trials. in fact wolf, you may remember some time ago we did a phase one trial right here in bethesda of that same vaccine, by phase one we mean to determine whether it s safe and what the right dose is. so this is a safe vaccine tested here and tested in europe tested in africa on much much larger number of people than were actually in the vaccine trial in guinea. so we feel comfortable about the safety of the vaccine. and what about side effects? again side effects, you see that with any vaccine. it s a having seen that s made of a live virus which has nothing to do with ebola. and what you do is you take one of the genes of ebola and stick it into that vie vous that you can make ebola protein. you get side effects, sometimes fever, sometimes pain in the arm but there haven t been any prohibitive side effects that
reporter: at the institute for protein design, biochemistry students are teaming up with gamers who play fold it. an interactive, online game developed by the university. that lets players tackle puzzles for science. if all the players are very, very ingenious and intelligent. and they, they have developed algorithms that parallel our algorithms. reporter: the ebola challenge is to fold a protein in the best position to stick to the ebola protein. this is a good starting place for drug design. reporter: 500 gamers from around the world took on the last ebola challenge. several came up with top scoring solutions for jamming the virus s ability to infect people. proteins can have many many, many different types of structures, and the computer cannot survey all possible structures. so gamers are coming up with new types of structure that is have
