(CNN) – The Spanish nurse’s aide who contracted Ebola after treating virus-stricken patients in Madrid is now free of the virus, her doctors announced Tuesday after another test on her.
Teresa Romero Ramos is clear of Ebola, physicians at Carlos III hospital said.
She received an initial test, which turned up no virus in her blood, doctors said Sunday. More tests were administered to be sure she was virus-free.
While Spain welcomes the good news about Ebola, testing on one vaccine has begun at the National Institutes of Health in Maryland, and a trial for a second vaccine, initially developed in Canada, has started at the Walter Reed Army Institute of Research in Silver Spring, the World Health Organization said Tuesday.
