CNN — U.S. researchers say they've successfully tested a vaccine for malaria on a small group of volunteers and hope to conduct large-scale tests soon.
The vaccine involves multiple, intravenous injections of a weakened form of the disease, scientists from the National Institutes of Health, the Navy, Army and other organizations reported Thursday. Though the results were promising, more extensive field testing will be required, the researchers wrote.
The mosquito-borne tropical disease kills about 1 million people a year and sickens more than 200 million. There is no current vaccine.
