Ebola vaccines are so effective in monkeys that macaques can be protected or rescued even if they're injected with a hundred times the lethal dose of the Ebola virus after vaccination. But no one knows for certain whether the vaccines will work in humans; the vaccines haven't yet been rigorously tested in people.

Just developing the vaccines to test in monkeys was a grueling, decades-long process that has killed scores of macaques since the 1990s.

WASHINGTON- President Barack Obama on Saturday urged Americans not to succumb to hysteria about Ebola, even as he warned that addressing the deadly virus would require citizens, government leaders and the media to all pitch in.

in his weekly address, Obama also pushed back against calls for the US to institute a travel ban. Lawmakers have called it a commonsense step to prevent more people with Ebola from entering the US, but Obama said such a ban would only hamper aid efforts and screening measures.

“Trying to seal off an entire region of the world – if that were even possible – could actually make the situation worse,” the president said.

Growing US concern about Ebola and the three cases diagnosed so far in Dallas prompted Obama on Friday to tap a former top White House adviser to be his point person on Ebola. Striking a careful balance, Obama said there was no “outbreak” or “epidemic” of Ebola in the US, but said even one case was too many.

“This is a serious disease, but we can’t give in to hysteria or fear – because that only makes it harder to get people the accurate information they need,” Obama said. “We have to be guided by the science.”

Senegal's first and only confirmed Ebola patient traveled to the country by road from Guinea in August, bringing the virus with him. Officials confirmed his Ebola diagnosis on Aug. 29. But samples from this index patient tested negative for Ebola on Sept. 5, "indicating that he had recovered from Ebola virus disease," the WHO said in a news release.

By Sept. 18, the patient was fully recovered and returned to Guinea.

According to the WHO, Senegal officials kept track of 74 close contacts of the patient -- people who were at risk of contracting Ebola themselves. None of those contacts showed symptoms or tested positive for the disease.
