WHO: Ebola Vaccine Could Be in Use by January by VOA News The [1]World Health Organization says an experimental Ebola vaccine could be in use by January. WHO assistant director Dr. Marie Paule Kieny said Tuesday that clinical trials of Ebola vaccines were underway or planned in Europe, the United States, and Africa. She said if the vaccines were deemed safe, there could be a West African trial in January, using tens of thousands of doses. Kieny, speaking to reporters in Geneva, did not say when an Ebola vaccine might be widely available. There is no cure or vaccine for the disease, which has killed more than 4,500 people in West Africa this year. On Monday, the WHO declared the nation of Nigeria free from Ebola after 42 days passed with no new reported cases. But Nigerian President Goodluck Jonathan has directed all anti-Ebola measures in Nigeria to remain in effect, including health screenings for people entering the country. Nigeria had 20 cases of Ebola and eight deaths as part of the worst-ever outbreak of Ebola. In the United States, the [2]Centers for Disease Control and Prevention (CDC) announced tighter guidelines for healthcare workers taking care of Ebola patients. CDC officials issued the new procedures late Monday, saying that a health workers' protective clothes must leave no part of the body exposed and that a trained monitor must supervise workers as they put on and take off the clothing. In the southwestern U.S. city of Dallas, officials announced Monday that the 21-day quarantine has been lifted on 43 people who had contact with the state's first Ebola patient. But Dallas Mayor Mike Rawlings said 120 others who had contact with one of the other Ebola patients were still being watched for signs of the virus. Also in the United States, health workers at a special Ebola treatment unit said another patient has recovered from the virus. The man, who was not identified, was infected with Ebola while in Sierra Leone and was airlifted to the eastern U.S. city of Atlanta. Separately, a United Nations spokesman said a staff member from U.N. Women in Sierra Leone died of Ebola in recent days, the third reported death of a U.N. worker from Ebola. Liberia, Guinea, and Sierra Leone have been the hardest hit by the Ebola outbreak, with more than 9,100 cases.
