Scientists in Cuba say they have made significant progress towards developing a vaccine to fight the mosquito borne virus that causes dengue fever.
In making the announcement, the president of the BioCubaFarma Biotech Conglomerate Eduardo Martinez said a diagnostic system is also being developed to detect the disease as the first symptoms appear.
Cuban scientists have worked over the last 10 years to find a vaccine against dengue.
Dengue fever is a mosquito-borne illness that occurs in tropical and subtropical areas of the world.
