Ebola Patient Making Progress

The Nebraska doctors treating the Worcester man who became infected with Ebola while working in Liberia say he is making progress, but it's not yet clear if he will recover.

Dr. Rick Sacra arrived at the Nebraska Medical Center on Friday for treatment in the hospital's specialized 10-bed isolation unit. Two of the doctors treating him gave an update on his condition Sunday.

Dr. Phil Smith says Sacra remains very tired, but his progress has been encouraging.

Sacra has been helping with his own treatment by providing information about Ebola to the doctors because he saw it in Africa.

Smith says Sacra has even made a few jokes with the doctors treating him.

The 51-year-old Sacra is the third American aid worker to be sickened with the Ebola virus.

Meanwhile, a vaccine may have been developed for the deadly Ebola virus.

Monkeys infected with Ebola five weeks after they were given an experimental vaccine by global healthcare company GlaxoSmithKline survived without developing any symptoms of the virus. All of the monkeys injected with the vaccine survived Ebola while those going unprotected died within six days.
