Infection of Aedes albopictus and Aedes aegypti mosquitoes with dengue parent and progeny candidate vaccine viruses: a possible marker of human attenuation.

Abstract excerpt

Dengue (DEN-1) and DEN-4 parent (P) and progeny candidate vaccine (CV) viruses were compared in their abilities to infect and to replicate in Aedes aegypti and Aedes albopictus mosquitoes. The DEN CV clones were temperature sensitive (ts) and had small plaque morphology. The DEN-1 and DEN-4 CV viruses differed in their ability to infect, to replicate in, and to be transmitted by mosquitoes. The DEN-1 CV virus was...
