Read the conclusion below.
Scientists can use existing vaccines to develop vaccines for new viruses.
Which detail from the article provides the BEST support to the statement above?
(A) Inovio became one of the first companies to develop a vaccine against MERS. (That vaccine is still experimental.)
(B) Early in the latest outbreak, Chinese researchers posted details of the genetic makeup of the virus that was making so many people sick.
(C) "We'd all hoped that there would be enough overlap that our previously developed MERS vaccine would be helpful in this case," she recalls.
(D) Vaccines usually are made from weakened or killed forms of viruses or parts of viruses.

C) "We'd all hoped that there would be enough overlap that our previously developed MERS vaccine would be helpful in this case"

Explanation:

This is the conclusion from the article "Search speeds up for vaccine against the new

coronavirus" which deals with existing efforts and problems in making an efficient vaccine against the new coronavirus.

Looking at the conclusion and the given answers we can see that C. is the best fitting answer because it suggests the scientist's hope that an already existing vaccine could be helpful with the new disease.

That basically means that vaccines we currently have on our disposal, can be used as a basis for developing a new vaccine, if the antigens (genetic makeup) of the causing agents overlap sufficiently.

a, b, and c are all correct.
