a: vaccine ~
b: the scrap of clothing
What:
"Most vaccines against viruses work by prompting our bodies to produce antibodies that latch on to and neutralize the virus. Figuring out where on the virus to target antibodies is a critical issue in the development of a vaccine. A vaccine is like the scrap of clothing investigators use to put a bloodhound on to a fugitive's scent; by presenting specific viral fragments, a vaccine trains your body's immune system to recognize the virus "
