Jamboree Question of the Day - Day 74, Jan 24th 2011

Even today, a century after Pasteur developed the first vaccine, rabies almost always kills its victims unless inoculated in the earliest stages of the disease.

(A) its victims unless inoculated

(B) its victims unless they are inoculated

(C) its victims unless inoculation is done

(D) the victims unless there is an inoculation

(E) the victims unless inoculated

Solution (Posted on 25th):
Choice A comes as though rabies is inoculated. C is also unclear. D has 'there' - ambiguous pronoun, E has the same problem as A. Thus, B remains.
