Malaria Vaccine Shows Promise

NEW YORK (AP) - Researchers are reporting promising results for
what may become the world's first malaria vaccine.
In early tests, the experimental vaccine was more than 50
percent effective in preventing the deadly disease in infants and
young children in Africa. A larger and longer test is set to begin
early next year.
It is the first malaria vaccine to make it this far in
development. Findings from two studies of the vaccine were released
Monday at a tropical medicine meeting in New Orleans.
Malaria kills an estimated 1 million people each year, mostly
young children in sub-Saharan Africa. It is caused by a parasite
and is spread through a bite from an infected mosquito.
