FOXNews.com - Experimental Ebola Vaccine Used on Human - Infectious Diseaseより、
A scientist accidentally pricks her finger with a needle used to inject the deadly Ebola virus into lab mice.
（略）
Within 24 hours, an experimental vaccine ― never before tried on humans ― was on its way to Germany from a lab in Canada.
Within 40 hours, the at-risk scientist was injected with the vaccine.
So far, so good. If the woman is still healthy on April 2, she can consider herself safe.

But was it because the vaccine worked, or because she didn't receive enough virus to cause an infection? It should be possible to tell. A vaccine would only prompt the production of antibodies to the one Ebola protein it carries. Infection would produce antibodies to many different Ebola proteins.
Stephan Günther, head of virology at the BNI, says the woman has very low levels of antibodies. These might be caused by the vaccine: when it was tested on monkeys it elicited only low levels of antibodies, but they were enough to protect the animals from Ebola. "We don't know if this might also result from a mild infection," Günther says.
