Provita Pharmaceutical is working on a project (with funding from the Gates Foundation) to use mosquitoes to help carry vaccines against the West Nile Virus.
The first goal: to genetically engineer mosquitoes so that they can produce and deliver a vaccine via their saliva. It’s a new twist on research being done elsewhere to breed sterile mosquitoes in malaria-infested areas.
And, everyone on the 15-plus person Provita team, from research and development workers to finance officers, is under the age of 18 and still in high school.

















At the Vanderbilt Children’s Hospital in Nashville, Tenn., it is not uncommon for the crisp, clean, soothing sound of an acoustic guitar to echo down the hallway.
