Final trials show Ebola vaccine offers 100 percent protection

A new Ebola vaccine is safe to use and highly effective against the deadly virus, scientists say, following successful trials in Guinea and Sierra Leone. The scientists’ study, published in the Lancet, notes that zero cases of Ebola were reported in Guinean subjects vaccinated with rVSV-ZEBOV immediately after contact with another Ebola patient, suggesting a 100 percent success rate against the disease. The vaccine was hurried into development after last year’s outbreak of the disease in west Africa in which more than 10,000 people are believed to have died. Scientists had previously struggled to combat the Ebola virus, but the new vaccine was found to be so effective that control group tests were halted early in Guinea, allowing everyone exposed to the disease to be immunized. Scientists had previously split the test subjects up, giving some the vaccination immediately after Ebola contact, and waiting three weeks before providing it for others. 5,837 people...
