(CNN) - The "extraordinary" rush to develop an Ebola vaccine is moving forward apace, the lead researcher told CNN's Christiane Amanpour on Tuesday, adding that the fast pace may engender ethical concerns about how it the vaccine is eventually implemented.
"This is, frankly, extraordinary," Adrian Hill of the Jenner Institute at Oxford University said. "We are trying to do in a few months something that might typically take 10 years. We've had accelerated reviews of all our applications, regulatory and ethical approvals, and so on."
"And we're now trying to proceed so quickly that if things go well, by the end of the year, this vaccine might actually be being used in the three affected countries in West Africa."
