Ebola vaccine seems safe in first-stage testing
By By [sic] LAURAN NEERGAARD, AP Medical Writer
WASHINGTON — An experimental Ebola vaccine appears safe and triggered signs of immune protection in the first 20 volunteers to test it, U.S. researchers reported Wednesday. The vaccine is designed to spur the immune system's production of anti-Ebola antibodies, and people developed them within four weeks of getting the shots at the National Institutes of Health. Half of the test group received a higher-dose shot, and those people produced more antibodies, said the study published in the New England Journal of Medicine. Some people also developed a different set of virus-fighting immune cells, named T cells, the study found. That may be important in fending off Ebola, as prior research found that monkeys protected by the vaccine also had that combination response.
