WHO regional director for Africa Dr. Matshidiso Moeti said Thursday that 11,000 Ebola vaccines are being prepared in Geneva and are expected to arrive in Guinea over the weekend.
The WHO has called on six African countries to be on high alert for Ebola infections after both Guinea and Congo recorded cases in recent weeks.
As of Thursday, Guinea has recorded three confirmed Ebola cases, including one death, according to WHO.
Health officials hope to stem the spread of Ebola in West Africa, which experienced the deadliest Ebola outbreak in history from 2014 to 2016 that killed more than 11,300 people, mostly in Guinea, Liberia and Sierra Leone.
Tests have since shown he was negative for Ebola, according to Ministry of Health and Sanitation spokesman Harold Thomas.
