ScienceDaily (June 11, 2010) — There is no vaccine for malaria, which sickens almost a quarter of a billion people each year and kills a child every 30 seconds. That could be changing: researchers at The Rockefeller University have genetically transformed the yellow fever vaccine to prime the immune system to fend off the mosquito borne parasites that cause the disease. The researchers found that the modified vaccine, along with a booster, provided mice with immunity to the deadly disease.
