Breakthrough in malaria vaccine

This is fantastic news if the results hold (CNN via Instapundit):

More than three dozen volunteers received multiple, intravenous doses of a vaccine produced with 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. Nevertheless, the it marks the first time any vaccine trial has shown 100% success in protecting subjects from the mosquito-borne tropical disease, which sickens more than 200 million a year and killed about 660,000 in 2010.
