaccines, leaving a choice for us to assume that there are varied incidences of skin reaction.
